About this holiday
St Patrick's Day on March 17 honours the patron saint of Ireland and commemorates the arrival of Christianity in Ireland in the fifth century. Originally a religious feast day, it has become a global celebration of Irish culture — marked by parades, wearing green, and festivities in cities from Dublin to New York to Sydney. The Chicago River is famously dyed green each year for the occasion.
