December 21, 2015 FORT WAYNE, Ind. (WANE) – It may be just four days until Christmas, but December 21st is also an important date for the United States Postal Service. It’s officially considered the busiest mailing day of the year.

With some 30 million packages going out worldwide Monday, postal service leaders said the sheer volume of packages is up 15 percent from this time last year. While it makes for a very busy December, post offices are working around the clock to make sure packages get from their stations to people’s front doors by Christmas Day.

“It happens every year, and we are seasoned,” Northwood Post Office manager Kim Early said.

For the last 37 years, employee Kevin Hirsch has helped customers through this very busy day.
