Sure. For 5-16/18yrs old we work in 12 week terms with a week break in the middle (half term).
So you'd start early/mid September and break up mid/late October, then resume for another 6 weeks and break up for Christmas (two/three week holiday).
The term after Christmas is usually shorter because we have a two week break around Easter which always changes, so sometimes you can be in school for only 5 weeks before another half term holiday, and then 5 weeks again before Easter.
And then 6 weeks, half term, 6 weeks and the Summer break which is 6/7 weeks long.
Uni is slightly different; starts later, finishes earlier and no half terms but Summer and Christmas is longer. Some subjects get reading weeks.
There was probably a much less long winded way to explain that haha
