St George's Day is celebrated on April 23rd each year to commemorate the patron saint of England, St George. St George was a Christian martyr who was said to have been born in Cappadocia, an area in modern-day Turkey, in the late third century.

According to legend, St George saved a princess from a dragon and became a symbol of bravery and chivalry in medieval times. He is also known for his military service in the Roman army, and is considered the patron saint of soldiers and cavalry.

St George's Day has been celebrated in England since the 13th century, but it has lost some of its significance over time. It is not a public holiday in England, but it is observed by some people who wear a red rose, the national flower of England, or a St George's cross, a red cross on a white background that is associated with the saint.

Some communities hold parades or reenactments of the St George and the Dragon legend, while others celebrate with traditional English food and drink, such as roast beef and Yorkshire pudding, fish and chips, or a pint of ale.

Overall, St George's Day is an important day in the English calendar, and a reminder of the country's history and culture.
