Complete month-by-month calendar for San Marcos Public Schools. Every day is color-coded so you can see school days, holidays, and breaks at a glance.
San Marcos Unified School District in 2026-2027 starts later than many August-opening districts on Aug 18, 2026 and extends deeper into June than many nearby calendars on Jun 9, 2027. Most families will start with Thanksgiving Break (Nov 23-27, 2026), Winter Recess (Dec 21, 2026 - Jan 8, 2027), and Spring Recess (Mar 29, 2027 - Apr 2, 2027). Spring Break is placed near the end of March.
The practical planning read is that the later start leaves a longer August planning window before classes resume, the later June finish can shorten the early-summer planning window, Thanksgiving is shown as a full-week break, and winter break is one of the longest no-school stretches on the calendar. That is the part of the calendar most likely to affect care coverage, travel timing, and school-site follow-up.
Outside those major breaks, families should also plan around standalone no-school days and minimum days. Families should scan the supporting schedule details because they include named schedule items such as Student Holiday and Student Holiday (High school only).
The calendar dates on this page are checked against district-published materials; families should still verify late changes against the official district calendar page.
The calendar also marks Minimum Day (Elementary/DPS/LMA) and Minimum Day, which can affect pickup timing and after-school plans even when students are still on campus.
For the 2026-2027 school year, Spring Break runs Mar 29, 2027 - Apr 2, 2027 and reaches the end of March.
The first day of school for San Marcos Unified School District in 2026-2027 is Aug 18, 2026, so the year opens later than many August-start calendars.
San Marcos Unified School District ends the 2026-2027 school year on Jun 9, 2027, giving families a later June finish than the usual May-ending pattern.
Winter Break runs from Dec 21, 2026 - Jan 8, 2027, which gives families a 19-day recess.
