- n. The birth-time or beginning of the new moon. The Jewish month is lunar and therefore begins with the molad. See roshhodesh.
Sorry, no etymologies found.
This is precise moment that has been announced every month in traditional Jewish synagogues for thousands of years, and that is why every traditional Jew has grown up with the words resonating in his ears, "And the molad this month is..."
The later Aramaic word for the first appearance of the new moon is molad, the exact moment when the new moon appears, but literally, the birth every month of the new moon.
Irv Bromberg has proposed a 353-year cycle of 4366 months, which would include 130 leap months, along with use of a progressively shorter molad interval, which would keep an amended fixed arithmetic Hebrew calendar from drifting for more than 7 millennia.
