Time zone question

    If you are born in central time zone and you travel back to mountain time zone, do you celebrate your birthday according to central time or mountain time?

    Up to you. That's a matter of personal preference, not physics.

    How old you are can be calculated from UTC.

    If and when you celebrate your birthday is entirely up to you.

    I always celebrate on weekend after my birthday (celebrating in advance can bring bad luck :p )
