Note: Revised calendar (v2), approved by the Board 05.11.2026. The district site shows a bot check to this network; its District Instructional Calendars page, read on 2026-09-26 from the district's website content service (the Web Archive's last capture is 2026-07-15), still links this file as the current 2026-2027 calendar through the district's short link aptg.co/pQRdQH (file last modified Aug 11, 2026; same hash). Dates are read from the color-coded grid, which colors breaks and holidays only as 'Holiday'; the names come from the district's online events calendar (saisd.net/events), which lists the same dates: 'Fall Break - No School' Nov 23-27, 'Winter Break - No School' Dec 18 and Dec 21-Jan 1, 'Spring Break - No School' Mar 8-12, Columbus/Indigenous People's Day Oct 12, Good Friday Mar 26 and Battle of Flowers Apr 23. Student holidays for professional development (Sep 18, Oct 9, Nov 6, Jan 5, Feb 5), teacher planning (Jan 4, Mar 29) and parent/teacher conferences (Oct 23, Feb 12) are no-school days for students. Feb 15 (Presidents' Day) and Mar 29 are marked as bad weather makeup days. No school Dec 18 - Jan 5; students return Jan 6. Grading periods: Aug 12-Oct 8, Oct 13-Dec 17, Jan 6-Mar 5, Mar 15-May 26 (40, 41, 39 and 50 student days). Memorial Day (May 31) and June 18 are holidays after the last day. Hot Wells MS, Poe MS and Crockett Academy follow a separate ACE calendar; Tafolla MS, Hirsch Elementary and Ogden Elementary follow a separate Third Future Schools calendar; special campuses have their own calendar.
