2018 Religious Observances
The calendar below is a month-by-month listing of religious observances in 2018. The list includes the dates for some of the most important religious celebrations of the major religions. Some of these holy days include fasting or abstaining from specific food or drink for specified periods ranging from a month, to a day, to daylight hours (sunrise to sundown).
This list is by no means comprehensive. For additional holy day listings and descriptions, please consult the global Interfaith Calendar.
* Some holy days start at sundown of the evening before the listed start date and end at sundown or nightfall of the concluding date listed.
# Some of these dates are not fixed to a calendar, but are based on the actual sighting of the moon and therefore there may be some variance by a day.
