Jesus was crucified on Passover. He was placed in the tomb just before sundown for the Feast of Unleavened Bread and raised from the dead on First Fruits. The Holy Spirit fell on Pentecost at ( 9 AM ,ie the 3rd hour) which was the time of the morning sacrifice at the Temple. The next feast is the Feast of Trumpets which is the only feast that no one knew the hour or day. It is the only feast which falls on the first day of the month. The first of the month began when 2 witnesses could see the first little sliver of the light of the moon after the new moon. The High Priest would declare that this was the first day of the 7th month.
The Feast of Trumpets is also the feast where last trump is blown. The day is also known as the day of judgment. The Rapture is also a judgment day. Only the true believers will be raptured and everybody else will be left behind.
It was God that set the pattern with the feasts. We do know that Jesus fulfilled the first 4 feast exactly and in detail. I do not believe that God will break the pattern which He has established.
We can discern the times and seasons and we know that the Feast of Trumpets is very near but do not know the day or hour.
I am not saying that the coming Feast of Trumpets will be the Rapture of the Bride of Christ. The rapture could take place a later time but on the Feast of Trumpets.
