Then and now
Agree with MJR. Wonderful to get this summary of the ways we have kept track of time. Calendars or not I struggle to keep track of my time on any given day. I guess we can thank Christianity for the help in keeping or struggling to do so.
What a perfectly encapsulated brief history of time this was! I know many of these time quirks, but not all.
One interesting note: March 25 is the Feast of the Annunciation: when the Word became flesh i.e., 9 months before Jesus's birth. The fact it is generally near Easter is merely coincidental, as Easter more signifies the Passion and resurrection of Christ.
Interesting idea that just a couple of centuries ago, the English speaking world based their calendar on Christ's conception. We seem quite far from that idea now...
