The Earliest and Latest Moladot
The Earliest and Latest Moladot

by Remy Landau
=================================

The molad does not necessarily coincide with the first day of a Hebrew month. The molad can arrive as early, and no earlier, than the 28th day of a closing Hebrew month, and it can be as late as, but no later, than the close of the first day of a new Hebrew month.

The Earliest Molad Time

The molad can arrive no earlier than 28d;3h;340p in any given Hebrew month.

This earliest possible molad will first occur on the 28th day of Tevet 193,150H.

The Earliest Preceding Molad

The molad can precede the first day of a new month by a maximum of 2d;9h;453p.

This maximum separation between the molad and the new month will first occur on the 28th day of Kislev 193,150H.

It is interesting to note that both of these two phenomenas take place one immediately after the other in the same 355 day Hebrew year.

The moladot for that Hebrew year, and their corresponding Gregorian dates are shown below.

The Maximum Molad Time

The time of the molad cannot be any later than 23h;23m;8hl of the first day of any month.

This amazing feature of the Hebrew calendar is fully analyzed in the Additional Notes which deal with The Overpost Problem.

Assuming no changes to either the Hebrew or the Gregorian calendars, then this maximum time will first occur on the first day of Shevat 128,459H.

The moladot for that Hebrew year, and their corresponding Gregorian dates are shown below.
