Shrove Tuesday - which is also known as Pancake Day - is celebrated every year before the start of Lent.
It is the time most of us feast on crepes and fluffy American pancakes smothered in sugar and lemon, maple syrup, chocolate, fruit and more.
But why do we eat pancakes on Shrove Tuesday? Here's everything you need to know about its origins and history.
When is it?
Shrove Tuesday is on Tuesday, February 28 but the date changes every year depending on when Easter falls. It is celebrated before Ash Wednesday - the fist day of Lent.
Why do we celebrate it?
Pancake Day is originally a Christian holiday and marks the day before Lent begins. The sweet treats were traditionally eaten to use up rich food like eggs, milk and sugar before the 40-day period leading up to Easter Sunday began.
The ingredients used to make pancakes are said to symbolise for points of significance during this time of year. Eggs are said to signify creation, flour - the staff of life, salt - wholesomeness and milk - purity.
Some suggest the days origins date back to a Pagan holiday which celebrated the arrival of spring.
What does Shrove Tuesday mean?
The day gets its name from the ritual of shriving which means an act of confessing sins and getting absolution.
When a person is given absolution by a priest they are forgiven in the eyes of God.
In Anglo-Saxon times a bell would be rung to call people to confession which came to be known as the Pancake Bell.
What else do we do except eat pancakes?
Aside from the joy of pancakes some parts of the UK hold pancake races for the local community.
The contestants have to run while trying to toss a pancake in a frying pan at the same time.
The races date back to the Middle Ages and were considered an important part of the festivities.
