The first day of New York City public school will be unusually late this fall, according to the official 2026-27 school year calendar released Tuesday — forcing families to scramble for child care at the end of summer break.

Students are set to return to the classroom Sept. 10, the calendar confirmed — a delayed first day that while inconvenient, was not entirely unexpected. The first day of school is normally the Thursday after Labor Day, which, falling on Sept. 10, is also late this year.

In practice, working parents will have to shell out for another week of summer camp — if programs offer it — or make other child care arrangements. Some parents, particularly moms, will inevitably face job disruptions.

Mamdani, asked about the cost to families at an unrelated news conference on Tuesday, said the late first day came out of negotiations between the school system and the teachers union, the United Federation of Teachers. The UFT advocates that its members, who report to work two days before the first day of school for students, return from summer break after Labor Day.

“We take very seriously the responsibility we have to parents across the city,” Mamdani said, pointing to his efforts to expand free child care year-round, at an education-related event in Boerum Hill, Brooklyn.

“We are looking at the ways in which the city can make it easier for parents to raise a child in this city.”

State law requires that districts offer 180 school days, including a few professional development days for teachers. As the city’s school system has added new official holidays, that minimum has been increasingly difficult to reach, resulting in late last days of the school year and all but ending the traditional snow day. (In the event of inclement weather, schools typically pivot to remote learning, though the state granted the city a waiver last winter for the first time since the COVID-19 pandemic.)

During the 2026-27 school year, the last day of school will fall on a Monday, June 28, which will likely see poor attendance as some parents yank their children from the classroom for summer camp and family vacations.

To help avoid extending the school year and cutting further into summer break, Election Day, on Nov. 3, will be a remote school day. Students typically have Election Day off from school.

The school calendar’s architects also had the benefit of a number of school holidays falling over weekends, including Rosh Hashanah, Diwali and Juneteenth. Lunar New Year overlaps with the midwinter recess in February, and an extended spring recess in April will give schools the days off for Passover.
