Not so. The question guarantees the day under discussion is Friday, not a named date. The only Friday of the year on which the Post Office is always closed is the day after Thanksgiving.

Therefore, it's whichever Pres was born in late November. Which I don't have a clue about because Presidential birthdays aren't of much interest.

The question doesn't say the birthday is on a Friday every year. That would be impossible, anyway. Nobody's b-day is weekday-dependent. I'm going with the 7/4 or 12/25 theory.

I disagree. Not trying to pick a fight just a semantics issue.
