God is using the 360 day calender in the old testament, and clearly is using a 360 day calender with how he resolves events that have yet to occur in the book of Revelation.
I honestly don’t believe there’s any reason to assume he’s not using the same accounting of time in between these events,
Without going into any details, I can say, that if you do look at important events and intervals in that manner, it does appear to show interesting structures and patterns that at least have an appearance of being attended too, and that align with his Feast days far into the future,
Our present 365 day orbit has to be changed before the the 360 day prophecies are fulfilled, else how would we “watch?”
Presently, the Lord’s appointed times do not work at all. Judah has attempted to make their calendars to work, but to no avail, they have to be readjusted each year, in approximation.
To me that is a clear indication that we simply have to wait for that condition to be changed before we claim that his coming is immanent.
