The other morning while I was brushing my teeth, I thought of the verse from the Book of Revelation (Rev. 8:1): "And when he had opened the seventh seal, there was silence in heaven about the space of half an hour." I thought, "Going with the '1,000 years equals one day' equation, how many years is a half hour?" Well, 1,000/48 = 20.83. So 20 years into the 21st century is...about half an hour.
Obviously, this is not a prediction or a prophecy of mine or anything. It's just a possible coincidence of some interest.
