âThe Irish and those who wish they were.â. But for 24 hours this Wednesday, that saying is a pot oâ blarney. This St. Patrickâs Day, weâll all be Irish. St. Patrick's Day was originally a Roman Catholic feast day for Ireland âs patron saint, celebrated only in Ireland since before the 1600s.But it evolved into a secular holiday in the 1700s, when Irish immigrants in the US held some of the first St. Patrickâs Day parades.t. Patrickâs revelers thought wearing green made one invisible to leprechauns, fairy creatures who would pinch anyone they could see (anyone not wearing green). People began pinching those who didnât wear green as a reminder that leprechauns would sneak up and pinch green-abstainers.
