Saint David's Day (Welsh: Dydd Gŵyl Dewi Sant) is the feast day of Saint David, the patron saint of Wales, and falls on 1 March each year. The date of 1 March was chosen in remembrance of the death of Saint David on that day in 589, and has been celebrated by followers since then. To celebrate this day, people wear a symbol of either a leek, or daffodil. The leek arises from an occasion when a troop of Welsh were able to distinguish each other from a troop of English enemy dressed in similar fashion by wearing leeks. An alternative emblem developed in recent years is the daffodil
In 2003 in the United States, St. David's Day was recognised officially as the national day of the Welsh, and on 1 March the Empire State Building was floodlit in the national colours, red, green and white.
A petition in 2007 to make St. David's Day a bank holiday was rejected by office of the then British Prime Minister, Tony Blair.
