Recurrence pattern: every year on November 29.

Throw Out Your Leftovers Day is observed annually on November 29 in the United States, encouraging individuals to dispose of food leftovers that may be spoiled or unsafe for consumption. The day serves as a reminder to clean out refrigerators, as hoarding old food can lead to health risks due to decreased nutritional value and potential toxicity over time. Many people accumulate leftovers due to forgetfulness or poor cooking habits, often resulting from overestimating food needs during gatherings. While the taste of leftovers may remain relatively intact, their nutritional benefits diminish, making it advisable to avoid consuming them for extended periods. This observance promotes not only cleanliness in the kitchen but also awareness of food safety and health.
