To answer the question of how I'll spend my last hours, I first need to know: May 21st in what time zone? It seems unfair to make any worthy believers in New Zealand wait an extra 18 hours or so before it's officially Saturday in the USA.
But at the same time, Rapture at the stroke of midnight in New Zealand means the event actually happens domestically on May 20th (and we know it MUST be the 21st because of the indisputable Biblical evidence and life is precious and God and the Bible). Maybe we'll have to wait until it's May 21st everywhere, in order to make sure any deserving Hawaiians get to go. Sorry for making you wait all day, Kiwis!
Or maybe the Rapture happens one zone at a time, a discrete uptake of believers in an instant, followed by almost 60 minutes of waiting before the next zone's clocks strike 12 and the calendar flips.
