When does US summer lazy season end?

[Ms Naughty]

Hi guys
So it's bloody freezing here but you're at the height of summer there. Lots of you have cut back on work and are enjoying the warm weather.

I'm wondering: when does everybody over there get back into it? It seems to start on July 4... how long is everybody's personal summer slowdown? And schools don't go back until September or something, right?

I just realised I've never really known.

In Australia we hit Christmas and that's it, everybody is useless until about January 3, or a week after that.
