its complicated, but it make even more sense than the secular calendar, because it stay perfectly aligned with the seasons.

Tishrey is the 1st month in the jew calendar FYI
oh and we dont count the days by numbers (1st , 2nd , 3rd etc…)
it goes like A of Tammuz , B of Tammuz .
up until J of Tammuz , then we start counting J-A of Tammuz , J-B of Tammuz and so on…. (there is a reason for this)
its a bit complex therefore we dont use it at all . only the religious people use this.

OK, thanks for the information.
