We've long made feeble jokes about people born on leap day having a birthday only every 4 years. Leap months just occurred to me.
The Hebrew calendar adds a month 7 years out of 19.
In the Chinese calendar any month can be 29 or 30 days, depending on when the next new moon occurs. So if you're born on the 30th your birthday will come irregularly.
But in the traditional scheme, all birthdays were counted on the New Year. (I glazed over on this, and still don't understand how their leap months fall.)
