In the UK , Shrove Tuesday is also known as Pancake Day (or Pancake Tuesday to some people) because it is the one day of the year when almost everyone eats a pancake. Pancake Day (also known as Shrove Tuesday) is the last day before the period which Christians call Lent.
It is traditional on this day to eat pancakes. Lent is a time of abstinence, of giving things up. So Shrove Tuesday is the last chance to indulge yourself, and to use up the foods that aren't allowed in Lent. Pancakes are eaten on this day because they contain fat, butter and eggs which were forbidden during Lent.
