Are post offices open on Thanksgiving 2011?
Thanksgiving 2011 falls on November 24
Just like banks, post offices in the United States also observe Thanksgiving and will not be open, and no mail will be delivered for the entire day.
Thanksgiving is just one of the holidays observed by the US Postal Service, with the next day off being Christmas Day.
Trying to send a package by a service such as UPS will not be an option either, as they also do not deliver on Thanksgiving, or Black Friday. So they are taking two days off.
So make sure you send your packages today if you need to!
