Is the post office open on Martin Luther King Jr. Day?

MLK Day (the third Monday in January) is a federal holiday, and USPS observes every one of them. Routes don't run, post offices are closed, and Tuesday's carrier brings two days of mail at once.

It's a common mix-up because so much of the day looks ordinary — stores are open and FedEx trucks are still delivering. But the Postal Service takes the day off, and UPS observes MLK Day too, so most package tracking goes quiet along with the mail.
