May 9th recognizes a fun and unique holiday, National Lost Sock Memorial Day. It is time to say “good-bye” to all of the single socks, the ones where their mates have been lost to the unknown. Where do all the missing socks go? Is there a washing machine heaven? This is a question people have been trying to solve for many centuries.  An answer may never be found to this problem, and life will go on.  How sad to have lost such a close-knit friend!

Of course, since before the dawn of Tupperware, inventors have attempted the prevention of such separation anxiety. Alas, if they had succeeded, mismatched socks wouldn’t be popular today. And, we there wouldn’t be pausing to remember them every May 9th.

HOW TO OBSERVE #LostSockMemorialDay

National Lost Sock Memorial Day reminds you that it’s time to move on. Let go of those lost socks. Clean out all of your left behind socks. Some ways to celebrate this unusual holiday include:

  • making sock puppets
  • turn them into dust rags
  • chose to never wear matched socks again
  • turn them into chew toys for pets 
  • make wrist warmers
  • make sock monkeys
  • fill them with beans and use them for your corn hole game
  • fill with rice and make a door stop
  • open up both ends of a long sock and make a plastic bag holder

What are some creative ways to use old socks? Share your ideas and say your final goodbyes to your lost socks using #LostSockMemorialDay.


National Day Calendar continues researching the origins of this fun holiday.
