Editorial summary
Student holidays and campus calendar differences
The regular San Antonio ISD calendar runs from Aug. 12, 2026 through May 26, 2027. Student holidays for staff professional development include Sep. 18, Oct. 9, Nov. 6 and Feb. 5. Parent-teacher conference days on Oct. 23 and Feb. 12 are also no-school days for students.
Students are off Oct. 9-12, with staff professional development on Oct. 9 and the Columbus/Indigenous People's Day holiday on Oct. 12. Winter break runs Dec. 18-Jan. 1, followed by teacher planning on Jan. 4 and professional development on Jan. 5; students return Jan. 6. Feb. 15 and Mar. 29 are also reserved as bad-weather make-up days, so either long weekend could be shortened if SAISD activates a make-up day.
Hot Wells Middle School, Poe Middle School and Crockett Academy use the ACE Resource ADSY calendar. Tafolla Middle School, Hirsch Elementary and Ogden Elementary use the Third Future Schools calendar. Those calendars have different attendance dates from the regular district calendar.

About the San Antonio ISD 2026–2027 District Instructional Calendar calendar
Data source
This page uses San Antonio ISD’s official 2026-2027 Instructional Calendar, version 2, approved by the Board on May 11, 2026, plus the district’s instructional-calendar page. The district Board Meeting Schedule supplies the named October or February holidays where the instructional PDF uses a generic holiday label.
How dates are handled
Events preserve the dates and attendance categories shown on the official calendar. Separate holidays, planning days and staff-development days are not merged into new events. Breaks describe longer spans away from school and reference their component events; any bad-weather make-up component remains conditional. Grading-period milestone names are normalized from official boundaries. The noSchoolDayEventIds index contains confirmed no-class or no-student events and excludes conditional make-up dates. Conditional attendance is a normalized interpretation of official make-up designations; the event basis and source labels retain the official evidence.
Updates
Use the calendar assigned to your campus. The regular calendar marks two dates for possible bad-weather make-up instruction; district announcements determine whether students attend. Check the instructional-calendars page for revisions.
