“Today’s St Patrick’s Day celebrations have been greatly influenced by those that developed among the Irish diaspora, especially in North America. Until the late 20th century, St Patrick’s Day was often a bigger celebration among the diaspora than it was in Ireland. Celebrations generally involve public parades and festivals, céilithe (Irish traditional music sessions), and the wearing of green attire or shamrocks. There are also formal gatherings such as banquets and dances, although these were more common in the past. St Patrick’s Day parades began in North America in the 18th century but did not spread to Ireland until the 20th century.” To read more click here.
