TL;DR
- St. Patrick's Day, observed on March 17th, originated from the death of St. Patrick in 461 AD.
- Despite being the patron saint of Ireland, St. Patrick was born in Britannia, not Ireland.
- The celebration has evolved from a religious observance to a widespread cultural phenomenon.
- The color green, now synonymous with the holiday, was adopted in the 19th century, replacing blue which was previously associated with St. Patrick.
- The first St. Patrick's Day parade occurred in Boston in 1737, with Ireland adopting the tradition much later.
- The Leprechaun, a figure from Celtic folklore, is often associated with the holiday but has no direct link to St. Patrick himself.
- The modern, cheerful image of the Leprechaun is a relatively recent cultural construction, popularized in the 19th and 20th centuries.
