Note: Trustees unanimously approved amendments to the 2026-27 Academic Calendar on Feb. 19, 2026 (first day moved to Aug. 19; staff development days on Oct. 9 and Feb. 12), per the district's board brief of Feb. 26, 2026 (the amendments also removed a Sept. 4 staff development day); this version is marked 'Updated 02-04-2026' and its English page is identical to the calendar in the Feb. 19 board packet (item H4). Round Rock ISD calls the Thanksgiving week (Nov. 23-27) 'Fall Break'; there is no separate fall break. Dec. 17 is the last day of classes before winter break (Dec. 18 is a teacher work day); Jan. 4 is a staff development day and students return Jan. 5. The calendar states 170 instructional days (based on a 440-minute day). Memorial Day (May 31) is after the last day of school. The calendars page was read via a Web Archive capture of Aug. 13, 2026 (the live site shows a bot check); the PDF was downloaded directly from the district's file host. The district's Google Calendar feed (linked on the Calendars page) lists the same no-school days and names Dec. 21 - Jan. 1 'Winter Break' (the PDF lists Jan. 1 separately as New Year's Day).
