Nobody really knows when Alison went missing , because almost everybody in the barn was in a trance from when Alison was hypnotizing them. Even though Spencer thinks she is to blame she doesn't know either because she followed her out and so did aria, after a few moments (because she wasn't hypnotized), and called their names and Ali and Spencer didn't answer so she went back inside and after a while Spencer came back inside and said
" I can't find her."
Then Emily and Hanna came out of their trance and explained their freaky dreams, both were the same, Ali had fell into a hole and passed out.
Spencer and Aria looked at each other but no one said a word after that. Making that night even freakier and worse.
Off the top of my head, I'd say 1.5-3, not completely sure. Hope this helps. I know that it was 1 when season one started, so from then until season 2 ending was probably 1 year? So that's 2 and then there was 5 months separating season 2 & 3... So yeah, I'd say about 2.5 years! Possibly a little less.
