Some factors that go into this equation:

Universal Time (UT) was 03:05:19, Sunday, 11/13/1758.
(That’s 3.10527777777778 in decimal hours.)
The Julian date was 2363473.44441898.
The sun’s ecliptic longitude was -46929.3133137296 degrees.
Its mean anomaly was -47210.6017682658 degrees.
The moon’s mean longitude was 318.351648 degrees.

These calculations incorporate the switch to the English New Style (N.S.)—i.e., Gregorian— calendar after Wednesday, 02 September 1752; the next day became Thursday, 14 September, skipping eleven days. (Please also note that, while fairly accurate, these calculations remain a bit buggy.)
