Interfaith Calendar

This calendar provides a reference point for celebrations, holidays or spiritual engagements that CWU community members may observe during the academic year. The calendar utilizes the Pew Research Center’s data for most commonly observed religious and spiritual practices specific to Washington State. The list provided below is not exhaustive, strives to include as many secular observances, and is intended to be a guide that fosters additional research and reflection. The Diversity and Equity Center welcomes additions and edits by emailing

Students, did you know that you can request reasonable accommodations if an academic responsibility coincides with a religious observance? Senate Bill 5166 states that students must provide faculty written notice within the first two weeks of the quarter with dates noting the request for accommodation.

Thanks to CWU Graduate Student Taylor Roice for helping compile this resource!
