Taki lives in 2016. Mitsuha lived in 2013, before she died. That changed when Taki drank the sake that contained half of her soul. Suddenly, she revived in 2013, causing a butterfly effect. Taki is 3 years younger than Mitsuha normally. But when they met at the volcanic crater during twilight, they were both 17. According to the movie, multiple worlds can collide during twilight.
