What is the current calendar?

The current calendar that the school operates on is a modified verions of what was once known as the "agrarian" calendar. It was originally created to allow school-aged children a great deal of time off in the summer time to work on the family farm.

Kids start the school year somewhere around labor day, or late in the harvest season and are in school all fall, winter, and spring. They, of course have major holidays off as well as weekends.

Here is a pie chart that kind of demonstrates what the traditional calendar looks like (from the National Association for Year-Round Education).
