My twin and I constantly argue about who is the elder. He claims that just because he was born first, he is older than I am. I refute his claim and point at our birth certificates, which clearly show that I am older. Our mother says it doesn't matter since we have the same birthday and tells us to stop bickering!
We're both telling the truth, but how can this be?
Similar to a recent puzzle,
You were born on a day when Daylight Savings Time ends, rolling the clock back one hour. If your twin is born just before the rollback time, 2am for the US, and you are born just after it, then your birth time is shortly after 1am and your twin's is shortly before 2am.
The recent puzzle: Missed Appointment,no doubt the inspiration for this one.
See comment below from OP for the actual inspiration!
There is another, I suspect less common, solution.
The mother was on a cruise in the Pacific, and crossed the international date line eastwards between the births, and to make it easy on us, she passes it in a place where she doesn't also change time zone (there are large stretches of the date line where this is the case). If she passes the dateline between the births, and midnight also passes between the births, then the second brother will be nearly a full day older than the first brother.
You could also do the boring variation and say she passes a time zone border westward between the births, but that only gives one brother half an hour on the other.
