1 March - Will the sun be shining on Wales as they celebrate St David's Day, the Patron Saint of Wales?

What is St David's Day?

St David was a Celtic monk in the sixth century, who then became the Archbishop of Wales and is the Patron Saint of Wales. The day is celebrated on 1 March as this marks the death of the saint in 589.

St David's Day is celebrated across Wales by the customary wearing of the country's national symbols - the daffodil or the leek. Young girls also often wear the national costume of Wales to school on St David's Day.
