This means that that year, the 15th Abib Passover Feast30 AD on the Julian calendar gives a
- Wednesday March 22nd vernal equinox
- Wednesday March 22nd new moon
- and a Thursday April 6th full moon.
was on the full moon.
Did you also consider that the whole of Jerusalem witnessed Christ
descending the Mount of Olives and entering the city -
only to get to the Temple just before sunset ?
This was definitely not the weekly Sabbath !
As shown, it was actually "Palm Saturday" !
That year, the next Roman day of the week was Sunday:
after whipping the traders out first,
Christ did then teach in the Temple,
as was his custom on the weekly Sabbath !
up to the next vernal equinox, the Biblical weekly Sabbath
partially overlapped the Roman Julian Sunday.
The next Biblical year, starting again
at sunset on the vernal equinox,
the Biblical weekly Sabbath, would have overlapped
a different day of the Julian week !
As shown in this thread, the first Biblical day
of every year, is always the 4th day of the week -
a High Day Sabbath, not a Weekly Sabbath !
