Last Updated on: January 8th, 2024

Here are a few of the most interesting St Patrick’s Day facts and statistics I was able to dig up in my internet travels. As always, be sure to check back in the future as I will be updating this post as new and updated stats become available.

St. Patrick’s Day is an annual cultural and religious holiday celebrated on March 17th, honoring Saint Patrick, the patron saint of Ireland. It is a public holiday in Ireland, and also widely celebrated in many other parts of the world, particularly in the United States and Canada, where many people of Irish descent live.

The origin of St. Patrick’s Day dates back to the early 17th century when it was made an official Christian feast day by the Catholic Church in honor of Saint Patrick, who is believed to have died on March 17, 461 AD. Saint Patrick is known for bringing Christianity to Ireland, and his feast day has been celebrated by the Irish for over a thousand years.

The day was originally a solemn religious holiday in Ireland, but over time it has become a more secular celebration of Irish culture and heritage, with parades, parties, and other festivities. Many people wear green on St. Patrick’s Day as a symbol of Irish pride, and it has become a popular day for drinking and socializing, particularly in the United States.
