National Grouch Day

National Grouch Day is an annual holiday celebrated on October 15th, in honor of the beloved Sesame Street character, Oscar the Grouch. This day is all about celebrating the grumpy lifestyle, and allowing people to express their grouchiness without judgement. It also serves as a reminder that it’s okay to take time to work through negative emotions.


National Grouch Day has been celebrated since at least 1976, though there is no specific origin for the holiday. It is about celebrating the life mission of a grumbler; to be as unhappy and grumpy as possible, while showing this state to others. Interestingly, there is actually scientific evidence that supports the idea that complaining can make life easier. While it’s not recommended to be a grumbler all the time, National Grouch Day gives people the chance to express their inner crybaby by complaining about everyday things.
