SOUREST DAY – October 25

Sourest Day | October 25
(Last Updated On: October 24, 2022)



Sourest Day follows on the heels of Sweetest Day. This sourest day of the year is observed annually on October 25th. 


If life is giving you lemons or you feel like a grumpy Gus, this 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.  

Wallow in your petulant mood. Take sulking to new lows. Frown like a clown catching the midnight train outta town. Develop a harrumph worth trademarking. Scowl so foul that people will catch a whiff of it before they even see you. When walking by a skein of yarn, it should leap onto your brow already knitted. That’s just how sour you need to be on this day.


Have a sour day, all day. Bet you can’t 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 a friend with a Sauer last name and a birthday landing on October 25th.  

Sour FAQ

Q. What are the five basic tastes?
A. Many experts agree that we taste five basic tastes on our tongues. Those five basic tastes are sweet, sour, salty, bitter, and umami, also known as savory. However, we also perceive two other tastes – astringent and pungent. While we may recognize the first five, astringent and pungent become more familiar to us when they are described.

  • Astringent -Tannins stored in the bark, skin, and other parts of some foods we eat make our tongues pucker or feel dry. For example, dry wine has more tannins from contact with the grape skins and when we drink it, the wine feels dry on our tongues even though it’s a liquid. Fresh grapes, apples, and teas will cause this sensation, too.
  • Pungent – This sensation creates heat on our tongues and lips. Jalapenos, peppermint, and mustard can all cause a pungent sensation.

Q. My friend is in a sour mood. How can I cheer her up?
A. Trying to cheer up a petulant friend can take some doing, depending on the circumstances. Besides showering her with a completely opposite attitude (sweet, that is), you can try these tips:

  • Tell a joke or funny story.
  • Try listening to them. Sometimes just being able to express how we feel makes us feel better.
  • Offer to watch a sitcom or funny movie with them.
  • Go for a walk with them. Exercise produces endorphins which are one of the happy hormones in our bodies.
