Saint Patrick's Day, or the Feast of Saint Patrick, is a cultural and religious celebration held on 17 March, the traditional death date of Saint Patrick, the foremost patron saint of Ireland.
The day commemorates Saint Patrick and the arrival of Christianity in Ireland, and celebrates the heritage and culture of the Irish in general. Celebrations generally involve public parades and festivals, céilís, and the wearing of green attire or shamrocks. Christians who belong to liturgical denominations also attend church services and historically the Lenten restrictions on eating and drinking alcohol were lifted for the day, which has encouraged and propagated the holiday's tradition of alcohol consumption.
