This is a theoritic timeline I made few months ago for my "who Tobi is" thread, I think I can use it here:
Timeline:
- Consider "Naruto Shippuden Date" as 2000.. Eg: Madara and hashirama fought 80 years ago, so in 1920..got it?
- some years after hashi vs madara (let's say 24 years) 1st Shinobi world War began in..uh, so in 1944. 2nd Hokage died in this war.
- Then after 20 years of peace and 2nd War, in 1964. The Sannin (they were 18 years old) fought Hanzo in this war. And Madara gave Nagato rinnegan 2 years ago, so in 1962
- Inbetween 1967 and 1982: Nagato formed Akatsuki, and Oro joined it
- In 1982 3rd Shinobi world War, lost Obito, Sasori joined Akatsuki
- In 1983 Izuna manipulating Mizukage, and Kisame (he was 16) joined Akatsuki
- In 1984 or 1985 Obito vs. Minato
- In 1991 Uchiha massacre, Itachi joined Akatsuki and became Oro's Akatsuki partner.
Correction:
- the clans war ended in 1920 (say, madara and hashi were 21).
- After 29 years madara attacked konoha in 1949
- In 1946 Tsunade was born (3-4 years before hashi's death) and Hiruzen was 17-18 years old
- In 1952 first shinobi world war and 2nd hokage died.
- after about 20 years of peace, in 1972 second shinobi world war began, and the sannin (they were 26) fought Hanzo. And Nagato was 12.
- In between 1979 and 1984 Nagato formed Ataksuki.
- In 1983 Third war, and Obito joined Madara.
- In 1984 Yahiko died.
- In 1984-1985 obito attacked konoha, and Itachi was 7 years old.
- itachi massacre in 1991 and he was 13.
- in 2000: Naruto is 16 and Tsunad is 54.
