This is a timeline of canon events in the Adventure Time series. To take track of the events in a good way, we need a year 0, in this case, that is the Mushroom War, most specifically, the explosion of the Mushroom Bomb, so the series events happened around 1000 years After Mushroom War (A.M.W.). ~100+ means that is more likely that happened more than 100 years after, in the same way, ~100- means that is more likely that happened less than 100 years after.
