December is a busy month for post offices, as those holiday packages make their way from point A to point B.
However, if you plan on sending out any military packages, you may want to get that done sooner, rather than later.
Depending on where you want that package to go, it may even need to be at the post office by this Friday.
The deadline for parcel airlift military mail is December 4th, which is this Friday. That's also the deadline for some priority and first class mail.
Other deadlines are the 11th and the 18th, but it all depends on how and where it's being shipped.
All holiday shipping calendars can be found at www.usps.com.
