Syosset vacations and holidays, 2026-27

Every day with no school for students, from the first day to the last: 16 entries and 35 weekdays in all.

Syosset early release days

The calendar prints no early release days. The last day, June 25, becomes a half day for all students only if the elementary schools have completed at least 180 days of instruction; the district will tell families.

Schools can still send their own early dismissal notices, so watch for those.

Teacher workdays: no school for students

One of the days off is a staff day. Teachers work; students stay home. Plan child care as you would for a holiday.

• Tuesday, Nov. 3: Superintendent's conference day (Election Day)

Makeup days

Snow makeup day (if needed), Friday, May 28 (a school day only if school closes more than three days for weather).

Also worth knowing

• The calendar prints no testing dates. The district directory's month pages mark Syosset High School midterm and Regents weeks and June Regents and final exams.
• Some days off may change: Snow makeup day (closed if not needed), May 28 (Schools are closed if no makeup day is needed; it becomes a school day if school closes more than three days for weather, announced in April 2027).

First and last day of school

The first day of school is Tuesday, Sept. 1, 2026. The last day is Friday, June 25, 2027.

Teachers start sooner. Staff days before school run Aug. 25 to 27.

Grading periods

Elementary and secondary schools are on the same grading schedule. The district prints only each marking period's end date.

What the district notes

• The calendar counts 183 days: 179 instructional days and four superintendent's conference days.
• The middle schools release the schedule for the last week of school, a final exams week, through each building principal.
• Rosh Hashanah (Sept. 12 and 13), Diwali (Nov. 8) and Lunar New Year (Feb. 6) fall on a weekend.

How we checked these dates

We read every date off the district's own calendar twice: once from the PDF's text and once from the image, cell by cell against its legend. Then we checked each one against the district's Calendar page and the 2026-2027 Syosset District Calendar Directory.

Every weekday on this page matches its date. If the district changes its calendar, its page is the final word.
