Katy ISD's 2026-27 year runs Wednesday, August 12, 2026 to Wednesday, May 26, 2027, with a long weekend of fall break (October 9–13), the whole of Thanksgiving week, two weeks at winter break and a week at spring break (March 8–12). The days that catch parents out are the five Campus Professional Learning Days with no students, every one a Friday or a Monday, the Campus Day with no students on January 4, and the two early dismissals that close each semester.
Below is the district's dated "Calendar Highlights" list, every line, with Katy ISD's own wording kept intact — then how to get it onto your phone next to the team schedules.

The PDF is stamped "Approved by the Katy ISD Board of Trustees on January 20, 2026", and the district's news release from that date explains why: the Board amended the 2026-27 calendar to add a fall break, October 9–13, 2026, after community feedback gathered through a district survey. Friday, October 9 through Tuesday, October 13 is a five-day weekend; students return Wednesday, October 14, which is also the day the second elementary grading cycle begins. The release also notes the early graduation option for seniors was removed in this revision.
Five Campus Professional Learning Days are marked "• No Students": Friday, September 18; Friday, October 23; Monday, November 2; Friday, February 12; and Friday, April 9. A sixth, Monday, January 4, is a "Campus Day • No Students", so students return from winter break on Tuesday, January 5, the first day of the spring semester. Note the long weekends they create: February 12 runs into the February 15 holiday, so students are out Friday through Monday.
Friday, December 18, 2026 is "Early Dismissal and End of Semester" and Wednesday, May 26, 2027 is "Early Dismissal and Last Day of School". The PDF does not state a dismissal time; that depends on your campus's bell schedule.
The Days of Instruction table totals 172 days for both elementary and secondary: 81 in the fall semester (August 12 – December 18) and 91 in the spring (January 5 – May 26). Elementary runs four grading cycles (40, 41, 46 and 45 days) and secondary runs six (26, 26, 29, 27, 31 and 33 days). The dated list names only the cycle starts that fall mid-semester (secondary: September 21, November 3, February 16 and April 12; elementary: October 14 and March 22); the first cycle of each semester has no line of its own.
The PDF's bad-weather statement reads: "This calendar contains enough minutes to cover two bad weather days." It names no make-up days. The "Holiday • Staff" entries (July 3, 2026, May 31, 2027 and June 18, 2027) and the "District and Campuses Closed to the Public" days (July 1–2, 2026) fall outside the student year and are listed above only because the document lists them. The PDF also notes that 238-day employees will need to work eight additional days.
The quick way: create a free Schedule Caddie account from this page and the 2026-27 calendar above is already on it as your own schedule — the version we verified on November 9, 2026, yours to edit. If Katy ISD revises the calendar later, upload the new version and you see exactly which days changed before approving them.
Doing it yourself, or a different district:
The district publishes this calendar as a document, not a feed you can subscribe to. Schedule Caddie reads that document for you: download the 2026-27 calendar from the district (the source link above), upload it as a PDF, PNG, or JPG up to 10MB, and it pulls out the no-school days, breaks, early releases with their dismissal times, teacher days, and the first and last day of school.
Nothing is saved until you have looked at it. Every day it found shows up as its own row with the date and label, you uncheck what you don't want and fix anything it misread, and only then does it land on your family calendar, color-coded as School so a holiday Monday reads differently from a 4pm practice. Team schedules you have added as calendar links keep refreshing on their own; the school year sits beside them.
Either way it travels like anything else on your Schedule Caddie calendar: subscribe to your Schedule Caddie link in Google Calendar, Apple Calendar, or Outlook and the school days come along.

The first day of school is Wednesday, August 12, 2026 ("First Day of School and Fall Semester"). The last day is Wednesday, May 26, 2027, which is also an early dismissal. Teachers start July 31 and have a Campus Day on May 27 after students leave.
Fall break is Friday, October 9 through Tuesday, October 13, 2026, for students and staff. It was added to the 2026-27 calendar by a Board amendment approved January 20, 2026. Students return Wednesday, October 14.
Spring break is Monday, March 8 through Friday, March 12, 2027, for students and staff. Two weeks later, Friday, March 26 through Monday, March 29 is a "Holiday • Students and Staff", a four-day weekend.
Thanksgiving is the whole week: Monday through Friday, November 23–27, 2026 is a "Holiday • Students and Staff". Winter break runs Monday, December 21, 2026 through Friday, January 1, 2027, followed by a Campus Day with no students on Monday, January 4; students return Tuesday, January 5.
Two: Friday, December 18, 2026 (end of the fall semester) and Wednesday, May 26, 2027 (the last day of school). The calendar does not give dismissal times.
