The Biblical Calendar

The main purpose of the Biblical calendar is to set the dates of the Festivals. The ancient Biblical calendar was a lunar calendar. During the time of Yeshua, the regulation of the calendar was the exclusive right of the Biblical court known as the Sanhedrin. Each new month called Rosh Chodesh (head of the month) in Hebrew was determined by a visual sighting of two witnesses who would testify that they saw the new moon to the Sanhedrin. From the testimony of the two witnesses, the Sanhedrin would declare that the new moon had begun. Each Biblical Festival could not be determined before the arrival of the month in which it was to be held.
