What is the school calendar: what days are school closed?

Plymouth School of Music is a year round school following a 48 week year calendar; there are 4 weeks a year that we are closed.  We follow a calendar that is almost exactly the same as Plymouth canton schools district and we don't hold lessons  during the following  times; 2 weeks between Christmas and new years, spring break week, Memorial weekend, the week encompassing the 4th of July and labor day weekend.
