The first of March is Saint David's Day. Saint David is the patron saint of Wales. Legend has it that he was a Welsh preacher and religous official, who died on 1st March 589.
This day is widely celebrated in Wales with different events and public parades. Many events include singing and poetry reading. It is also quite common to wear a daffodil or leek on your jacket, two very Welsh symbols.
Many people eat cawl on this day - a kind of soup usually made with lamb and leek.
