Sheelah's Day
March 18, Monday
Sheelah's Day, also known as Sheelagh's Day, is an Irish cultural holiday celebrated on 18 March which coincides with St. Patrick's Day. While the holiday is no longer widely celebrated in Ireland, there are still associated festivities celebrated throughout the Irish diaspora in Australia and Canada.
Traditionally, Sheelah's Day was celebrated the day after the Feast of St. Patrick and coincided with the Christian festivities. According to Irish folklore and mythology, Sheelah was either the wife or mother of St. Patrick, and the holiday served to commemorate her life.
