Celebrated on 10/15/2026
National Grouch Day, celebrated on October 15, was created by the children's television show *Sesame Street* in 1976. It honors Oscar the Grouch, the beloved green grouch who lives in a trash can. The day encourages people to embrace their inner grouch and express their grievances in a fun, lighthearted way.
National Grouch Day was first introduced on October 15, 1976, by the Children's Television Workshop (now Sesame Workshop) as a way to celebrate the character Oscar the Grouch from Sesame Street. The holiday was created to give fans a day to appreciate Oscar's unique perspective and to humorously acknowledge the grouchiness that everyone feels sometimes. The date was chosen to coincide with the start of the show's seventh season.
Over the years, National Grouch Day has grown beyond its Sesame Street origins. While it remains closely associated with Oscar the Grouch, the day is now observed by fans of the show and others who enjoy a playful excuse to be grumpy. Celebrations often include watching classic Sesame Street episodes, sharing grouchy quotes, and participating in social media posts using hashtags like #NationalGrouchDay. Some schools and libraries use the day to teach children about emotions and the importance of expressing feelings in a healthy way.
