More packages will be mailed Monday than on any other day of the year.
Millions of people are expected to mail packages and cards between now and Christmas. The busiest day during that time is expected to be Monday, and the second busiest Saturday the 21st.
The Postal Service says to get your packages and cards to their destination by Christmas, they need to be in the mail by Monday if sent by standard first class mail. People who use priority mail should have them in the mail by Friday, the 20th.
