Where the World Gathers to Celebrate Every Day

SOUREST DAY – October 25

Sourest Day - October 25


Sourest Day is observed annually on October 25. Following on the heels of Sweetest Day, this is the Sourest Day of the Year.  

If life is giving you lemons or you feel like a grumpy guss, Sourest Day is for you.  Take your glass-half-full attitude and spread the joy -er- gloom.  Smiles be banished! Replace them all with pouts and terrible frowns.  


Bet you can stay sour ALL day! Use #SourestDay to post on social media.


Richard Ankli of Ann Arbor, Michigan created this counterpoint holiday in 1977 to honor of a friend with a Sauer last name and a birthday landing on October 25th.  

There are over 1,500 national days. Don’t miss a single one. Celebrate Every Day with National Day Calendar!
