Using Jesus as a reference is unfortunate, yeah, but any other world calendars have to pick a nearly equally arbitrary way to contextualize the start and end year.
Take your pick: https://en.m.wikipedia.org/wiki/Template:Year_in_various_calendars
I personally use "2024 CE" for "common era", with BCE referring to "before common era". This allows us to communicate relatively clearly with other people who use the Gregorian calendar without explicitly endorsing the birth of Jesus as the important event defining the switch-over between CE and BCE... A bit of a cop out, but
Anyway have fun, there are lots of options
Edit: also the one you're referring to in your post is the Holocene Calendar
because the very first thing you say in this post basically amounts to "I think I have the authority to decide the basis on which we determine who deserves to vote"
like, yeah, most people can navigate to their secretary of state websites. And it's not really your responsibility to have to link the pages anyway.
But doing it for that reason aligns you philosophically with people who think that the illiterate, the elderly, the poor, the disabled, the critically ill, etc. somehow don't deserve to vote. It aligns you ideologically with other people who think they can decide who deserves to vote, with people who want to disenfranchise others-- in essence, it aligns you ideologically with many Republicans
