The Massachusetts rule

How Massachusetts counts a lost day

Massachusetts requires a 185 day calendar, at least 180 days actually held, and 900 hours for elementary or 990 hours for secondary students. Every day lost through March 31 is made up with full rescheduled days; after March 31, days are made up until 180 or the scheduled 185th day, whichever comes first.
