finn is currently 17 years old as revealed in the season 10 episode "seventeen". at the beginning of the series, finn was a 12-year-old boy who is supposedly the only known human in the land of ooo. during the episode "mystery train", finn turned 13; it has been stated that the episode's air date (march 14) is finn's birthday. after season 3 ended, pendleton ward stated in an interview that finn was 14. finn was 15 years old in the second half of season 5, according to adam muto. in the season 6 finale, "the comet", finn reveals that he has reached 16 years of age. and finally, during the episode "seventeen", finn turned 17 years old. this means that unlike in many other cartoons where characters stay the same age or age through time skips, in "adventure time", time passes mostly regularly (from seasons 1 to around 5). however, at some point, the rate time passed in the show became slower and it stopped being in real-time, as finn is only 17 by the ending instead of 20. due to jeremy shada, finn's voice actor, going through puberty, finn's voice is noticeably deeper in the later seasons, compared to his childlike voice in the first four seasons.
