Source and scope

About the San Antonio ISD 2027–2028 District Instructional Calendar calendar

Data source

This page uses San Antonio ISD’s official 2027-2028 Instructional Calendar, version 2 dated January 30, 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.
