Saint Patrick's Day is celebrated on March 17th in honor of Saint Patrick, the patron saint of Ireland. It is celebrated with parades, feasts, and religious traditions. Saint Patrick was born in Scotland in 385 AD and was kidnapped to Ireland as a slave at age 16, where he eventually escaped. After becoming a priest, he returned to Ireland and used the shamrock to explain the Holy Trinity, helping to convert the Irish to Christianity. Green is the color associated with Saint Patrick's Day to represent the shamrock. Traditional Irish foods eaten include corned beef and cabbage. The Chicago River is dyed green for the celebration.
