Saint Patrick's Day (Irish: Lá Fhéile Pádraig) is a religious holiday celebrated internationally on 17 March. It is named after Saint Patrick (c.

Wearing of the green
Originally, the colour associated with Saint Patrick was blue. Over the years the colour green and its association with Saint Patrick's day grew. Green ribbons and shamrocks were worn in celebration of St Patrick's Day as early as the 17th century. He is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish, and the wearing and display of shamrocks and shamrock-inspired designs have become a ubiquitous feature of the day. In the 1798 rebellion, in hopes of making a political statement, Irish soldiers wore full green uniforms on 17 March in hopes of catching public attention. The phrase "the wearing of the green", meaning to wear a shamrock on one's clothing, derives from a song of the same name.
