Sourest Day is a holiday that’s celebrated on October 25th—approximately nine days after Sweetest Day. Depending on whom you talk to, this holiday is either all about the best sour foods, such as sour candy, pickles, or sauerkraut, or it’s about cheering up the sour people in your life. Regardless of the actual purpose of this holiday, we think that everyone can get a kick out of celebrating it.

The History of Sourest Day

Okay, maybe we’re wrong about the purpose of this holiday, and as we researched this holiday, we discovered we were really wrong. This holiday isn’t about improving a person’s mood or enjoying sour foods. No, it was originally invented by Richard Ankli of Ann Arbor, Michigan, in 1977.

Why did he invent this holiday? He invented it because his friend’s last name was Sauer, and his birthday fell on October 25th. Since we don’t know Mr. Sauer, however, we’re just going to have to celebrate that day in our own way, and that’s by enjoying a bunch of sour foods.
