The Niskayuna Central School District’s 2025-26 school calendar is now available. It was approved by the Board of Education on Tuesday, March 11.
The calendar sets school holidays, vacation weeks and days off for students due to staff development days. Once school and district events and activities are scheduled for the new school year, that information will be added to the district’s website calendar, which is the most up-to-date resource for families and community members.
