HOW DO THE RABBIS TEACH THAT WE ARE TO CELEBRATE THE NEW MOON?

• Individuals cannot unilaterally declare the new moon without the authority of the Sanhedrin

• The determination of the new moon establishes when the annual Festivals will be observed

• The weekly Sabbath is every seven days

• Hillel II in the 4th century established an exile calendar which will be used until the Messianic Era. The Messiah will establish a Biblical judicial court which will declare the new moon by visual sighting as in the days of old
