Is there a specific time of day the world is supposed to end? Because looking at that clock it'd be 1 AM for me, but why 1 AM? It's not like when it's 1 AM here it's exactly midnight anywhere it the world and turning december 21st
I would guess midnight in a major Mayan capital. Chichen Itza in Mexico is on CST.
I visited Cancun once but didn't have a chance to go up to check out Chichen Itza.
