National Thank A Mail Carrier Day (also known as Thank a Mailman Day) on February 4th reminds us that someone makes sure the mail gets through 6 days a week 52 weeks a year. The day reminds us just how important mail carriers are to our daily lives. Take time out of your day to thank the mail carrier responsible for delivering your mail.  

The Pony Express riders earned a famous reputation in their short existence. Their motto was “Neither rain, or snow, nor death of night, can keep us from our duty.”  This motto is believed to be taken, in part, from a motto dating back to ancient times. The most popular variation of this motto is “Through rain or snow, or sleet or hail, we’ll carry the mail. We will not fail.”

Fun Facts:
  • In 1775, the Second Continental Congress established the Constitutional Post–the first organized mail service in America.
  • As the nation’s first Postmaster General, Benjamin Franklin established many of the conventions we are accustomed to today.
  • Postage stamps were invented in 1847.
