Pancake Day, also known as Shrove Tuesday, is celebrated in the UK as the day before Ash Wednesday, marking the start of Lent in the Christian calendar. Traditionally, it was a day for using up rich ingredients like eggs, milk, and sugar, which were restricted during Lent. The day is now most commonly associated with eating pancakes, with many people cooking and enjoying them in various styles.

In addition to the food, Pancake Day is famous for the "Pancake Race" in some towns, where participants, often in costumes, run while flipping pancakes in a pan. The day is a fun and festive occasion before the more solemn period of Lent begins.
