I would not be surprised if the counting one day will be reset to the invention of the computer. That would make us now 87 AC (anno computeri) assuming we count the invention from 1936.
well, the binary system is underrated as a general purpose tool. you could start by teaching kids that with five fingers you cannot only count to five but e.g. to 31...
I know this is very HN, but I thought it was about 6AD - there is some evidence of Herod running a census around then IIRR. (And no Joseph and Mary would not have had to travel for the census - that woukd defeat the point of a census ... It seems that is just a way to get Jesus born in Bethlehem as opposed to out of the way nowhere Nazareth).
