Public holidays in the Republic of Ireland

These are the public holidays observed in Ireland. Public holidays in Ireland (as in other countries) may commemorate a special day or other event, such as Saint Patrick's Day or Christmas Day. On public holidays (sometimes referred to as bank holidays), most businesses and schools close. Other services, for example, public transport, still operate but often with reduced schedules.

The ten public holidays in Ireland each year are as follows:

Where a public holiday falls on a Saturday or a Sunday, or possibly coincides with another public holiday, it is generally observed (as a day off work) on the next available weekday, even though the public holiday itself does not move. In such cases, an employee is entitled to at least one of the following (as chosen by the employer): a day off within a month, an additional day's paid annual leave or an additional day's pay. The usual practice is, however, to award a day off on the next available weekday.

History
The United Kingdom Bank Holidays Act 1871 established the first Bank holidays in Ireland. The act designated four Bank holidays in Ireland:
 * Easter Monday
 * Whit Monday
 * First Monday in August
 * Saint Stephen's Day

As Good Friday and Christmas Day were traditional days of rest and Christian worship (as were Sundays), therefore it was felt unnecessary to include them in the act as they were already recognised as common law holidays.

In 1903, Saint Patrick's Day became an official public holiday in Ireland. This was due to the Bank Holiday (Ireland) Act 1903, an Act of Parliament introduced by the Irish MP James O'Mara.

In 1939, the Oireachtas passed the Holidays (Employees) Act 1939 which designated the public holidays as:
 * Saint Patrick's Day
 * Easter Monday
 * Whit Monday
 * First Monday in August
 * Christmas Day
 * Saint Stephen's Day

The Holidays (Employees) Act 1973 replaced the Whit Monday holiday with the first Monday in June. New Year's Day was added by Statutory instrument in 1974. The October Holiday was added in 1977. The first Monday in May (commonly known as May Day) was added in 1993 and first observed in 1994.

The Organisation of Working Time Act 1997, among other things, transposed European Union directives on working times into Irish law. Schedule 2 of the Act specifies the nine public holidays to which employees in Ireland are entitled to receive time off work, time in-lieu or holiday pay depending on the terms of their employment.

In 2022 only, Friday 18 March was a public holiday, to recognise the efforts of the country during the COVID-19 pandemic.

In 2023, Saint Brigid's Day (Imbolc) became a public holiday, to mark both the saint's feast day and the seasonal festival. It is observed on the first Monday of February, or on 1 February if it falls on a Friday. A government statement noted that it is the first Irish public holiday named after a woman, and "means that all four of the traditional Celtic seasonal festivals will now be public holidays".

Once-off public holidays
The power to introduce an additional public holiday is provided for in the Organisation of Working Time Act 1997 and the Minister for Enterprise, Trade and Employment may introduce a new public holiday by regulation. To date, three once-off public holidays have been introduced under the Act via Statutory Instrument. These were:

Primary schools
