So you are using man made metrics to apply to God's calendar.My apologies, I was not trying to offend you.
The explanation concerning the 'little season' of Revelation 20 was given at the top of this post.
My purpose for bringing up the 360 days in a year was to show that, from God's original creation to the Flood, those years were structured in cycles that were based on 7's (days, months, years).
We can also consider other well known natural cycles, the unit of measure being 1 year, the Shemitah cycle being 7 years and the Metonic Lunar cycle being 19 years. These are the natural metrics that God created to keep time on the earth.
I agree that the 2000/2000/2000/1000 year breakdown resembles the creation week. Sure, that's a nice 7000 year picture, but it's also a very modern/western perception. If we look at the timeline as laid out in scripture, using the metrics that God has prescribed, we find that His increments are not nicely rounded.
Consider looking at the events of scripture through the following:
1 - 7 - 19 - 53 - 133 - 371 - 1007 - 7049
You present the metrics as coming from God... but these are still human metrics.
I don't worry about being exact... that is God's territory.
