Festival Calendar

Holy Day Dates:  All Days begin at sunset on the previous calendar date.

This calendar is based on the Biblical system of observing the first light of the new moon at Jerusalem. 

Whenever possible these calculated dates should be confirmed by actual observation at Jerusalem.  We will announce New Moon sightings at this site.

For more information please see the Biblical Calendar posts.

All days begin at sunset the previous calendar day.

We are to use the day preceding the weekly Sabbaths and the annual High Holy Days to properly prepare, including cooking, because no work of any kind is to be done on any High Holy Day or weekly Sabbath; including traveling or cooking and the buying of food and drink.  That means NO paying bills, going out to restaurants and traveling on the Feast of the Eighth Day either.

There will be extensive posts for the Fall Festivals; and for the record, our Sabbath and Holy Day posts are written in advance and scheduled to be published automatically on the weekly Sabbaths and annual High Holy Days.   Of course it is proper to present Bible Studies on Sabbaths, I mean that the extensive writing and preparation for publication is done in advance.

Calculated first light of the New Moons

This is based on Israel Standard Time.  Adjustments must be made by adding one hour during periods of Israel Daylight Savings time.
