While St. Patrick may be more well known in America, today is Saint David's day (Welsh: Dydd Gŵyl Dewi), who is the Patron Saint of Wales.
The Feast Day falls on 1 March, the date of Saint David's death in 589 AD. The feast has been regularly celebrated since the canonisation of David in the 12th century (by Pope Callixtus II).
One of the famous stories is from when he was speaking to a large crowd and someone in the crowd shouted: "We won't be able to see or hear him." Then, the ground David stood on is said to have risen up so that he was standing on a hill, making it easier for everyone to see him.
A National St David's Day parade is held in the centre of Cardiff every year, with performances by dragons and theatre groups. Many children wear traditional Welsh clothing and take part in dances. Children in Wales take part in school concerts or eisteddfodau, with recitation and singing being the main activities.
The flag of Saint David often plays a central role in the celebrations and can be seen flying throughout Wales. Popular dishes traditionally eaten on Saint David's Day include cawl (soup), bara brith tea loaf, lamb and Welsh rarebit.
