September: Sun between Leo and Virgo, October: Virgo clothed with the sun ... (Revelation 12:1)
Jewish Calendar
The Jewish calendar was based on observation but after Rome destroyed the temple in 70 AD, switched to a 19-year calculated cycle (
Genesis 1:14). A leap year occurs 7 times in 19 years so a
leap month of 30 days is added every 2 or 3 years. When comparing the Sun to dates of various years using
Stellarium (400-2021 AD), the sun drifts backward from constellations about one day every seventy years. This is caused by an
axial precession or wobble of the earth. The 19-year cycle does not adjust for the drift so in 2021 (year before a leap year) months are thirty days early. Then 2022 adds leap month
Adar I which corrects the problem. In
Nisan, when the moon is in Libra, Scorpio and Ophiuchus during redemption, the calendar is aligned correctly.
Jesus Christ was born ~7-1 BC and died ~27-33 AD, then ~2027-2033 could be the Second Coming. So the years ~2019-2026 is a possible seven year rapture window as God prepares the world for the seven years of Tribulation, within the margin of calendar errors. Since we are at the end of the
Church Age, work but also watch for Jesus on the Feast of Trumpets.
