YOUR GUESS WORK IS AS GOOD AS ANY BUT I CAN ONLY GO WITH
Mark 13:32
But of that day and that hour no one knows, no, not even the angels who are in the heaven, neither the Son, but only the Father.
MATHEW 36-41
36 “But about that day or hour no one knows, not even the angels in heaven, nor the Son,[f] but only the Father. 37 As it was in the days of Noah, so it will be at the coming of the Son of Man. 38 For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39 and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. 40 Two men will be in the field; one will be taken and the other left. 41 Two women will be grinding with a hand mill; one will be taken and the other left.

“That day” is the feast of Trumpets, that is the only feast day that occurs precisely at the beginning of the 7th biblical month, with the appearance of the new moon usually slightly after sunset, Thus, “only the Father” can know when it is going to happen. All of the other appointed times are in the mid month, and thus are knowable in advance.
