Something I thought of today and I want to put it "on the table". Perhaps this will be a catalyst for some insight as to when the rapture event may take place.
When I was doing counts prior, I did not allow for an Adar II to be added at the end of a given year so that the feasts would stay in alignment with the agricultural cycles. I seems to me that during a seven year period of time that at least one Adar II would be added.
This would essentially bump an anticipated rapture event forward at least one set of 30 or so days in that the added Adar II would be included within the 2520 days.
