The Hebrew calendar is lunar-based. It uses the New Moon as a beginning for each month.

The sacred year usually begins with the first New Moon after the Spring (Vernal) Equinox. During Temple times, the High Priest would confirm the beginning of the year by determining that the barley was ripe (abib).

Rather than add a day every four years as with the Gregorian Calendar, the Hebrew Calendar adds an entire month every few years! As a result, the (official) Hebrew Calendar can be days off from the actual lunar cycle. You will note that the New Moon frequently does not correspond to the first day of the Hebrew month.
