This has absolutely nothing to do with the Age of Aquarius (come to think of it, few things do), but I have no idea where this was taken, only that it was the afternoon of January 10th.
BREAKING EDIT: The night after I posted this (i.e. tonight), I was watching The 40-Year-Old Virgin on TV. I hadn't seen the whole thing, and at the end, the whole freaking cast runs around singing "Age of Aquarius." Joy of juxtaposition or WHAT?!
