What I’ve said is that the 2nd Coming is a much more likely fulfillment of Rosh Hashanah than the rapture of the Church. But keep in mind that between Matt. 24:36 and Matt 25:13 Jesus said no one will know the day or hour of the 2nd Coming no less than 4 times. Therefore any calculations that depend on knowing the date of the 2nd Coming cannot be trusted.
I have repeatedly refused to establish a specific date for the rapture because I don’t believe it’s a date specific event. I believe it’s number specific and no one knows either the predetermined number or the current number. What I do believe is that the rapture is very close and could happen any day
