Also, how would that work on things like birth certificates?

I feel like celebrating on February 28th when it's not a leap year makes the most sense. If someone was born on February 29, then their birthday is the day before March 1.

I feel like celebrating only on February 29th during a leap year makes the most sense. If someone was born on February 29, then that's their birthday and their rate of aging is slowed by %80.

[-] Rivalarrival@lemmy.today 19 points 9 months ago

Your 80% claim doesn't account for people who live through a year divisible by 100 but not 400.

Children born today could feasibly turn 18 in 2096, but won't celebrate their 19th birthday in 2100. They'll turn 19 in 2104.

If their birthday is really % 80 then they reset to a newborn after age 79.

Username checks out, gottem with the modulo.

Think about what your age is on Feb 28 and March 1 on non leap years.

[-] SeabassDan@lemmy.world 3 points 9 months ago

A year, basically, since you were born after the 28th but also before the 1st, so the next year before the first would already be a year again. Mar 1st would be a year and a day, technically.

If you want to argue for celebrating on the 28th, I would argue that you are actually 1 year older the day before your birthday. That is why you can buy alcohol the day before you turn 21. At least where I live.
