Recurrence pattern: every year in March.

Sinkie Day is celebrated on the day after Thanksgiving, and is founded by the International Association of People Who Dine Over The Kitchen Sink. This day recognizes the practice of eating informally, often over the kitchen sink, to avoid the hassle of cleaning up after a large holiday meal. The concept of a “Sinkie” includes anyone who enjoys quick, casual eating habits, such as consuming food directly from the refrigerator or eating off a car dashboard. The celebration encourages participants to let go of formal dining traditions and enjoy food in a relaxed manner, emphasizing convenience and spontaneity. Typical customs include grabbing leftovers and eating them without the need for a table setting, making it a favored holiday for those who appreciate a more laid-back approach to meals.
