It takes place in 2012. Dipper and Mabel's birthday is the last of summer in 1999, the last day of summer is one week away in the show as of "Dipper and Mabel vs. the Future." Therefore, their ages are 12 according to "The Inconveniencing" from 2011 (hope I got the episode right). At the end of the summer, they will turn 13. Therefore, the show takes place in 2012.
