Why do we wear green on St. Patrick's Day?
Originally, the color associated with Saint Patrick was blue. Over the years it changed to green because St. Patrick is said to have used the shamrock to explain the Holy Trinity to the pagan Irish. Also, in the 1798 rebellion Irish soldiers wore full green uniforms on 17 March in hopes of catching public attention.
The phrase "the wearing of the green", means to wear a shamrock on one's clothing. So, are you "wearing the green" today?? I am.
