Adar is the sixth month of the Hebrew calendar, typically falling between February and March in the Gregorian calendar. It is known for its joyful celebrations, particularly the festival of Purim, which occurs on the 14th day of Adar. This month is associated with themes of happiness and redemption, as it commemorates the events in the Book of Esther. In leap years, the Hebrew calendar includes an additional month called Adar II, which follows the regular Adar. This adjustment ensures that the lunar calendar aligns with the solar year. Adar is also a time for reflection and preparation for the upcoming month of Nisan, which marks the beginning of the spring festivals, including Passover.
