People make St. Patrick's Day so popular

It's often suggested that everyone is Irish on March 17, which marks the celebration of St. Patrick, who is the primary patron saint of Ireland. The boisterous parades, jovial atmosphere and welcoming attitudes of pubs and partiers has undoubtedly contributed to the popularity of St. Patrick's Day. That popularity also benefits from Irish emigration. According to University College Cork, approximately 10 million people have emigrated from Ireland since 1800. Irish emigrants have relocated to countries across the globe, which perhaps explains why St. Patrick's Day is now celebrated in more than 200 countries worldwide. Though St. Patrick's Day is a religious holiday for many practicing Catholics, the day also is a largely secular celebration of Irish culture, which has remained popular thanks to the millions of people who have brought their heritage and customs with them even as they sailed away from the Emerald Isle, often in large numbers.
