The question of, “Will mail be delivered on Presidents Day?” is answered with a big “No.” All post offices and federal offices of any kind will be closed for the holiday, which means that no businesses nor homes will get mail. This also counts out USPS packages. According to USPS, because it is a federal holiday, all federal offices are closed. However, all federal workers are still paid for the day.
As far as Fedex and UPS go, that’s a different story as it’s reported that:
Packages shipped through UPS and FedEx should still arrive if the delivery date falls on the holiday. Amazon.com says it processes and ships some orders on the holiday, but delivery may be delayed.
Holidays on which mail is not delivered are:
New Year’s Day
Martin Luther King Jr’s Birthday
Washington’s Birthday (President’s Day)
