Hm, different districts then for sure, schools around me start up in the end of January, and then get a delightful break for the new year. (Really, for some schools it's winter break, a couple days back in school, a week off between terms, begin the new year, and then take a week off. Why I don't know, seem like a waste to me). Many new teachers start early Feb because of this.
Also, most of my students started at the end of August for second session, just a couple had it off until the first week of Sept.
