First, time itself must be reset, so, as we understand things, whatever happens in this season is not going to complete key parts of Bible prophecy. Have you studied the collection titled, When Cometh That Thief in the Night?
Second, the New Moon is expected to appear in Jerusalem on Thursday, September 21. The 23rd of the month is too late, it just doesn't fit the Lord's calendar requirement.
Lastly, about Revelation 12:1, there's some things I understand about that passage, and some I don't.
1 A great and wondrous sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head. 2 She was pregnant and cried out in pain as she was about to give birth. ~ Revelation 12:1-2
I understand enough to say with confidence that what was learned from the fulfillment in 2 BC was that, without question, Jupiter is the 12 star crown, in a celestial sign fulfillment. The sign is not that the crown is in the woman's belly, or her legs, or chest. The crown of 12 stars, the planet Jupiter, appeared on her head. HER HEAD. That's not happening in this season, while Virgo is clothed with the sun and has the moon under her feet. See When Jesus was Born - The Celestial Signs.
