St. Patrick’s Day is a fun holiday when green is seen at every turn. Beer, rainbows, and leprechauns are also a part of the holiday. Even though St. Patrick’s Day is a time to celebrate the noted St. Patrick, he wasn’t from Ireland as many people would assume. He was from Britain. Although people wear green for the holiday, the original color to celebrate the day was blue. The shamrock was originally used in schools to teach children about the Holy Trinity. New York celebrated the holiday with the first parade in the United States in the 1760s. Today, most states take part in holding St. Patrick’s Day parades with colorful floats, Irish music and plenty of green seen on the streets and sidewalks. Many famous landmarks across the world light up in shades of green either the night before St. Patrick’s Day or the day of the holiday. The Sydney Opera House is one of the landmarks that transforms the exterior of the building to a brilliant shade of green as well as the Chicago River as several containers of dye are poured into the water. Over 5.5 million glasses of beer are consumed each year on St. Patrick’s Day, one of the biggest money-making days of the year for beer companies aside from New Year’s.
