Saint Patrick's Day (Irish: Lá ’le Pádraig or Lá Fhéile Pádraig), colloquially St. Paddy's Day or Paddy's Day, is an annual feast day which celebrates Saint Patrick (circa 385–461 AD), one of the patron saints of Ireland, and is generally celebrated on March 17.
You'll find lots of cool history in this entry. Did you know that Boston has celebrated St. Paddy's Day since 1737?
It's more than enough reason for me to have a Guinness.
"Guinness is Good for You," as the poster to the right states, even for aspiring amateur triathletes.
Thanks for the great holiday Ireland and for sharing it with the world!
