St. Patrick's Day, celebrated on March 17, honors Ireland's patron saint and national apostle, Saint Patrick—a fifth-century missionary.
A national holiday in Ireland, the festivity is marked by a range of cultural events, parades, and traditional music and dance enjoyed across the globe.
Interestingly, the first St. Patrick's Day parade wasn't held in Ireland but in the US. The earliest celebration was organized by Irish vicar Ricardo Artur in St. Augustine, Florida, in 1601.
