About 8 or 9 weeks where I was -- they got out around mid June and returned just after the middle of August to a very hot school. Some states got more iirc and some school districts now do year round school. There were no mid term breaks that schools get in Ireland and Britain but a few national holidays as well as some religious hols (two days plus a weekend at the end of Nov. for Thanksgiving, two weeks at Christmas, a week in Spring/Easter, Good Friday, sometimes Rosh Hashana, Labour Day, Memorial Day, President's Day, Martin Luther King Jr. Day, Columbus Day, a day off for the parent teacher meetings). I don't think they needed the make up days either, but the state required that there be a certain number of days in the school year. You could phone your DCs in sick.
