When is St Patrick’s Day?
In 2026, St Patrick’s Day falls on Tuesday, March 17, 2026. It is classified here as a Irish public holiday.
History of St Patrick’s Day
St Patrick’s Day is the feast day of Ireland’s most widely known patron saint. Its roots are religious, but its civic meaning has grown through centuries of Irish migration, cultural revival and public celebration at home and abroad.
March 17 is a public holiday across Ireland and a major moment for presenting Irish culture to the world. The day belongs to more than one tradition: Mass and pilgrimage, family time, local parades, language, sport and the distinctive energy of the diaspora all shape its modern character.
The date became an Irish public holiday in the early twentieth century, while today’s large civic festival developed through modern tourism and cultural policy as well as older parish and emigrant traditions. Patrick’s historical mission belongs to late Roman and early medieval Ireland, but many familiar stories are later legend. Parade imagery should not obscure Irish-language culture, pilgrimage and local community ownership.
