Happy Saint Patrick’s Day…Is It St. Patty’s Day Or St. Paddy’s Day?
Happy St. Patrick’s Day! Whether you’re drinking green beer, eating corned beef & cabbage or counting shamrock leaves, you might end up debating a popular St. Patrick’s Day question: Is it St. Patty’s Day or St. Paddy’s Day?
It’s easy to think that Patrick ought to be shortened as “Patty”. The name contains a T rather than a D, after all.(It's what I have always thought, until now) However, “Paddy” comes from the Irish name Padraig.
Saint Patrick's Day, or the Feast of Saint Patrick (Irish: Lá Fhéile Pádraig, "the Day of the Festival of Patrick"), is a cultural and religious celebration held on 17 March, the traditional death date of Saint Patrick (c. AD 385–461), the foremost patron saint of Ireland.
So, that's the the reason St. Paddy’s Day is spelled with a D instead of a T.
Cheers to knowing the correct spelling of St. Paddy’s Day!
