Kurzgesagt explains the Holocene or Human Era calendar, which adds 10,000 years to the current year to anchor dates to the start of human civilization. It argues this gives a more sensible frame for human history.

Linked whenever year numbering or the Holocene calendar comes up as the accessible introduction to the idea.

I've become an unironic proponent of HE, the Human Era. For CE dates, we just add 10000 (I'm writing this from 12025). But for BCE dates, they're subtracted and it makes things so much clearer when it comes to telling how long ago something was. E.g. the sundial was invented around 6000 HE, steel was developed around 9000 HE. Kurtzgesagt has a really great video about the subject: ▶ this video There's also a timeline in HE that covers many major historical events: link

I'm all for leaving a religious calendar and using the Holocene calendar. Just add 10,000 to your dates and you're set. link If you don't mind videos, here's a good explanation of it ▶ this video

As a sidenote, I love that you reference 1973 as 01973. I suggest considering labeling even as 11973, based on some reasonable humanist-based information.[0] [0] ▶ this video

Reminds me of the Holocene Calendar, which argues for setting the year 0 ten thousand years earlier to include all of major human history. So instead of writing 02022 AD it would become 12022 HE, for Human Era. It would mean to update these date libraries fast though... An episode of kurzgesagt about this topic: ▶ this video
