If you been searching for “Matanuska-Susitna Borough School District Calendar 2026-2027” then you are not alone.
The school calendar is essential for schools to coordinate and communicate with all of the students and parents of various classes and in different schools. Because of this, a school must maintain a proper calendar that delineates student and non-student days, school and non-school days, as well as the various breaks throughout the year.
This page contains the major holiday dates from the 2026 and 2027 school calendar for Matanuska-Susitna Borough School District in Alaska.

🗓️ Additional Calendar Features & Notes
The district maintains separate calendars for Elementary vs. Secondary (middle/high) schools.
Elementary students have three fewer instructional days than middle/high schools; those days are used for teacher work, professional development, or parent-teacher conferences
Monday late-start schedule is in place (students begin later on Mondays) to allow for teacher development.
Schools have legally required instructional hours; Mat-Su uses a waiver that allows counting hours (rather than just days) for compliance.
There are built-in “buffer days” for snow/emergency closures
