Katy ISD Calendar 2026-27: Thanksgiving, Winter Break and Spring Break

Katy Independent School District (ISD) has no school from Monday, Nov. 23 through Friday, Nov. 27, 2026, according to its “Instructional Calendar 2026-2027”, which the Katy ISD Board of Trustees approved on Jan. 20, 2026. Winter break runs Monday, Dec. 21 through Friday, Jan. 1, and spring break is Monday, March 8 through Friday, March 12, 2027. The last day of school is Wednesday, May 26, 2027. Fall break (Oct. 9-13) has already passed, so Thanksgiving week is the next break.

Katy ISD break dates for 2026-27

The district’s calendar labels the breaks “Students and Staff”. The weekday counts and return days in this table are our reading of the PDF.

Break	Dates	Weekdays off	Back in class
Fall break (past)	Fri., Oct. 9 to Tue., Oct. 13, 2026	3	Wed., Oct. 14
Thanksgiving week	Mon.-Fri., Nov. 23-27, 2026	5	Mon., Nov. 30
Winter break	Mon., Dec. 21, 2026 to Fri., Jan. 1, 2027	10	Tue., Jan. 5, 2027 (Jan. 4 is a campus day with no students)
Spring break	Mon.-Fri., March 8-12, 2027	5	Mon., March 15
Easter-weekend holiday	Fri., March 26 to Mon., March 29, 2027	2	Tue., March 30

Thanksgiving Day itself is Thursday, Nov. 26. The Friday-to-Monday holiday in late March is printed on the PDF as “Holiday • Students and Staff” with no name; it falls on the Friday and Monday around Easter. The calendar does not mark Veterans Day, Nov. 11, as a holiday. Mark winter break on the December 2026 calendar and spring break on the March 2027 calendar.

The district’s Jan. 20, 2026 release, “Katy ISD Board of Trustees Approves Fall Breaks for 2026-2027, 2027-28 Instructional Calendars”, says the board added an October fall break to the calendar.

Is the first day of spring semester Jan. 4 or Jan. 5 in Katy ISD?

It is Tuesday, Jan. 5, 2027. The PDF lists Monday, Jan. 4 as “Campus Day • No Students” and Jan. 5 as “First Day of Spring Semester”. Students are off for 17 days counting weekends, from Saturday, Dec. 19 to Monday, Jan. 4. The last day before winter break is Friday, Dec. 18, an early dismissal day that the calendar marks as the end of the semester.

Which Katy ISD days off do summaries miss?

The calendar has more no-student days than the named breaks. Five Fridays and Mondays are “Campus Professional Learning Day” with no students, and each one lengthens a weekend.

Date	Weekday	What the calendar lists	Days off counting weekends
Sept. 7, 2026	Monday	Holiday (Labor Day by date; past)	3, Sat. Sept. 5 to Mon. Sept. 7
Sept. 18, 2026	Friday	Campus Professional Learning Day (past)	3, Fri. Sept. 18 to Sun. Sept. 20
Oct. 23, 2026	Friday	Campus Professional Learning Day	3, Fri. Oct. 23 to Sun. Oct. 25
Nov. 2, 2026	Monday	Campus Professional Learning Day (past)	3, Sat. Oct. 31 to Mon. Nov. 2
Jan. 18, 2027	Monday	Holiday (Martin Luther King Jr. Day by date)	3, Sat. Jan. 16 to Mon. Jan. 18
Feb. 12-15, 2027	Friday, then Monday	Campus Professional Learning Day, then Holiday (Presidents Day by date)	4, Fri. Feb. 12 to Mon. Feb. 15
March 26-29, 2027	Friday, then Monday	Holiday; the district does not name it	4, Fri. March 26 to Mon. March 29
April 9, 2027	Friday	Campus Professional Learning Day	3, Fri. April 9 to Sun. April 11

The Feb. 12 and Feb. 15 pair is the easiest to miss: a four-day weekend sits between two ordinary school weeks. Our printable school-year calendar page and the printable below mark each of these days.

How does Katy ISD spring break 2027 compare with other Houston-area districts?

Katy shares March 8-12, 2027 with Houston ISD and Fort Bend ISD. Cy-Fair ISD and Conroe ISD break a week later. That matters for families with children in two districts.

District	Spring break 2027	First day	Last day
Katy ISD	March 8-12	Aug. 12, 2026	May 26, 2027
Houston ISD	March 8-12	Aug. 10, 2026	May 28, 2027
Fort Bend ISD	March 8-12	Aug. 11, 2026	May 26, 2027
Cy-Fair ISD	March 15-19	Aug. 12, 2026	May 27, 2027
Conroe ISD	March 15-19	Aug. 12, 2026	May 27, 2027

Each row comes from that district’s own 2026-27 calendar PDF, listed under sources. See our Houston ISD calendar story and Cy-Fair ISD calendar story for those districts’ other days off, and the spring break 2027 roundup for more districts.

How many school days and bad weather days does Katy ISD have?

The calendar counts 172 instruction days: 81 in the fall semester and 91 in the spring. It says it has “enough minutes to cover two bad weather days”, and it lists no make-up dates.

What are the first and last days of the 2026-27 school year?

Students began on Wednesday, Aug. 12, 2026, listed as “First Day of School and Fall Semester”. The last day is Wednesday, May 26, 2027, an early dismissal day. The PDF does not print grading-period dates, so we do not list them.

What does Katy ISD’s 2027-28 calendar look like?

The same Jan. 20, 2026 release says the board adopted the 2027-28 calendar too. Per the release, the first day is Aug. 11, 2027, fall break is Oct. 8-12, 2027, spring break is March 13-17, 2028, and the last day is May 24, 2028.
