@DoubleAA judaism.stackexchange.com/questions/29788/… do you know why the Rambam (and those who preceded him) continued to count years this way?

@robev I have no reason to think he generally counted years that way. Off the bat, it seems much more likely he was being very clear about the year in that halacha for greater comprehensibility across places and times. Check his letters, intros/signoffs, etc. -- see if he dated them and what date system he used there. That'd more likely be the way he generally counted years.

@robev Do you know why contemporary ashkenzim stopped? Yemenites dated their kethubboth and gittin exclusively לשטרי until magic carpet IINM

^^^ I have wished we had this feature more than once.

@SmokeDetector False positive. Not offensive, though it is not well-formatted.
