I'm just taking stock of all the timeline weirdness that has cropped up in the series. If you can think of any more or throw in some corrections, then shoot.
Hiruzen becoming Hokage
Hiruzen is said to have become Hokage 31 years before the end of the Fourth Shinobi War. As he died around 4 years ago at age 69, he would have been around 42 years old at this time. But the Sannin would have been 24 years old and they first graduated at 6 years old, 49 years before the end of the war, and Hiruzen was visibly older than when he first became Hokage. We are also told that Dan died 31 years ago where we could see that Hiruzen was even older than before.
Orochimaru leaving Akatsuki
Orochimaru is said to have left Akatsuki 7 years before the timeskip. He left because he was defeated by Itachi who was a member at the time but Itachi would have only been 11 years old at the time. Yet he was able to defeat Orochimaru effortlessly, looked far older than a pre-teen and was shown as a member of Akatsuki even though it was 2 years before the Uchiha Massacre and his flight from the village.
FYI, Itachi became a chuunin at 10, joined ANBU half a year later, and became ANBU Captain at 13.
He should have killed Orochimaru after leaving Konoha at 13-14 years old.
Sasuke leaving Konoha
Based on the change in the moon, Sasuke must have left Konoha around a week or so after the Sound Four defeated him and made their offer.
The night the Sound Four attacked Sasuke.
The night Sasuke left Konoha.
The problem with this is that it meant the Sound Four were willing and able to hide in enemy territory for an entire week undiscovered, and Orochimaru was willing to wait that long despite the pain he was in and even ran out of time as Sasuke finally came to Oto.
And it means that Sasuke's decision wasn't an impulsive decision born from just waking up from Itachi's Tsukuyomi, from apparently being surpassed by Naruto and his Rasengan and from just getting his ass handed to him by the Sound Four. Instead of had the whole week to come to a decision while nothing else happened. This issue isn't too bad but it paints Sasuke's decision in the different light.
Another problem is that Rock Lee decided that he would have his surgery on the same night the Sound Four appeared but he didn't actually have the surgery until the Sasuke Retrieval Mission was underway a week later. And then he went chasing after him after his surgery on the same day and fought Kimimaro.
Three Years to Rescue Sasuke
Jiraiya tells Naruto that Orochimaru can't steal Orochimaru's body for at least 3 years. And this discussion took place on the same day the retrieval mission occured and Orochimaru had swapped his body, as far as we know. So 3 years from that day.
Between the final chapter and penultimate chapter of Part 1, there is a time skip of 3 months as Sakura only started training with Tsunade after the mission failed. Naruto's still in the village and everyone has recovered, so that 3 months out of the 3 year time limit.
After that, Naruto spent 2 and a 1/2 years on his training trip. This means that they only have three months or so to rescue Sasuke.
However Sakura states that they still have half a year to rescue Sasuke.
In the Rescue Kazekage Arc it took 3 days to reach Suna from Konoha, the time between to reach Akatsuki's hideout and Team Seven had their reunion 10 days from then. Yet this time Sai states there almost a 1/2 year left, likely taking into account the time from when Naruto return to this mission.
So the 3 months wasted pre-timeskip have been completely ignored. On top of that, when Orochimaru's time restraint comes to an end and he's able to use his jutsu to possess Sasuke, Naruto and Sakura are showing no urgency or worry over the end of the time limit.
The Second Chuunin Exam
Before the Tenchi Bridge Mission, Shikamaru is sorting out the entrants for the upcoming Chuunin Exams. With the reunion taking place around 7 days after Team Kakashi returns from Suna, it's unlikely that the mission even lasted 2 weeks.
But once they return from their failed mission to retrieve Sasuke, those Chuunin Exams are already over. Either implying that more than a month has passed since Naruto's last conversation with Shikamaru or that these Chuunin Exams are drastically different from the previous ones without any mention of it.
Tsunade being a Granddaughter
Hashirama seemed to have married Mito after Konoha was established, around 67 years before the end of the fourth war according to the fourth databook. Yet Tsunade was 55 years at the end of the fourth war which meant that she would have been born only 12 years after those two had gotten together, despite being their granddaughter.
Obito meeting Yahiko
Presuming that Yahiko would have been the same age as Nagato and Konan who died at age 35, Yahiko died 20 years ago at the age of 15 according to the fourth databook. Yet Obito is only 31 years old at the end of the war - 4 years younger - and met Yahiko before he died. But 20 years ago Obito would have been 11 years ago yet he met Yahiko as "Madara" some time after the events of the Kakashi Gaiden when he would have been around 13 years old.
Honorary Mentions
- Part 2 covering around 1 and a 1/2 years in total.
- The Konoha 12 (and everyone else) is a year older in the second databook than they are in the first regardless of when their birthday is. Including Hiruzen who died the same day the first databook ended and the second started.
- Whenever the hell Orochimaru left Konoha. Presumably before the Kyuubi Disaster but canon is unclear and the anime says fuck that.
- Anko apparently receiving the curse seal when Juugo was only a toddler. I justified it as being a prototype.
- Sasuke stretching my sod by spending two weeks in a coma and then matching Lee's unweighted speed, had identical taijutsu, learning lightning nature transformed and the Chidori in the next two weeks.
- Whenever the hell Hashirama died, especially when he lived long enough to know his granddaughter.
