Remembered on 17 March

Liturgical rank: Commemoration · Liturgical colour: white
Patron of: Ireland and Nigeria
Who they were
Patrick was a Roman Briton, born around 385, who was taken to Ireland as a slave as a teenager, escaped, and later went back as a bishop and missionary. He died on 17 March, traditionally in 461, at Saul in County Down.
Two short texts attributed to him survive: a Confession and a letter to the soldiers of Coroticus. They are among the oldest documents written in Ireland and are the reason we know anything first-hand about him at all. The shamrock and the snakes are later tradition, not his writing.
Why they are remembered
He is the patron saint of Ireland and the day is a national holiday there, a bank holiday in Northern Ireland, and a public holiday in Newfoundland and Labrador and in Montserrat. In the United States it is not a federal holiday, though the parades are older than most of the Irish ones.
17 March falls inside Lent, and when it clashes with Holy Week the Irish bishops move the church celebration, while the civil holiday stays put.
In the liturgy
In the General Roman Calendar 17 March is a commemoration, in white. In Ireland it is a solemnity, by the national calendar.

How to read the rank and colour
"Commemoration" and the colour white come from the General Roman Calendar: the rank decides the celebration's weight and whether it drops out in a year it falls on a Sunday or strong season; the colour sets the vestments worn at that day's Mass.
Where this page comes from
Date, rank and colour come from the LitCal API (Apache-2.0 code, a community project, not an official publication of the Holy See). The biographical facts come from Wikidata (CC0). Checked on 7 October 2026.
What this page is not
This page is not an official publication of the Holy See and does not reproduce the Roman Martyrology: every descriptive line is written by us, from open facts. For the official liturgy of the day, check your diocese or parish.
What canonization means
Canonization is the act by which the Church officially declares someone a saint who may be publicly venerated anywhere. It is the final step of a longer process, which usually passes through beatification and requires a recognised miracle.
Understanding Saint Patrick's place in the calendar
What does the rank "Commemoration" change in practice for Saint Patrick?
An optional memorial may or may not be celebrated, at the celebrant's choice: that is Saint Patrick's rank, the most common one among the calendar's saints. The day's liturgical colour is white.
Is Saint Patrick in the General Roman Calendar or just tradition?
Saint Patrick has a fixed date in the General Roman Calendar, the calendar that applies to the whole Catholic Church — so the date and rank shown here do not depend on where someone lives. Local calendars (a diocese, country or religious order) can raise the rank, but the base is the same everywhere.
Where does Saint Patrick's reputation as a patron come from?
Saint Patrick is invoked as patron of Ireland and Nigeria. This kind of patronage almost never comes from a single document: it is the sum of popular tradition, the saint's life story and, sometimes, a formal decree from a diocese or a trade, built up over centuries.
Words on this page
Patron saint
A saint chosen as the protector of a place, profession, cause or person, usually by popular tradition or formal church decree. The same saint can patronise several things at once, through a link to their life or to the legend that grew up around it.
Canonization
The act by which the Catholic Church officially declares that a deceased person is a saint and may be publicly venerated anywhere. It is the final step of a longer process, which usually passes through beatification and requires a recognised miracle.

Obligatory and optional memorial
An obligatory memorial must be celebrated wherever no higher-ranking date falls that day; an optional one may or may not be celebrated, at the choice of whoever presides at Mass. Most saints on the calendar carry a memorial, not a feast or solemnity, which is why many pages in this module show this rank.
Liturgical colour
The colour of the vestments worn at Mass, marking the character of the celebration: white for feasts and joy, red for martyrs and the Holy Spirit, green for Ordinary Time, purple for penance (Advent and Lent), and rose on two specific Sundays of the year.
Liturgical season
Each period of the church year (Advent, Christmastide, Lent, the Easter Triduum, Eastertide, Ordinary Time) has its own tone and colour, and that season can suppress a saint's memorial that falls within it. That is why the same civil-calendar date can, in different years, fall inside or outside a strong season.
Martyrology
The official book that lists, day by day, every saint and blessed recognised by the Catholic Church, with biographical facts and an account of their death or life. The text of the Roman Martyrology (2004 edition) belongs to the Libreria Editrice Vaticana and is not reproduced on this site; the facts used here come from open sources.
