1st day of the month of Adar, and the second day of Rosh Chodesh Adar, 5770.
As we previously explained, whenever the preceding month (in this case, Shebat) has 30 days (the months in the Hebrew calendar could have 29 or 30 days) then Rosh Chodesh is celebrated for two days: the 30th day of the preceding month and the 1st day of the new month.
There is a third special thing about the month of Adar. During some years (leap years) we add an extra month to our calendar, a 13th month, a second Adar. Tomorrow B’H we will explain why we need to add a thirteenth month.
Chodesh Tov!
And now a question for you: What happens if for example, a boy is born during a year that has only one Adar, and his Bar Mitzva falls on a year that has two Adars. Does he celebrate his Bar Mirtzva, during the first or during the second Adar? Send your answer today: halakhaoftheday@gmail.com.
