>> Our calendar purportedly begins with the birth of Christ in 0 A.D., right?
This is crazy. Of course there’s 0 AD. There’s also -1 AD, and there’s also 3010 AD.
A decade is a period of 10 years. From the zero time AD, the 10 year interval completes 10 years thereafter.
All I want to know is how many days elapsed between zero time AD and what’s considered to be 1 AD. If zero, then the decade intervals are 1, 11, 21, 31... But if 1 year elapsed between time zero AD and 1 AD, then the decade intervals are 0, 10, 20, 30...
Not even a nano second.
There was a “week of Zero” b/w December 24, -1 BC and Jan. 1, 1 AD.....
