OK, it was the year 2761 using the correct calendar established by G-d, instead of the pagan Roman calendar.

Thanks Jewbacca (great name by the way) When does the Jewish calendar start? Coming out of Egypt?

[Jewbacca]

“When does the Jewish calendar start?”

One year before the date of Creation (give or take; there is a missing 165 years, that is a subject of much dispute).

That said, ever since R’ Azariah dei Rossi, in Me’or Einayim, it has been accepted that the traditional Hebrew dating is not historically precise regarding the years before the Second Temple.
