Second Shinobi World War

<p>This is the first time I've ever used my wiki account on this particular wiki website, so I'm sorry if I make a mistake or two in this, but I just would like some pointers about the browse data stuff for characters. I know that a seeming majority of users here decided that this wiki didn't need gender categories and all that, but I don't think I'm using the browse data right. I've been trying to find characters that fit under Kirigakure, for example, and so far, no luck. I'd try to go into detail, but while I'm not unintelligent, that doesn't mean I'm good at describing stuff occasionally. </p><p>Other than that, I'd also like to ask if this wiki can have a timeline article like most other wikis do. I reckoned that the Naruto verse didn't go into detail into an actual calendar like Gundam, or Code Geass for some examples, but if the One Piece wiki an manage the pattern of events in that manga/anime's history, I don't see how the Naruto wiki can be different. I'm just saying. I'll be alright, if a large majority here decide against it. </p>

<p>I've been trying to figure out how long the length of time is between each world wars. I know between the 1st and 2nd there was twenty years but the gaps between 2 and 3, and 3-4 are not clear. The thing that makes this hard for me to figure out is how old the characters are. For example, Nagato's parents died during the 2nd war and they were trained by Jiraya around this time as well. Yet he's around 35 years old at the time of his death. The thing that makes this weird is Kakashi is like 30-31 at this time same goes for Obito. So can someone help clear this up for me. How long of a gap was there between the 2nd and 3rd wars, and 3rd to 4th wars. </p>
