Traditional Moladot for Hebrew Year 5785

Rosh Hashanah on the day of the molad.
Perfect Non-Leap Year (Cheshvan and Kislev both 30 days) in year 9 of 19 — Times Square, Manhattan, USA: 40.7566°N, 73.9862°W, elevation 35m, time zone -05:00

Molad moments are counted as elapsed time from zero at mean sunset, not mean midnight. Don’t convert this to civil time, any time zone adjustments are pointless,
and it never makes sense to add an hour to the announced molad time for Daylight Saving (see <http://www.hakirah.org/Vol 6 Loewinger.pdf>).
Last Old Crescent = calculated last visibility of old lunar crescent before sunrise if local conditions permit, with direction measured clockwise from true north (east = 90°).
First New Crescent = calculated first visibility of new lunar crescent after sunset if local conditions permit, with direction measured clockwise from true north (west = 270°).

In the era of the Maccabees, the traditional molad interval (29 days 12 hours 793 parts = 29 days 12 hours 44+1/18 minutes = 29+13753/25920 days
= 29.530594135802469... days) equaled the mean lunar cycle duration (synodic month), and the traditional molad corresponded to the mean new moon
(lunar conjunction) at midway between the Nile River and the end of the Euphrates River (4° east of Jerusalem = Jerusalem local mean time +16m).
Tidal transfer of angular momentum from Earth to Moon causes the mean synodic month to get progressively shorter (in terms of mean solar days),
so since the Hasmonean dynasty the accumulating molad interval excess causes its reference meridian to drift eastward at an accelerating rate.
As of Tishrei 5785 the mean synodic month ≈ 29.5305875921 mean solar days or about 0.57 seconds shorter than the traditional molad interval,
and the traditional molad = mean lunar conjunction at 30° 36' east of Jerusalem = Jerusalem local mean time +2h 2m 24s.
