Answer 2

It's after 06.03.2006 and before 06.03.2007.

This is based on the Mclovin id. It says he was born 06.03.1981, you can hear a discussion in the movie of why he wanted the id to say he was 25, and thus the events of the movie have to be occurring in the above mentioned interval of time.

Also the movie was in theaters in 09.14.2007 in the US.
