Inclusive Holiday/Interfaith Observation Calendar

Our HGAR community represents a wide range of ethnic, cultural, faith, and religious communities. To assist us in promoting an inclusive community and help enhance the understanding among groups, we are presenting this interfaith/cultural calendar of observances to help increase awareness of and respect for religious obligations, and ethnic & cultural festivities that may affect members of our community. In addition, we added our industry’s monthly themes for 2023 for acknowledgment and awareness.

This calendar provides a broad outline of significant days within major faith traditions, as well as ethnic and cultural celebrations. We encourage you to use this calendar and add to it as you wish. We hope this helps you become more aware, recognize our colleagues’ days of observances/holidays, and avoid the unintentional exclusion of those whose faith/religious traditions are not currently observed nationally.
