Oh, summer break already? Is it until September or so? Well, here it depends where you are. At school, the holidays are usually like this (varying slightly between different "federal states"):
Xmas (2 weeks from shortly before Xmas until shortly after New Year)
Eastern (2 weeks with Eastern being in the middle)
Summer (6 weeks, the begging varies between end of June and end of July)
Autumn (2 weeks, here the beginning varies between mid-September and mid-October)
But since I'm at university right now, it's simpler:
Spring holidays between mid-February and mid-April and "late summer" holidays between mid-July and mid-October.
This might sound much on the paper (5 months!) but there's usually some stuff to do in those "holidays" as well, like tests, lab periods (which can be up to 6 weeks) etc. It's just that there are no regular lectures in those "holidays".
