I've got a question for u guys, when is ur summer vacation(the dates of beginning and ending) and other vacations(like christmas vacation), cuz i've come to the impression that over here we got loooots of vacation compared to some other countries, also there is a difference between college and high school. If there is nothing mentioned the vacation is for both, here are my vacations(im in college, no longer high school) :
-summer : 1sth july - 1september(high school)/ 22th september(college,it can be different a couple of days from year to year)
- in high school : a whole week somewhere in october
- christmas vacation : two weeks which include christmas and new year (but in college there's only time to study and almost no time to go out

)
- in college : the first week of february(after my exams who begin somewhere around 6january and last until 31th jan)
- in high school a week at the end of february
- two weeks of easter vacation(again to study if u are in college)
thats about it, there are also some holidays and stuff but i left them out cuz it would be too detailed, but if u add it all up well u could say we have about 4months of vacation
