Saint David's Day is the feast day of Saint David, the patron saint of Wales, and falls on 1 March each year, chosen in remembrance of the death of the Saint. Tradition holds that he died on that day in 569. The date was declared a national day of celebration within Wales in the 18th century. Every year parades are held to commemorate Saint David. The largest of these is held in Cardiff and is formally attended by either the British Monarch or the Prince of Wales.
