Sourest Day is celebrated on October 25 in honor of all things sour, from your favorite sour candy to all the sourpusses in your life. In 1977, an Ann Arbor, Michigan, resident named Richard Ankli wanted to honor a friend with the last name Sauer on their birthday. The tart idea grew into an unofficial holiday for all the sour candy lovers and Grumpy Guses in our lives.

Sour is not just a means to add flavor and zest to our food. It is also a common state of mind for a majority of the population. Who doesn’t have a testy relative or cantankerous friend who continually sees the glass as half-empty? Go to those sullen saps and let them know this day is just for them and their sour disposition.

How to Celebrate Sourest Day

Get ready to make your mouth water with an entire day of all things sour, starting with a breakfast grapefruit with no added sugar or sour candies that make your whole face pucker. Have some friends over to experiment with sour foods and document their reactions for some great Tik Tok videos. For those with a sour disposition, enjoy your day by making that frown even frownier. #SourestDay
