Holy Day Dates: These dates are 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.
After the difficult 2018 moon sightings all sightings through 2027 are firm, unless there is heavy cloud cover.
