Much to the confusion of my parents (and everyone else I’ve spoken to about this), I decided last year to begin observing my birthday according to the Hebrew calendar. With the aid of the wonderful website HEBCAL.COM, I went back to the March 3 of 1989, converted it into the corresponding Hebrew date, and found that my birthday was actually on Adar 27.
Since 5768 will only be the second year in which I’ve done this, it my first year to observe my birthday in a shanah me’uberet (leap year). Since a shanah me’uberet contains two months called Adar (Adar I and Adar II), this causes a bit of confusion. I assumed that Adar I is the real Adar and that Adar II is the additional Adar. With this assumption in my mind, I calculated that my birthday would fall this year on March 4. This, as it turns out, is wrong.
Thank God for Faithhacker, one of the many excellent blogs of Jewcy.com. Tamar Fox, wrote on Faithhacker a great little article on the month of Adar. In the article, I learned that Adar I is actually the additional month and that Adar II is the real Adar. Yahrtzheits and birthdays that occurred in Adar in a normal year are apparently to be observed in Adar II of a shanah me’uberet.
And so my birthday is actually on April 3 this year!
