Pre-K classes have their own times on the same page. A decision to release early because of weather is separate from these planned dates, and the district says it can dismiss earlier or later than the standard schedule. See snow days and delayed openings in Greenwich.
Which early release days only apply to some grades?
- August 27 is the Grade 6 and 9 orientation.
- December 8 is K-8 conferences.
- March 8 and March 17 are K-5 conferences.
The other early release days are listed without a grade restriction. If you have a child in a grade the calendar doesn't name, check with the school.
Days that are not early release
Some days off are full closures, not early release. For example, December 7 is a professional learning day with no school for students. See the full 2026-27 calendar for every closure and recess.
Snow days can change the last day
The calendar marks June 22 as the last day for students and says it includes five snow days. Its note says that if more snow or storm days are needed, they will be taken from either the remaining days in June or from the spring recess in April. See snow days and delayed openings in Greenwich.
