If you mailed Christmas cards or packages Monday, you were not alone. It's the busiest mailing day of the year.
The U.S Postal Service says about 830 million pieces of mail were sent Monday, a 40% increase over the average daily load.
Roughly 583 million pieces are mailed on a typical day.
"That means long hours and stuff, and being extra prepared for our customers and making sure they have a pleasant visit at the post office because there is so much traffic," said Meridian postmaster George Craig.
If you're planning to mail something, and want to get it there before Christmas, here are the guidelines. If you're sending by parcel post, it needs to be mailed by Wednesday. If you're sending it first-class or priority, you should mail no later than Dec. 21. For express mail, send it by Dec. 23.
