2: Timeline of Naruto Universe
and him is 5 years, but as Sasuke acknowledges that his brother defected at 13, this statement can be ignored. Itachi Shinden also states that Itachi and Izumi are the same age, and establishes a 25 year age gap between Izumi and her mother. Tsume is roughly 18 years older than her daughter. Notably, this would bring her below the age of majority at the time of her eldest child's birth.
• Year 60: Ayame is born
• Characters: Teuchi age 25
• Notes: Ayame is approximately 1 year younger than Itachi. While Teuchi might have been older than 25 given the age gap discrepancies from the data books, for the sake of consistency, his age is assumed as the above.
• Year 60: Momochi Zabuza graduates from Kiri's Ninja Academy; at some point prior to this, Zabuza massacres over one hundred Kiri students and Kiri is forced to change its graduation ceremony
• Characters: Zabuza age 9
• Notes: According to the data books, Zabuza graduated at the age of 9. However, his massacre of over one hundred Academy students is said to have occurred when he was not yet a student in Chapter 14, so it must predate this time.
• Year 60: Uchiha Obito and Nohara Rin become Chunin
• Characters: Obito and Rin age 11; Kakashi age 9
• Notes: Obito and Rin both were promoted to Chunin at the age of 11 according to data book entries.
• Year 61: Shiranui Genma and Maito Gai become Chunin
• Characters: Gai age 11; Genma age 13
• Notes: Gai and Genma become Chunin at the age of 11 and 13 respectively according to the data books.
• Year 62: Sasori kills the Third Kazekage and turns him into a human puppet; Rasa becomes Fourth Kazekage
• Characters: Sasori age 16; Rasa age 24
• Notes: Chiyo describes the disappearance of the Third Kazekage as having taken place over ten years prior to the events of Part II (Chapter 267). However, as in Chapter 547, Chiyo implies that Rasa was in charge of the fate of Shukaku for all three of his children's births ("This is our third child. So far he's the only one that's compatible") it suggests that Rasa became Kazekage before Temari was born, thus dating this event. As all Kazekages until Gaara died by assassination, it is highly unlikely that Rasa was named successor while the Third Kazekage was still alive. Interestingly, it also means that Sasori would have weakened his own village in and around the Third Shinobi War, despite fighting in it himself to gain the moniker Akasuna no Sasori.
• Year 62: Temari and Deidara are born
• Characters: Rasa age 24
• Notes: According to the data books, Deidara is age 19 at the time of his death in Part II. Temari is 3-4 years older than Gaara and so was born this same year.
• Year 62: Shizune, Kurenai and Asuma become Chunin; Tsunade and Shizune leave the village
• Characters: Tsunade age 36; Shizune, Kurenai and Asuma age 12-13
• Notes: Asuma and Kurenai were promoted to Chunin at the ages of 12 and 13 respectively. Although the anime places Raido on this team also, it is debatable whether or not that's relevant, especially since Raido is approximately 4 years older and has no stated graduation age. Since Konoha's Chunin exams are done in teams, it's presumed that Shizune stayed in Konoha until she became a Chunin. Since Tsunade leaves the village with Shizune in tow, it seems as though she would've been living in Konoha semi-retired for 9 years. This also places their departure right around the beginning of the war, which makes a lot of sense if Tsunade did not want to get pulled into combat/medicine.
• Year 62: Third Shinobi War (Battle of Kannabi Bridge); Hatake Kakashi becomes a Jonin; Uchiha Obito is presumed dead
• Characters: Obito and Rin age 13; Kakashi age 11
• Notes: Obito is aged 13 at the time of his presumed death. Although Kakashi's promotion age to Jonin is stated to be 9 in the data books, this would make him 9 at the time of Kannabi Bridge, and that much of an age difference doesn't seem feasible based on the sizes + relationships between Team Minato. A two-year gap accounts for Kakashi's early promotions without affecting the other elements of the team. Thus, in this timeline, Kakashi's ages of promotion are: Genin ~5; Chunin ~6/7; Jonin ~11
• Known conflicts: Konoha v. Iwa (Third Tsuchikage's reign)
• Year 62: Third Shinobi War continues; Maito Dai dies in battle against the Swordsman of the Mist
• Characters: Gai age 12; Ebisu age 14; Genma age 14-15; Dai age 35
• Notes: During Chapter 668, Gai notes that his father is a genin and shouldn't be on the battlefield, suggesting that at this time Gai is already a Chunin. As Gai became a Chunin at age 11, he must be at least 11, but more than likely a little older because of the timeline of the war. Based on his appearance, Gai is likely around 12, marking the ages of his teammates. According to the data books, Dai is 35 when he dies.
• Known conflicts: Konoha vs. Kiri (Fourth Mizukage's reign OR Madara's shadow reign)
• Year 62: Yuki Haku, Kaguya Kimimaro and Jugo are born
• Characters: Zabuza age 11
• Notes: Haku is 3 years older than Naruto during the events of Part I, thus he is born 3 years before him in the Year 62. Kimimaro and Jugo are both the same age as Haku.
• Year 63: Kurotsuchi is born
• Characters: Kitsuchi age 26
• Kurostuchi is 18 at the time of her appearance in Part II according to the data books, suggesting she is born sometime between the Year 62-63. Kitsuchi is older than his daughter.
• Year 63: Mitarashi Anko graduates from the Academy; Team Orochimaru is formed
• Characters: Anko age 10; Orochimaru age 36
• Notes: According to the data books, Anko graduates from the academy at the age of 10. Orochimaru is approximately 26 years older than Anko.
• Year 63: Nohara Rin dies by Hatake Kakashi's hand; Uchiha Obito and Hatake Kakashi awaken the Mangekyo Sharingan
• Characters: Kakashi age 12-13; Rin and Obito age 14
• Notes: Rin dies while Konoha is still at war, so this year is most likely since the following year would be the end of the war. Obito is in rehabilitation long enough to grow out his hair past his shoulders and relearn to walk, so it's likely to have taken place approximately one year after Kannabi Bridge.
• Known conflicts: Konoha v. Kiri (Madara's shadow reign of Fourth Mizukage)
• Year 63: Namikaze Minato faces A (Fourth Raikage) and Killer Bee on the battlefield during the Third Shinobi War
• Characters: Minato age 22; Killer Bee age 19; A (Fourth Raikage) age 30
• Notes: In Chapter 542, Minato faces the A-B combo in a mission during the war, before either of them has taken on the title of Kage. Since A's father dies at the end of the war, this event must occur sometime previous to the war end. I posit that the "other mission" Minato had at the time of Rin's death was facing these ninja.
• Known conflicts: Konoha v. Kumo (Third Raikage's reign)
• Year 63: Hanzo confronts the first iteration of Akatsuki; Yahiko dies
• Characters: Yahiko and Nagato age 18
• Notes: Hanzo's confrontation took place during the Third Shinobi War, so it must take place at some point prior to the war's end in Year 64. Notably, this age is contradictory to sources that suggest Yahiko died at 15, but the increase in age does bring him closer to the 25-30 range that Deva Pain is estimated to be during Battlefield Konoha, as he'd likely be fully grown by age 18. Nagato's influence over the body may bridge the age gaps.
• Year 63: Uchiha Madara dies; Obito begins to control Akatsuki from the shadows
• Characters: Madara age 88; Obito age 14
• Notes: Madara dies after Rin is killed, as he is the one who orchestrates her death, but before Minato dies, because Obito acts independently to attack Konoha. This dates Madara's death to the Year 63.
• Year 63: Kankuro is born
• Characters: Rasa age 25; Temari age 1
• Notes: Kankuro is 2-3 years older than Gaara and approximately 1 year younger than Temari and so was born Year 63, roughly between their birth dates. It should be noted that this is more in alignment with his given age in the Third Data book, which puts him at 18 in Part II, rather than the First, which suggests that he is 14 in his first appearance.
• Year 63-64: A (Third Raikage) dies after battling ten thousand shinobi for three nights; A (Fourth Raikage) assumes his title and restricts Killer Bee to the village
• Characters: A (Fourth Raikage) age 30-31; Killer Bee age 19-20
• Notes: According to Chapter 543, at some point before the end of the war, The Third Raikage dies and the Fourth Raikage is named, with A shortly after deciding to limit Bee's movements outside the village.
• Year 64: Yakushi Kabuto is found by Yakushi Nono and taken into a Konoha orphanage
• Characters: Kabuto age 7; Urushi age 8; Nono age 24
• Notes: Kabuto's age is conjectural based on his appearance in Chapter 582, but it fits within the constructed timeline of his having spent three years at the orphanage (Chapter 583) and four years in Root. Nono's age is inferred on the same premise. Urushi, Kabuto's adopted brother, is one year older than him according to the data books.
• Year 64: Third Shinobi War ends; Hyuga Neji, Rock Lee, Tenten, Sai, Karui, Tsuchi Kin, Abumi Zaku, and Kinuta Dosa are born
• Characters: Hizashi age 27
• Notes: Itachi is approximately 5 years old at the end of the Third War (Itachi Shinden), thus dating the war's end. Team Gai is one year older than the Rookie 9. Sai and Karui are both the same age as Team Gai in Part II (approximately 17) so they are born this same year. Kin, Zaku, and Dosu who takes the Chunin exams as Otogakure Genin in Part I, are 14 at the time of their appearance according to the first data book, thus being the same age as Team Gai.
• Year 64: Namikaze Minato is named Hokage; Kakashi joins ANBU
• Characters: Minato and Kushina age 23; Kakashi age 13
• Notes: Hiruzen steps down as a result of the the Third Shinobi War, dating Minato's promotion to after the war. Kakashi becomes a member of ANBU under Minato's leadership.
• Year 64-65: Konoha's Rookie 9 are born (Uchiha Sasuke, Haruno Sakura, Hyuga Hinata, Inuzuka Kiba, Aburame Shino, Yamanaka Ino, Nara Shikamaru, Akimichi Choji); Uzumaki Karin and Hozuki Suigetsu are born (at some point prior to this but not before Year 51, Hozuki Mangetsu is born); Omoi is born
• Characters: Yoshino and Tsume age 23-23; Shikaku, Inoichi and Choza age 24-25; Shibi age 26; Mikoto and Hiashi age 28; Fugaku age 33
• Notes: Sasuke is born in the Year 65 because he is only a few months old at the time of the Kyubi attack. Hiashi is 3 years older than Ino-Shika-Cho according to the data books, while Tsume is 1-2 years younger. Shibi is older than Ina-Shika-Cho but younger than Mikoto. Mikoto and Fugaku's ages are derived from the knowledge that they die at 35 and 40 respectively, when Sasuke is 7. These ages are largely approximates as they are not incorporating actual day-month birth dates of adults or children. According to the data books, Karin and Suigetsu are both approximately the same age as Sasuke in Part II. Mangetsu was born after Zabuza according to Chapter 523, since it was because of him he got his nickname. According to the data books, Omoi is 1 year younger than Karui.
• Year 64-65: Team Orochimaru takes the Chunin Exams; Mitarashi Anko becomes a Chunin
• Characters: Anko age 12
• Notes: According to the data books, Anko is promoted to Chunin at the age of 12. There is a slight contradiction in terms of team ages and promotions, as Anko is seen taking the Chunin exam together during the same exam as Team Minato and Team Choza in Chapter 599, in spite of the fact their age difference would her place as age 4-5, too young to have graduated. Here, I choose to value team composition and promotion ages over manga imagery.
• Year 65 (October 10): Uchiha Obito unleashes Kyubi on Konoha; Sarutobi Biwako is killed by Uchiha Obito; Umino Ikkaku, Umino Kohari, Namikaze Minato and Uzumaki Kushina die fighting against the Kyubi; Uzumaki Naruto is born; Sarutobi Hiruzen reassumes role of Hokage
• Characters: Iruka age 11; Kakashi age 14; Obito age 16; Minato and Kushina age 24; Ikkaku and Kohari age 45; Biwako age 55; Hiruzen age 57
• Notes: Biwako, Ikkaku and Kohari's ages at the time of their appearances are derived from the data books.
• Year 65: Umino Iruka graduates from the Academy; Ebisu becomes a Chunin
• Characters: Iruka age 11; Ebisu age 17
• Notes: Iruka graduates from the academy at the age of 11, but notably after the Kyubi attack as the loss of his parents drives him to become a class clown (Chapter 1). Ebisu becomes a Chunin at the age of 17 according to the data book. Provided that he was Gai and Genma's third partner in their second Chunin exam, this implies that it took Ebisu three tries to pass.
• Year 66: Orochimaru becomes a missing nin
• Characters: Orochimaru age 40; Hiruzen age 58
• Notes: As Orochimaru defecting comes partly as a result of Minato being named Hokage, it must occur after. The manga and anime imply that the defection takes place shortly after Hiruzen reassumes the role Hokage. Itachi Shinden states that Orochimaru leaves the village 6 years prior to the massacre, which dates it no later than the year 66.
• Year 66: Uchiha Itachi graduates from the Academy
• Characters: Itachi age 7
• Notes: When Sasuke begins the academy at the age of 7, we are told that Itachi graduated by that age, thus dating this event.
• Year 66: Gaara is born and becomes Suna's jinchuriki
• Characters: Rasa age 28; Chiyo age 58
• Gaara is 1 year younger than Naruto, so was born the year after him in Year 66. According to Gaara's statement in Chapter 97, the Ichibi, Shukaku, was sealed into him at birth.
• Year 66: Gekko Hayate graduates from the Academy; a team composed of Gekko Hayate, Morino Ibiki and Tokara takes the Chunin exams
• Characters: Hayate age 11-12; Ibiki age 15
• Notes: Hayate graduates from the academy at the age of 12. There is a slight contradiction in terms of team ages and promotions, as Hayate and Ibiki are seen taking the Chunin exam together during the same exam as Team Minato and Team Choza in Chapter 599, in spite of not all members of that team having graduated, according to the data books (additionally, this would place Hayate at around 3-4 at the time of the first exam). Here, I choose to value team composition and promotion ages over manga imagery.
• Year 67: Izumo Tenma dies by Uchiha Obito's hand; Uchiha Itachi awakes the Sharingan
• Characters: Itachi age 8; Tenma age 12; Obito age 18
• Notes: According to Chapter 142, Itachi is able to use the sharingan by the age of 8. Itachi Shinden reiterates this point and further adds the detail that Itachi awakens his sharingan as a result of the death of his teammate by Obito's hand.
• Year 67: Yakushi Nono and Yakushi Kabuto are recruited into Root
• Characters: Kabuto age 10; Nono age 27
• Notes: In Chapter 583, Kabuto infiltrates four different villages, aging in each panel, suggesting the passing of years. In keeping with Nono's known age at death and the changes in Kabuto's appearance, they would be four years younger at the time of their recruitment. This is also supported by Kabuto's Academy graduation age in the Third Data Book, which is 10 years old.
• Year 68-69: Kumo ninja try and fail to kidnap Hyuga Hinata; Hizashi Hyuga is killed in his brother's place as a result of the incident
• Characters: Hinata age 3; Neji age 4; Hizashi and Hizashi age ~31-32
• Notes: The Hyuga incident takes place ten years prior to the events of Part II and the data books state that Hizashi was approximately 32 when he died. In order to maintain the correct age difference between the elder Hyuga and their children, 31 seems a better estimate. This also complies with the constructed timeline for Hiashi's birth year.
• Year 69: Team Ebisu is born (Sarutobi Konohamaru, Kazamatsuri Moegi and Udon); Uchiha Itachi becomes a Chunin
• Characters: Itachi age 10
• Notes: Konohamaru is approximately 4 years younger than Naruto, who is born 4 years prior in the Year 65. His classmates are the same age. Itachi Shinden and the data books establish that Itachi becomes a Chunin at age 10.
• Year 70: Inari is born
• Characters: Tsunami age 21; Tazuna age 51
• Notes: According to the data books, Inari is 4-5 years younger than Naruto. He is between the ages of Konohamaru and Hanabi, and is younger than his grandfather Tazuna by 51 years, and his mother Tsunami by 21 years.
• Year 70: Umino Iruka becomes a Chunin; Hyuga Hanabi is born
• Characters: Iruka age 16; Hiashi age 33; Hinata age 5
• Notes: According to the data books, Iruka becomes a Chunin at the age of 16. According to Chapter 78. Hanabi is 5 years younger than Hinata.
• Year 70: Uchiha Itachi joins the ANBU; Uchiha Izumi graduates from the Academy; Konoha implements a minimum graduation age of 11
• Characters: Izumi and Itachi age 11; Tenzo age 16; Kakashi age 19
• Notes: According to Itachi Shinden, Itachi joins the ANBU at the age of 11, when Kakashi is approaching twenty. This would place the event at sometime before June. During the same chapter where this is noted (Chapter 4) Itachi also notes that no matter how talented Sasuke is, he cannot graduate before the age of 11. Izumi graduates sometime shortly before this policy comes into place, according to the same chapter.
• Year 70: Sarutobi Asuma becomes a Jonin instructor and forms his first Genin team; Inomatsu graduates from the Academy
• Characters: Asuma age 21; Inomatsu age 12
• Notes: Conjectural; according to the Third Data Book, Inomatsu was a genin student of Asuma prior to Team 10. His only appearance is at Asuma's funeral, at which point he is 23, denoting a nine year age difference. Inomatsu's academy graduation age is likely older than 11, as 12-13 seems a typical graduation time by Naruto's generation, and most jonin instructors appear to be in their 20s by this time.
• Year 71: Yakushi Nono dies by Yakushi Kabuto's hand; Yakushi Kabuto is recruited out of Root by Orochimaru and defects; Otogakure is founded
• Characters: Kabuto age 14; Nono age 31; Orochimaru age 45
• Notes: Based on Kabuto's appearance in Chapter 583, it seems likely that he is still a teenager when he and Orochimaru meet. It also aligns with Orochimaru describing as a child in the subsequent chapter, and the typical recruitment age for Orochimaru's subordinates. In addition, Kabuto defecting at the age of 14 would be supported by the statement that Anko makes in Chapter 66 that Kabuto, by age approximately 20-21, has failed his Chunin exams six times (likely for similar intelligence gathering purposes). In Chapter 584, Orochimaru announces his intention to create Otogakure, thus dating this event.
• Known conflicts: Konoha v. Iwa (Third Tsuchikage's reign)
• Year 71: Uchiha Shisui uses Koto'amatsukami to attempt to prevent the Uchiha Coup D'état; Shimura Danzo attacks Uchiha Shisui, obtaining his right eye; Uchiha Shisui dies by his own hand; Uchiha Itachi awakes the Mangekyo Sharingan
• Characters: Shisui age 16-17; Itachi age 12; Fugaku age 39
• Notes: According to Itachi Shinden, Shisui dies one year prior to the events of the coup. According to Chapter 590, Danzo takes Shisui's right eye to prevent him from stopping the coup d'état with koto'amatsukami, just prior to Shisui's death. Itachi awakens the sharingan as the result of Shisui's death.
• Year 71: Momochi Zabuza attempts a coup d'état on Fourth Mizukage Karatachi Yagura (controlled by Obito); Momochi Zabuza, Yuki Haku, Hoshigaki Kisame and Utakata defect from Kiri; the Kaguya clan is wiped out in their assault on Kiri
• Characters: Zabuza age 20; Haku and Kimimaro age 9; Obito age 22; Kisame age 23; Utakata age 16-17
• Notes: According to Chapter 30, shortly before Zabuza defects from Kiri, he attempts a coup d'etat. Based on Haku's appearance at the time of his defection, he is no older than ten years old, and Zabuza appears as a full grown adult. Chapter 26 and 29 suggest that Haku and Zabuza had already been companions for some time prior to their defecting. Yagura's reign of "Blood Mist Village" saw a number of defections from Kiri, including most of the ninja swordsmen and in the anime, Utakata, so it's assumed these defections happened in relatively close proximity to the kekkei genkai massacres. Notably, by this point Obito is leading Kiri, according to Chapter 507. Kisame claims in Chapter 353 of Part II that he last saw Suigetsu ten years prior, dating his defection at this time. In the anime (Episode 126) the Kaguya clan's attack on Kiri and Kimimaro's subsequent orphaning takes place at the same time as Haku's defection. Kimimaro is the same age as Haku.
• Known conflicts: Kiri internal conflict; Kiri v. Kaguya clan (Obito's shadow reign of Fourth Mizukage)
• Year 72: Yashamaru attempts to kill Gaara on Fourth Kazekage Rasa's orders before dying by his own hand
• Characters: Yashamaru age 27; Rasa age 34; Gaara age 6
• Notes: In Chapter 97, Gaara states that his father has been trying to assassinate him for 6 years, since he turned six. In Chapter 131, it is shown that the first attempt on Gaara's life is made by Yashamaru, who then takes his own life by exploding tags. The Second Data Book states that Yashamaru is 27 at the time of his death. Rasa is 28 years older than Gaara.
• Year 72: Uchiha Itachi and Uchiha Obito massacre the Uchiha clan; Uchiha Itachi joins the Akatsuki
• Characters: Itachi age 13; Obito age 23; Sasuke age 7; Mikoto age 35; Hazuki age 38; Fugaku age 40
• Notes: Itachi and Sasuke's respective ages at this time are established by both the anime and manga. Mikoto and Fugaku's ages are established by the data books. Hazuki's age and time of death are established in Itachi Shinden. Itachi Shinden implies that Itachi is one year younger than stated in other canonical sources, but since Sasuke would be aware of his brother's own age, this statement can be ignored.
• Known conflicts: Konoha internal conflict (Third Hokage's reign)
• Year 72: Orochimaru leaves the Akatsuki
• Characters: Orochimaru age 46; Itachi age 13
• Notes: Chapter 345 (as well as prior dialogue and Itachi Shinden) establishes that Itachi and Orochimaru were in the Akatsuki at the same time. Thus, Orochimaru could not have left the Akatsuki until after Itachi joined. While in Chapter 238, Sasori claims that Orochimaru left seven years prior to Part I, this statement can be ignored because that would place Itachi's age at 10-11 when Orochimaru left, and thus too young to have been in the Akatsuki. A similar statement in Chapter 353 is ignored for the same discrepancy.
• Year 74: Hatake Kakashi leaves ANBU
• Characters: Kakashi age 22-23; Yamato age 19-20
• Notes: The light novels canonize Itachi and Kakashi being in Team Ro in ANBU together, which would place his ANBU discharge at minimum age 20. It's suggested that Kakashi was still in ANBU at the time of the Uchiha massacre at age 21, an event which saw the complete decimation of the Konoha Police Force. Thus, I'm inclined to believe that no ANBU captain would've been discharged until at least a year or two after they'd lost their main internal security force. This date is supported is also supported by the anime adaptation.
• Year 74: Akamaru is born
• Characters: Kiba age 9
• Notes: Kiba is 9 years older than Akamaru according to the Third Data Book, which states that Akamaru is 7 during the events of Part II.
• Year 75: Kankuro graduates from Suna's Ninja Academy
• Characters: Kankuro age 12
• Notes: According to the Third Data Book, Kankuro graduates from the Academy at the age of 12.
• Year 77: Hyuga Neji, Rock Lee and Tenten graduate from the Academy; Team Gai is formed
• Characters: Lee, Tenten and Neji age 12-13
• Notes: Team Gai is one year older than Team 7, both in age and in experience.
• Year 78: Events of Part I inc. Rookie 9 graduate; Momochi Zabuza and Yuki Haku die; Kazekage Rasa is assassinated by Orochimaru; Konoha 11 take Chunin exams (Konoha Crush); Gekko Hayate and Sarutobi Hiruzen die; Tsunade becomes Fifth Hokage; Sasuke becomes a missing nin
• Characters: Gaara age 12; Rookie 9 age 12-13; Team Gai age 13-14; Haku and age 15; Temari age 16; Itachi age 18-19; Hayate age 23; Iruka age 23; Zabuza and Kakashi age 26; Gai age 27; Asuma and Kurenai age 28; Kisame age 29; Rasa age 40; Orochimaru, Jiraiya and Tsunade age 51-52, Hiruzen age ~69
• Notes: If going on an average Japanese school year, academy graduation likely takes place in late March or early April. In Chapter 34, Hiruzen announces that the Chunin exams will begin on the "first day of the seventh moon," or July 1st. Their first test spans only a few hours, and their second test (immediately after) spans 120 hours, or five days. A month elapses between the preliminaries and the finals (Chapter 88), so, roughly estimated, the Chunin exam final to takes place on August 6th. In the aftermath, Naruto masters the rasengan with Jiraiya over a span of roughly two weeks while retrieving Tsunade. With travel time, Tsunade likely returned at the end of August. Since only a short time elapses between Tsunade becoming Hokage and Sasuke leaving the village, but enough time to do Lee's surgery and for Kakashi to complete an S-rank mission, I estimate the Valley of the End fight to take place in the first week of September. There is a three month gap between Chapters 237 and 238, leaving Part I ending off at December. (Notably, the Sand siblings are seen leaving Konoha after this three-month time skip.)
• Known conflicts: Konoha v. Suna and Oto (Orochimaru's shadow reign of Fourth Kazekage)
• Year 78-81: Karatachi Yagura dies in battle; Sanbi dissipates and is forced to re-articulate itself; Terumi Mei becomes Fifth Mizukage
• Characters: Mei age 28-31
• Notes: When Zabuza defects from Kiri, it is after he has tried to kill the Mizukage of "Blood Mist Village," Yagura, and Kakashi points out in Chapter 30 that Zabuza is raising funds for a "second attempt." This statement suggests that Yagura is still alive as of the Land of Waves arc. However, by Chapter 317, the Sanbi exists as an entity separate from Yagura and the current Mizukage is revealed to be Mei in Chapter 454. This suggests that Yagura died in battle, or else Kiri would have likely made a new jinchuriki after his death. Yagura's age at this time is unknown, but by the end of Part I, he would have been ruling as Mizukage for at least 20 years, as Mei was a participant in the Blood Mist graduation exam (Sasuke Shinden Chapter 1).
• Year 78-81: Orochimaru explores ruins for the Uzumaki clan's documents in Konoha and possibly Uzushio; at some point prior to this, the Uzumaki Noh Mask Hall falls into disrepair
• Characters: Orochimaru age 51-54
• Notes: In Chapter 619, Orochimaru states that he researched the ruins and scattered documents of the Uzumaki clan since he lost his jutsu in battle to the Reaper Death Seal, and in Chapter 618 is shown to be familiar with the Uzumaki Noh Mask Hall on the outskirts of Konoha. An Uzumaki gravestone accompanies the dialogue, though it is not clear if Orochimaru's research is limited to Konoha or if it extends to the ruins of Uzushio.
• Year 79: Inuzuka Kiba, Aburama Shino, Hyuga Hinata, Haruno Sakura, Yamanaka Ino, Akimichi Choji, Rock Lee, Hyuga Neji, Tenten, Gaara, Kankuro and Temari become Chunin
• Characters: Gaara age 13; Kiba, Shino, Hinata, Sakura, Ino and Choji age 14; Lee, Neji and Tenten age 15; Kankuro age 16, Temari age 17
• Notes: According to the Third Data Book, all of Team 8, Sakura, Choji, Ino become Chunin at the age of 14. As Team 10′s third member Shikamaru was already a Chunin and Sakura was without her teammates, Sakura would be their team alternate, which is supported by the anime as well. Lee, Tenten and Neji are one year older and become Chunin at age 15. Kankuro becomes a Chunin at age 16, and he is two years older than the rookies. Temari becomes a Chunin age 17, and she is three years older than the rookies. Including Gaara's promotion in these exams is in contradiction with the Third Data Book, which states that his Chunin promotion age is 14, however, this issue is likely due to the consistent conflating of Gaara's age with the rookies in Part II. Here, I've chosen to prioritize the likelihood of Gaara taking the exams with his teammates and siblings.
• Year 79-80: Gaara becomes Fifth Kazekage
• Characters: Gaara age 13-14
• Notes: In Chapter 247, the Suna council refers to the village's power as having stabilized, "over the past few years." It follows that stabilization would mean they already had a Kage as their village leader, so Gaara becoming Kazekage likely took place at least one year prior to Part I. It is unclear what structure Sungakure's leadership took after Rasa's death but before Gaara took up the title, but there are 11 other council members seen in Chapter 247, so it is possible they acted as a coalition until such time that one of the Kazekage's children was willing to act as Kazekage.
• Year 80: Temari, Kankuro and Neji become Jonin
• Characters: Neji age 16; Kankuro age 17; Temari age 18
• Notes: According to Chapter 247, by the events of Part II, Neji, Kankuro and Temari are already Jonin, which suggests they became Jonin in the year following their second Chunin exams.
• Year 81: Events of Part II inc. Fourth Shinobi War; Sasori, Chiyo, Nii Yugito, Chiriku, Sarutobi Asuma, Kakuzu, Uchiha Itachi, Deidara, Jiraiya, Uzumaki Nagato, Konan, Hoshigaki Kisame, Shimura Danzo, Yamanaka Inoichi, Nara Shikaku, Hyuga Neji and Uchiha Obito all die
• Characters: Gaara age 15; Rookie 9 age 15-16; Team Gai age 16-17; Suigetsu and Karin age 16-17; Kankuro, Kurostuchi and Jugo age 18; Temari and Deidara age 19; Itachi age 21-22; Orochimaru and Jiraiya age 54; Yamato age 26-27; Kakashi age 29-30; Yugito age 29; Chiriku, Asuma and Obito age ~31; Kisame age 32; Nagato, Konan and Sasori age 35; Inoichi and Shikaku age 41-42; Danzo and Chiyo age 73; Kakuzu age 91
• Notes: In Part II, Naruto comes back when the Chunin exams are in the midst of important preparations, presumably also scheduled for July (though they do take place biannually). Assuming Temari's visit to Konoha is among the last of the preparations for the exam, Naruto returns to Konoha sometime in late June (close to the two-and-a-half year gap that's stated in ep. 1 of Shippuden). The Kazekage rescue mission arc takes place over roughly six days. The Tenchi bridge mission takes place after an additional ten days. The Akatsuki suppression mission takes place immediately after over roughly ten days (two days of rasenshuriken training, three days each to seal the Nibi and Sanbi, and an additional 24 hours + travel time for Team 7 to join Team 10). With these missions in mind, it can be estimated that the first three arcs to conclude at the end of July. Though it's less clear how much time elapses during the subsequent arcs (from the Itachi Pursuit mission onward) at the climax of the war in Chapter 643, Obito notes that it is Naruto's birthday, on October 10th, marking the approximate end date of the war.
• Elaboration: Notably, this has to be October of the same year given that Kurenai is at least two months pregnant by the end of the third arc (marked by at least one month to become aware of it, and the aforementioned month of missions), and gives birth to Mirai in the fall after the war. Gaara and Naruto are both noted to be 17 by the end of the war but both are at least 1 year younger than Neji so it is presumed that any statements making their ages equivalent are inaccurate; it is also possible that those ages may apply in Chapter 699, which has a time-skip of several months to a year.
• Known conflicts: Allied Shinobi Forces vs. Madara and Obito (Fifth Hokage/Fifth Mizukage/Fifth Kazekage/Fourth Raikage/Third Tsuchikage's reign)
• Year 81 (Fall, likely late November): Sarutobi Mirai is born
• Characters: Kurenai age 31
• Notes: As Kurenai falls pregnant in the spring preceding the war, Mirai is born in autumn shortly after the war ends.
• Year 81-82: Hatake Kakashi named Hokage, Sasuke is pardoned
• Characters: Kakashi age 30; Sasuke age 16
• Notes: According to Chapter 699, Kakashi is named Hokage shortly after the war and Sasuke is pardoned partly on account of his word. Kakashi does not fully assume the responsibilities and title until almost a year after the war is over (Kakashi Hiden), though it's not addressed whether the pardon is issued before or after Kakashi Hiden, since the novel begins with Kakashi already selected as Hokage and carved on the mountain. For the purposes of this timeline, I will assume the pardon comes pre-Kakashi Hiden.
• Year 83: Nara Shikamaru and Temari begin dating; Akimichi Choji and Karui begin dating; Sai and Yamanaka Ino begin dating
• Characters: Shikamaru, Ino and Choji age 18; Karui and Sai age 19; Temari age 21
• Notes: Shikamaru Hiden takes place before The Last, in which Shikamaru has a date with Temari, so he starts dating Temari two years after the war in the Year 83. Choji and Karui are established as beginning a relationship in the beginning of Sakura Hiden, which is a few months after Shikamaru Hiden. Sai and Ino go out on a date at the end of Sakura Hiden.
• Year 83-85: Uzumaki Naruto and Hyuga Hinata date and get married
• Characters: Naruto and Hinata age 18-20
• Notes: The events of Naruto the Last (canonized in a light novel) and Konoha Hiden establish that Naruto and Hinata get together approximately 2 years after the war. Assuming they get married when they reach the age of majority at age 20, they get married in the Year 85.
• Year 85: Uzumaki Boruto is born
• Characters: Naruto and Hinata age 20
• Notes: It's presumed that Boruto would be born prior to Sarada since his parents get married before hers.
• Year 85: Sasuke returns to Konoha; Sakura and Sasuke go travelling together and marry; Uchiha Sarada is born
• Characters: Sasuke and Sakura age 20
• Notes: Sasuke is still on his journey alone during the events of Konoha Hiden, but as Sarada and Boruto are are approximately the same age, they're both born within this same year or so span. The implication seems to be that Sasuke bringing Sakura on the journey was a marriage proposal in and of itself.
• Year 85: Yamanaka Ino and Sai marry; Inojin is born; Akimichi Choji and Karui marry; Chocho is born; Nara Shikamaru and Temari marry; Shikadai is born; Metal Lee is born
• Characters: Ino, Choji and Shikamaru age 20; Karui and Sai age 21; Temari age 23-24
• Notes: It seems improbable that this many of Naruto's friends would get married and have children in this short a time frame, given that two of these families required the wife's immigration to Konoha. However, in order to be the same age as Boruto and Sarada, all of these children would have to be born around this year.
• Year 87: Uzumaki Himawari is born
• Notes: Himawari is noted to be 2 years younger than Boruto in the Blank Period.
• Year 96: Naruto becomes Hokage; Events of Naruto Gaiden/Konoha Shinden
• Characters: Sarada age 11; Naruto, Sakura and Sasuke age 31; Yamato age 42; Kakashi age 45; Gai age 46; Mirai age 14
• Notes: There is approximately a 13 year time-skip between Chapter 699 and Chapter 700. Thus, this dates Sarada's age at approximately 11 during both 700 and Gaiden, placing those events in immediate succession.
• Year 97: Boruto and Sarada graduate; Team Konohamaru takes the Chunin Exams
• Characters: Boruto and Sarada age 12; Naruto, Sasuke and Sakura age 32; Kakashi age 46
