How long has st paddy's day been celebrated?

St. Patrick's Day has been celebrated for over a thousand years. The day was originally established as a feast day in the early 17th century, commemorating St. Patrick, the patron saint of Ireland, who died around 461 AD. The first recorded St. Patrick's Day parade took place in New York City in 1762, though celebrations and observances of the day have evolved significantly since then. Today, it is widely celebrated around the world, particularly in countries with Irish communities.
