California Schools • 2026–2027

A small calendar shift can create a big sense of belonging.

\n When schools recognize important cultural and religious days, students can observe their traditions without the fear of missing out, falling behind, or being forced to explain why their day matters.\n

Belonging

Students feel seen and respected by their school community.

Academic fairness

Students do not have to miss tests, deadlines, or essential lessons.

Community awareness

Schools become more thoughtful when scheduling key events.

Simple planning

A shared calendar helps administrators, teachers, clubs, and teams plan ahead.
