Given that twins/triplets etc. are generally not born simultaneously, there must be some twins with different birthdays

If one is born sometime before midnight and one after they have different birthdays.

If twins are born as daylight savings turn over, the twin born chronologically later can have their official time of birth before their older sibling

that's amazing. I'm torrenting this fact for the many parties I'm invited to (0).

Even millennias, though that chance has passed for a while.

I mean they'd be like what, 25 by now?

On at least two occasions, a woman gave birth to twins right at the end/start of the year, resulting in twins born in different years.

According to my googlefu. The longest amount of time between two twins being born is 87 days.

They could be a day apart in a leap year!

My husband and his brother were about 20 mins apart because it was a complicated breech birth. It was still on the same day, but it could have been what you are describing.

generally not born simultaneously

I'd say definitely not born simultaneously. Can you imagine?

This is conjoined twin erasure.

Oooh, good point. That'd be a photo finish out the garage door, for sure.

You could also have a delayed birth from one twin to the next. Delayed birth could happen for a load of reasons across various scenarios, but I'm guessing it could run in to several hours at times. It's probably on the rare-ish side, but very possible.

Sounds like a nightmare for insurance purposes, at least here in the states.

Given they tried to claim my identical twin was not my father's child but I was. (Twin cost a lot lot more. I was nicu for a week, they were nicu for a month)

The insurance company did not win that argument.

You claim one twin you claim both your dinguses.

The two most extreme time zones are 26 hours apart, so it's possible to have a twin born an hour after the other with a birthday two days earlier. With a little planning, that is.

OP is simply saying that the date of birth could be officially different. And birthdate is absolutely something for the records, for many obvious reasons.

Weird...

I clicked this thinking it was obvious...

And you don't think they record the minute for time of birth or a birth certificate?

Or care when midnight is crossed?

In America they do, but I'm interested in finding out what country doesn't care, so I can read up on how they do it out of curiosity.

Do they round by AM/PM?

Do they just record the week/month of birth?

I understand you may not be equipped to answer that, but if you can just tell me what fucking country on the planet doesn't care about minutes, hours, or even days on a birth certificate, I can find out for myself.

Edit:

Only think they might have meant was "delayed birth certificate" done for home births without a midwife and up to a year after birth.

On those, I think a time isn't needed, but they'd still obviously want a day.
