Why didnt i die today?

if the world is actually going to end, it will be an immediate catastrophic event that may trigger other events. Theres no way one specific day can be singled out- some countries (like New Zealand) are a full day ahead of other countries around the US. So, you can ask, well, is it our May 20 or New Zealands May 20? If it were true the US would watch the world end over and over again as a date crosses into each time zone. Makes no sense.
