The school calendar is essential for schools to coordinate and communicate with all 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 school calendar for Duarte Unified School District in California.
