Public holidays in Ireland are nationwide days off recognised by the government, when most banks, schools and government offices close and many businesses adjust their hours. They mark historical, cultural, religious or civic occasions and are a standard reference point for supply chain managers timing operations around local closures working with Ireland.

1 fixed-date public holiday is documented for Ireland in the table above, on top of movable observances shown in the live calendar. The exact total varies year to year — some holidays fall on a fixed date, while Easter-based, Islamic-calendar or other lunar observances shift annually, and some are added by regional decree. See the live calendar above for the current list of upcoming and recently observed dates.

Official public holidays in Ireland are enacted by national acts of parliament and published via www.citizensinformation.ie. These non-working days carry legal status for banking, public administration, and employment compliance.

Official national day of Ireland enacted under statutory public holiday acts. It falls on March 17 and carries official non-working status in Ireland — see the statutory holidays table above for its closure impact and official source.

It's Google's own official "Ireland" holiday calendar, embedded directly via Google's public calendar integration — Google serves the data straight to your browser in real time, and we don't store, edit or republish any of it ourselves. For the smaller set of fixed-date national holidays we've individually fact-checked, see the statutory holidays table above instead.

Some do and some don't. Fixed-date holidays repeat on the same calendar day annually, while others follow the Easter calculation, the Islamic lunar calendar, or an "nth weekday of the month" rule — so their date moves from year to year. See how public holidays work above for the full explanation of why, or check the calendar itself for each year's actual date.

When a fixed public holiday falls on a Saturday or Sunday, many governments designate the following Monday as an official substitute non-working day (often termed an 'observed holiday'). Check Ireland's official gazette announcements or the live calendar embed for specific year-by-year substitute day designations.

The live calendar above shows the day of the week next to each date — that's what you need. A holiday landing on a Monday or Friday already gives Ireland a natural three-day weekend; one on a Tuesday or Thursday can often be stretched into four days by taking the single working day in between as leave, sometimes called a "bridge day". Once you've spotted a good date, the Ireland travel guide covers the practical details for planning around it.

Many countries observe additional regional, state or provincial holidays alongside national ones. Ireland is divided into states and provinces — see the Ireland states & provinces directory for region-specific pages with more local detail.

The official holidays table above lists fixed-date national public holidays mandated by law. Dynamic, movable observances (such as Eid or Easter) shift calendar dates annually based on lunar or religious computations — those dates are updated continuously in the live Google Calendar embed below.
