The Sachem Central School District 2025-2026 school year runs from September 4, 2025 to June 26, 2026. Sachem is the largest school district on Long Island by student enrollment, serving approximately 14,000 students across 18 schools (11 elementary, 3 middle, 2 high schools, plus alternative programs) in the Holbrook–Lake Ronkonkoma area of Suffolk County. By comparison, neighboring Commack serves roughly half as many students.
Sachem's calendar features a notably long spring recess — running from April 2 through April 10, 2026. This 7-school-day break (Wednesday through the following Thursday) is significantly longer than the standard 5-day spring week at most Long Island districts. This extended break encompasses both Good Friday and Easter, giving families ample time for travel or activities. However, the tradeoff is a slightly later last day of school (June 26).
A unique policy in Sachem's calendar is its "Day of Holy Obligation" designation for Eid al-Fitr (March 20, 2026). Unlike districts that fully close for Eid, Sachem keeps schools in session on this day but prohibits all tests and major assignments. This allows students observing the holiday to stay home without academic penalty. It's a compromise approach that's different from what neighboring districts like Brentwood or Bay Shore do.
The district observes both days of Rosh Hashanah (September 23–24) and Yom Kippur (October 2), which is standard for Suffolk County. The mid-winter recess is a full week (February 16–20), and winter recess runs December 24 through January 2. These align well with most other Suffolk and Nassau districts.
The day before Thanksgiving (November 26) is a half day, and the last day of school (June 26) is also a half day. Election Day (November 4) is used as a Superintendent's Conference Day, meaning students have no school. Regents Exams run June 16–25; with two comprehensive high schools (Sachem East and Sachem North), the exam logistics are a significant calendar consideration for the district's roughly 4,000 high school students.
Given Sachem's Suffolk County location, 2-4 snow days per year are typical. The district is less affected by coastal storms than south shore communities but still sees significant winter weather events. Snow day usage may shift the June end date.

Winter Recess runs from December 24, 2025 through January 2, 2026.
Spring Recess runs from April 2–10, 2026 — a notably long 7-school-day break that includes Good Friday and Easter.
The last day is Friday, June 26, 2026, and it is a half day.
November 26 is a half day. Schools are closed November 27–28 for Thanksgiving.
On certain religious holidays like Eid al-Fitr (March 20, 2026), schools remain open but no tests or major assignments are given. Students observing the holiday can stay home without academic penalty. This is different from districts that fully close for the day.
Sachem's Spring Recess (April 2–10) runs 7 school days, which is 2 days longer than the typical 5-day spring break at most Long Island districts. This extended break covers both Good Friday and Easter, but results in a slightly later end to the school year.
Sachem is the largest school district on Long Island with approximately 14,000 students across 18 schools, including two comprehensive high schools (Sachem East and Sachem North). It's roughly twice the size of neighboring Commack.
