National Cheddar Day is observed worldwide every February 13 to celebrate cheddar cheese, one of the most popular cheeses globally. This holiday was established in 2019 by the Tillamook Country Creamery Association to honor its 110th birthday and the beloved cheese. Cheddar, which originated in the English village of Cheddar in Somerset, is known for its hard texture and sharp flavor. In the United States, cheddar is the most popular cheese, with significant production centered in Wisconsin and other states like California and New York. Celebrations often include cooking dishes featuring cheddar, such as grilled cheese sandwiches and mac and cheese, as well as hosting events like cooking workshops and cheese giveaways. Participants are encouraged to share their experiences on social media using the hashtags #NationalCheddarDay and #CheddarDay.
