The Father’s prophets have clearly stated that it is Tishri 1, and they are not “Hebrew Festivals,” but YHVH’s Appointed Times.
Literally all of his events occur on his appointed times, from the beginning to the end.
I think it more proper to state that his plan unfolds in the pattern denoted or “typed” by his established historic festivals...not necessarily by the calculated timings as men understand time! That the plan is unfolding like a flower blooming that undergirds all history is without doubt! How we time it is not how God times it, indeed God dwells outside of time.
For example, God said to Jacob that Israel would be 400 years in Egypt before he would bring them out. It was actually 480 years as Moses was 80 years old when he led the nation out. Now one could argue that the 400 years ended when Moses was born...but it still took 2 40 year generations before God had Moses ready to lead! Was God inaccurate in his statement to Jacob? No! At 400 years, Moses was born. Satan certainly was aware that God was ready to move as Pharoah had been provoked to kill the new born Hebrew male children...but like Satan has ultimately always done at important key junctures of spiritual history...”whiff, swing, and a miss!” God has always reserved for himself periods of indeterminate timing such as the suspension of the final activities of the 70th week for an unknown period(known only to God) as the Church age was in play...until he was ready to act!
