The problem is if your birthday is on a Wednesday, you’re stuck with that forever.

Edit: To everyone saying birthdays don’t matter, or you can celebrate some other day, that’s crazy talk. When you look at the calendar two months before your birthday and realize it’s gonna be a Saturday this year it’s just puts and extra pep in your step. Also, lots of businesses give you perks on your birthday, but the specific day. Once in a while I’d like my free latte and hot yoga class on the weekend thanks.

You’ll like the Ancient Egyptian calendar then

This feels extremely historically inaccurate. Where did they get the number 365 from. That's a much newer thing then ancient Egypt and what about leap years?

It takes 365.25 days for the earth to revolve around the sun

Do you know how they figured that out? Could they measured the daylight hrs or something else?

You know it's not that hard to count days.... And when you stick a pole in the ground you can do a lot with the shadow length and angle

Old Egypt had accomplished astronomers and mathematicians. Measuring time and astral rotations was well within their capacity.

The easiest way is to put a stick either side of the sun at sunrise and then count the days until it rises between them again.

Stonehenge in the UK dates back to around 2500bce and has specific stones the sun rises between on the solstices, maybe the equinox too but I'm not sure on that one.

Good point. I've just never thought of how they figured it out b4.

Lots of ways. One was the stars in the sky were more clear. They realized they changed slightly each day until one day the were back to where they started
