It might not be a bank holiday in England, but St George's Day will be celebrated up and down the country today.
Just days after the long, hot Easter weekend, Brits have another reason to get down the pub. The patron Saint of England St George is honoured with a feast, making today a day of national celebration.
Today is also the first birthday of Prince Louis, who was born on St George's Day last year.
Here's everything you need to know about St George, and why he is celebrated as England's patron saint:
When is St George's Day?
St George's Day is celebrated every year on 23 April, which is believed to be the day that St George died.
It used to be a national holiday and major celebration in England, but the tradition died out sometime in the 18th century.
While St George's Day is still celebrated in England, it's not a public holiday anymore.
Who was St George?
St George is said to have been a solider in the Roman army at the time of the emperor Diocletian.
Very little is known about his life, but it's thought that he was executed in 303 AD for refusing to renounce his Christian faith.
Stories say that he had refused to comply with the Roman Emperor's orders that soldiers make sacrifices to pagan gods. He spent seven years being tortured in the worst ways imaginable, but he still refused to give up his religion.
Some legends even suggest that St George died three times during his tortuous ordeal and was brought back to life each time.
He was eventually beheaded in 303 AD.
He was canonized as a Saint by Pope Gelasius 1 almost 200 years later, in 494 AD.

Why is he the patron Saint of England?
St George never actually set foot on English shores. It's believed that he was born in Palestine, near the modern day Tel Aviv, and spent most of his life in what is now Turkey.
He was chosen as England's patron Saint in 1350, by King Edward III.
St George was admired for his bravery in the face of terrible suffering, and he was popular among European Knights and military men.
Some have even suggested that not being English actually gave George an advantage over other saints, as it meant that he wasn't associated with any particular region of the country. There would be no regional rivalry, and so everyone in England could unite behind St George.
St George is also the patron Saint of Catalonia, Georgia, Lithuania, Palestine, Portugal, Germany, Greece, Moscow, Istanbul, and Genoa.
In Catalonia, Spain, St George's Day is celebrated like Valentine's Day. It's traditional for men to buy their partner a rose, and women to buy their partner a book.
Did St George actually slay a dragon?
The story of St George slaying a dragon is thought to be at least 1,000 years old, so there's no knowing how it originated.
The legend goes that a town in Libya was being terrorised by a ferocious dragon. The only way that people could stop it from laying waste to their homes was by giving their children as a sacrifice to be consumed.
When the time came for the king's daughter to be fed to the dragon, George arrived and offered to help.
He told the king that - on the condition that everyone in the town was baptised - he would slay the dragon.
The king agreed to George's terms, and so George killed the dragon and saved the king's daughter.
Obviously there's no such thing as dragons, but the story embodies the popular "good triumphs over evil" moral.
Happy St George's Day!
