Busiest Day of the Year for USPS

Tuesday is expected to be the busiest day of the year for the U.S. Postal Service.

USPS officials are anticipating 658 million pieces of mail to be sent out, which is more than a 100 million more than an average day.

Thursday is the last recommended day to send mail expected to arrive before Christmas Eve.

After that, USPS recommends the two-day priority mail service or overnight express mail.
