(FOX19) - Monday is expected to be the busiest mailing day of the year, according to the United States Postal Service.
With a projected 420 million packages to deliver, it's crunch time for postal workers.
FOX19's Dan Wells got a sneak peek inside of the Cincinnati Distribution Center on Dalton Ave. a hub for the region and the largest distribution center in the area.
The facility has hundreds of employees working overnight, including temporary workers hired for the holiday season.
Meanwhile, USPS expects a 12 percent increase over last year, partly as a result of more people buying gifts online.
In total, the Postal Service expects to deliver nearly 15-billion letters, cards and packages from Thanksgiving to New Year's Eve.
Here are some important deadlines to know:
- Friday, Dec. 20: Deadline for sending first-class mail
- Saturday, Dec. 21: Deadline for priority mail
- Monday, Dec. 23: Deadline for sending priority mail express
- Wednesday, Dec. 18: Busiest delivery day for cards and letters
- Thursday, Dec. 19: Busiest delivery day for packages
- Tuesday, Dec. 24: Normal delivery day, but most post offices will close at noon.
