The Hebrew calendar has 12 months plus a thirteen’s one that is added to the year every two or three years (see table below). This is to compensate for the fact the Hebrew calendar is a strictly lunar calendar. This means that, as there are approximately 12.4 lunar months in every solar year, a 12-month lunar calendar is about 11 days shorter than a solar year and a 13-month lunar is about 19 days longer than a solar year.
