OUSD Calendar 2026-27: Winter Break Dec. 21 to Jan. 4

The Oakland Unified School District (OUSD) 2026-27 calendar has winter break from Dec. 21, 2026 to Jan. 4, 2027, spring break from Monday, March 29 to Friday, April 2, 2027, and a last day of instruction on Thursday, May 27, 2027, according to the district’s “2026-27 School Calendar” PDF. Students return Wednesday, Jan. 6, after a Professional Development (PD) day on Jan. 5. A table of every no-school day, a comparison with last year and a printable are below.

The first day of school was Monday, Aug. 10, 2026, the district’s calendar page says. The OUSD board approved the 2026-27 calendar on Wednesday, Jan. 22, 2025, in the same vote that approved 2025-26 and 2027-28, according to a district newsroom post dated Jan. 24, 2025. The PDF carries no date.

Return days are our reading of the calendar. The district prints “First Day of Spring Semester” for Wednesday, Jan. 6; the other return days are the next weekday it does not list as a day off.

Break	District’s dates	Days in a row off, with weekends	Students return
Thanksgiving Break	Mon.-Fri., Nov. 23-27, 2026	9 (Sat., Nov. 21 to Sun., Nov. 29)	Mon., Nov. 30, 2026

The district marks the Thanksgiving, winter and spring breaks “some Child Development Centers open”, so some Child Development Centers stay open when classrooms are closed. The district lists Friday, Dec. 18 as the end of the semester for middle and high schools. The December 2026 printable calendar shows the weeks, and other districts’ dates are in our winter break 2026 roundup and Thanksgiving break roundup. The San Francisco Unified calendar lists that district’s dates.

Before the first day, the calendar lists a PD day on Wednesday, Aug. 5, a collaboration and work day on Thursday, Aug. 6 and a teacher work day on Friday, Aug. 7. After the last day, it lists a teacher work day on Friday, May 28, Memorial Day on Monday, May 31, Juneteenth observed on Friday, June 18 and Juneteenth on Saturday, June 19. The calendar’s legend line for Farmworkers Day says only “(in Lieu)”, so this story does not say what it replaces.

How does OUSD 2026-27 compare with last year?

The district’s January 2025 post lists the 2025-26 dates. They are last year’s, shown here for comparison.

	2025-26 (last year)	2026-27
First day	Mon., Aug. 11, 2025	Mon., Aug. 10, 2026
Winter break	Mon., Dec. 22, 2025 to Mon., Jan. 5, 2026 (listed with a PD day)	Mon., Dec. 21, 2026 to Mon., Jan. 4, 2027, then a PD day on Jan. 5
Cesar Chavez Day and spring break	Fri., April 3 to Fri., April 10, 2026	Farmworkers Day Fri., March 26; Spring Break Mon.-Fri., March 29 to April 2, 2027
Last day	Thu., May 28, 2026	Thu., May 27, 2027

Winter break starts one calendar date earlier this year, Dec. 21 instead of Dec. 22, and both begin on a Monday. The spring block starts eight days earlier: Friday, March 26, 2027 against Friday, April 3, 2026. The 2025-26 label reads “Cesar Chavez Day & Spring Break”, while the 2026-27 PDF lists Farmworkers Day and Spring Break as two entries. The March 2027 printable calendar shows the week.

What about the OUSD 2027-28 school year?

Montera Middle School’s academic calendar page lists the first day of 2027-28 as Aug. 9, 2027 and the last day as May 24, 2028. The same page lists the last day of 2026-27 as May 27, 2027, which matches the district PDF. This story does not use other dates from the 2027-28 calendar.

What the OUSD calendar does not list

The 2026-27 calendar prints no minimum days or early-release days. It lists the end of marking periods (Sept. 17, Oct. 30, Dec. 18, Feb. 19, March 25, April 9) and trimesters, with a note that “some alternative education high schools operate on different grading calendars.” Those are grading dates, not days off. For a school-specific schedule, check your school’s page on the district site.
