This calendar includes a listing of holy days / holidays, heritage, history and awareness months. This document is meant to serve as a resource and tool to help promote awareness and share information. This is not exhaustive of all major holy days in every religious tradition and some variances of dates will exist due to regional differences. Our CU community is encouraged to find opportunities to learn about and honor identities and cultures year-round as a part of our on-going commitment to advancing inclusive excellence.
