Saint Patrick's Day
Saint Patrick’s day (aka Feast of Saint Patrick) is celebrated on March 17th every year, the official death date of the foremost patron saint of Ireland, Saint Patrick. In a well-known legend, Saint Patrick used a three-leaved shamrock to explain the concept of the Holy Trinity to Irish pagans. Green wasn’t actually the color associated with Saint Patrick, it was originally blue. The combination of emerald/green and the legend of the shamrock were the reasons that green became the widespread color to be worn on Saint Patrick’s day. This celebration and holiday extended all across the world with the Irish population along parades (which actually started in America due to the large influx of Irish immigrants during the potato famine) and the wearing of green even if you’re not really celebrating or honoring the saint.
