ct being the age of the moon of Tebet at the beginning of
the Gregorian year, it represents the day of Tebet which corresponds to
January 1; and thus the approximate date of Tisri 1, the commencement of
the Hebrew year, may be otherwise deduced by subtracting the epact from

Sept. 24 after an ordinary Hebrew year.
Oct. 24 after an embolismic Hebrew year.

[v.04 p.1001]

The result so obtained would in general be more accurate than the Jewish
calculation, from which it may differ a day, as fractions of a day do not
enter alike in these computations. Such difference may also in part be
accounted for by the fact that the assumed duration of the solar year is 6
min. 39-25/57 sec. in excess of the true astronomical value, which will
cause the dates of commencement of future Jewish years, so calculated, to
advance forward from the equinox a day in error in 216 years. The lunations
are estimated with much greater precision.
