Matthew Nelson48 said:We could always just switch to the Milankovitch calendar since it's way more precise than the Gregorian one anyway.
Sure, you could, but from what I gather, that calendar is only marginally more accurate than the Gregorian system. We're talking about a difference of just one day every 2,800 years.
It’s actually pretty interesting that certain American churches have accepted his calculations without actually putting them into practice. It’s a bit of a missed opportunity; if they had, almost every Christian in the world today—aside from a few niche sects with their own specific schedules—would be celebrating the exact same holidays on the exact same day.
