If you've got a child in public school, you live by the school calendar. Many local NYC preschools follow the public school schedule too. The New York City Department of Education's calendar for the 2019-2020 school year was (finally!) just released, and you'll want to bookmark it now, for next year's family vacation plans and, if you're really on the ball, to help with advance planning for school break camp coverage.
With the exception of the occasional unplanned snow day or case of the sniffles, these are all of the dates you can count on your kiddos being out of school during the 2019-2020 school year.
