I am no scholar concerning Jewish feast days or leap years
so I can not give you a solid answer to your question from
your post.
But your
question about what day the abomination of desolation
might fall on did get me to focus on some
possible scenarios of that and other dates.
If I am correct (from my graph below) and
that the arrival of God's two witnesses initiates
the start of the 7 year tribulation period.......
then when might the two witnesses show up? What Jewish feast
day mandates that two witnesses witness the arrival of
the new moon?....... Rosh Hashanah
When is Rosh Hashanah celebrated? It varies but normally
in....... mid September.
So from my chart if God's two witnesses showed up in
mid-September as the start of the 7 year tribulation period
and (from my chart) the rapture happened 1335 days later,
where does that take us? Rapture in
late May or early June. Does that make sense
scripturally? Yes, The Song of Solomon and Isaiah 18 both
indicate that Jesus comes for his church in late spring.
Then from my chart .....assuming that the two
witnesses arrive on Rosh Hashanah......when would
the abomination of desolation happen? As per the chart, it
would happen around mid-February.
Does that make sense scripturally? In Matt.24:15 Jesus is
speaking to the Jews about "the abomination of desolation" and
instructs those Jews to immediately flee to the mountains if
they see the "abomination" being set up in the holy place.
Then Jesus gives them a hint when this may happen when He
says......."And pray that your flight
may not be in winter or on the Sabbath". Mid-February
is definitely winter and if I were a betting man I would wager
that Jesus was more than just giving them a hint as to the
timing of the abomination of desolation being "set up".
It appears to me that the "abomination of desolation" will
be set up in Jerusalem 41 months after the arrival of
God's two witnesses who arrive on Rosh Hashanah. I
believe this will happen in mid-February on a Saturday (the
Sabbath). Once the two witnesses show up on a specific
year the exact date of the "abomination of desolation"
can be determined.
