Reply To: interesting calendar phenomenon

@ubiquitin u answered the question yourself. Many times Rosh Chodesh happens a day or two after the molad. And, as u mentioned that Rosh Hashana isn’t “arbitrary,” “Why would it be pushed off for no reason” “It can be pushed off…..Lo Adu Rosh.” There we go. so it’s not arbitrary, but there are dechuyos–even something not because of R”H itself but because of the consequences of having R”H being on certain days….so why can’t it be pushed off for the simple reason of maintaining a 29 day month?
