It's that time of year again. Time to don your favorite green apparel and hit your local pub for some green beer or a pint of Guinness. But why do we celebrate St. Patrick's Day? And what's with all the green?
The history of St. Patty's day as an official holiday dates back to to 1900's although it was celebrated as a national feast day in Ireland as early as the 10th century. St. Patrick, the most famous patron saint of Ireland, is regarded as the principal missionary in bringing Christianity to Ireland, where he used the leaves of the shamrock to teach the doctrine of the holy trinity.
Originally, the color associated with St. Patrick was blue, but to honor him, people would don a shamrock. Then, during a rebellion in 1798, Irish soldiers wore all green uniforms in hopes of drawing attention and support. This was known as 'wearing of the green'. Eventually green overtook blue, and shamrocks and their green color became the norm for those celebrating the day.
St. Patrick's has since spread to all corners of the world. It is widely popular in Canada, USA, Great Britain, Australia and New Zealand, and is even celebrated in Japan and South Korea.
