National Cheese Lovers Day is observed worldwide every January 20, celebrating the love of cheese among millions of enthusiasts. This unofficial food day has its roots in the United States and encourages cheese lovers to indulge in various cheese varieties. The history of cheese dates back over 8,000 years, with its first recorded mention found in Sumerian texts from the 22nd–21st century BC. Traditionally made from cow’s milk, cheese can also be produced from sheep, goat, or buffalo milk, with around 500 recognized varieties by the International Dairy Federation. Celebrations often include hosting cheese parties, trying new cheese selections, or enjoying dishes like cheese fondue or cheese pizza. The day is a tribute to the rich history and diversity of cheese, which has been a staple in many cultures, particularly in Europe, North Africa, and the Middle East.
