1. This conversation is happening digitally, using devices that count time from the unix epoch

2. When was the last time you used a clock set by synchronizing it with a sundial or something old fashioned instead of having all your clocks and calendars set to what the electronic infrastructure of our time tells you?

3. I don't mean to be cynical - it's not like all the old fashioned people are gone. There are still monks all over the world who have tracked calendars by hand for centuries, without electronics. But if we're to trust they've counted correctly from a legendary birthday, then we should trust they've also counted correctly for the older calendar used widely before and after that, which started from the 312 "BC" conquest of Babylon by Seleucus I Nicator, which we still have documentation of from the time unlike the birth of the legend Christ. So, if you had asked me personally this question in a handwritten letter, I'd have been forced to pick between year 054, supported by the electronics I trust counting from the UNIX epoch; or the year 2335, I think is the one we're up to in the handwritten record, unless I'm off by 1 because I usually use the UNIX calendar and I can't remember if the other one has new years in January or whether it started from year 0 or year 1
