alt Hacker NewsI mean... That's kinda how it works? More than once I've halfway forgotten birthdays of friends who live in timezones to my east, and then sent them a message saying "Happy birthday! (It still is where I am, lol)".
I'm not necessarily defending the implementation, just pointing out another way in which time is irreducibly ambiguous and cursed.

A reminder associated with the birthday can and should be changed if I change time zones. But the birthday date didn’t change so it shouldn’t move to a different day.

You reminded me of some riddle I had once read that was about trying to figure out how someone could be born one year later but still be older than someone born in previous year. The answer to the riddle also relies on timezones. For sure, birthdates involve time zones.
The riddle explanation was something like: A baby is born in New York City at 12:15 AM on January 1. Thirty minutes later, another baby is born in Los Angeles, where the local time is 9:45 PM on December 31. Although the New York baby is actually older by 30 minutes, the calendar dates make it appear as though the Los Angeles baby was born first.
