Veadar is a month of the Jewish calendar intercalated at leap year. The ordinary year consists of 12 lunar months, making 354 days. To ensure that Passover, the 16th day of Nisan, shall occur at the full moon of the spring equinox, an adjustment is made by introducing a leap year of 384 days. This leap year comes seven times in each period of 19 years. In the leap year, an additional day is added to the monthAdar and the remaining 29 days form the month Veadar (double Adar), which is intercalated between Adar and Nisan, thus becoming the 7th month of the civil and the 1st of the ecclesiastic year.
