Holiday and Observances Calendar

This calendar lists holidays, traditional observances, and major days of religious significance. Use these dates to aid in developing class syllabi and class quarter planning. Although many of these days are not college holidays, faculty are asked to use this information at their discretion when responding to student requests for time off for religious purposes. Please take special note of those holidays that have been designated non-work days by the religions that celebrate them.

Note:

  • All Jewish and Islamic holidays begin at sundown on the evening before the first date shown.
  • Some of these dates are not fixed to a calendar but based on the actual sighting of the moon and therefore there may be some variance by a day.
