I think satan with a few thousand years of study time would know the bible better than anyone who is alive. However, I dont think he would have any advance notice about the rapture, just like the church will not. What he probably has been doing for many centuries is having someone always prepped to be the AC in case the rapture happens during that timeframe.
I agree but i do think he's able to recognise or see the season better than us due to his knowledge of scripture
