Calendar of Religious Holidays at Colby

The list that follows is not exhaustive; it includes major festivals and holy days for many, though by no means all, religious traditions present in the Colby community. (If it does not include an important date in the religious calendar of your particular tradition, please let us know.)

Every effort has been made to insure that this information is accurate. Note that some holidays in some traditions are tied to the lunar calendar or to particular cultural patterns that vary by region or by sect, which make their location in the calendar somewhat more fluid.

Dates marked with a double asterisk (**) denote occasions on which the precept of a particular tradition, and the practice of nearly all its adherents, includes significant restrictions on academic activity.

A note on Islamic holidays

Regional customs or moon sightings may cause a variation of the date for Islamic holidays, which begin at sundown the day before the date specified for the holiday. The Islamic calendar is lunar and the days begin at sunset, so there may be one-day error depending on when the new moon is first seen.

Notations for Christian holidays
