Source and scope

About the Katy ISD 2027–2028 calendar

Data source

Dates come from Katy ISD's official one-page 2027-2028 Instructional Calendar, adopted by the Board of Trustees on January 20, 2026, and the district calendar page that hosts the PDF.

How dates are handled

The record includes districtwide student attendance dates, student-and-staff holidays, breaks, campus learning days with no students, semester starts, and districtwide early dismissals. Employee orientation, teacher start dates, staff-only holidays after the student year, and grading-cycle markers are not treated as student events.

Updates

The district calendar page and linked PDF were checked on October 5, 2026. If Katy ISD replaces the PDF, first and last days, break ranges, no-student dates, early dismissals, and printed approval information should be checked again.
