Northern Ireland Bank Holidays 2025
Last reviewed: October 14, 2026 · Holiday data: June 23, 2026
The gov.uk list gives Northern Ireland 10 bank holidays in 2025: 10 fall on a weekday and none on a weekend. That leaves 251 working days in 2025. Like the United Kingdom calculator, this page counts Monday to Friday as working days; what changes is the holiday list.
How Northern Ireland differs from England & Wales
Northern Ireland has every England and Wales bank holiday on the same dates and two more: St Patrick's Day on 17 March and the Battle of the Boyne, also called Orangemen's Day, on 12 July. When one of them falls on a weekend, gov.uk lists a substitute day on the following Monday: Monday 18 March 2024 for St Patrick's Day, and Monday 14 July 2025 and Monday 13 July 2026 for the Battle of the Boyne.

- St Patrick's Day (Monday, March 17)
- Battle of the Boyne (observed) (Monday, July 14)

Northern Ireland in 2025: how the calendar falls
Every figure below is computed from the 2025 dates in the table above and the Monday to Friday week, and each rule names the provision or the official list it is taken from. When a date changes, the sentences change with it.
Northern Ireland's bank holidays under the 1971 Act, in 2025
Paragraph 3 of Schedule 1 to the Banking and Financial Dealings Act 1971 is Northern Ireland's list: 17 March (moved to 18 March from a Sunday), Easter Monday, the last Mondays in May and August, 26 December unless it is a Sunday, and 27 December when 25 or 26 December is a Sunday. It is the England and Wales paragraph with 17 March added. New Year's Day, Good Friday, the first Monday in May, 12 July and Christmas Day are not in that paragraph; gov.uk lists all of them for Northern Ireland, and section 1(5) lets the Secretary of State exercise the Act's proclamation powers there.
St Patrick's Day is Monday, March 17 in 2025. 12 July is a Saturday, and gov.uk lists Monday, July 14 for the Battle of the Boyne.
Section 1(4) is the part that bites on deadlines: no one can be compelled to make a payment or do an act on a bank holiday that they could not be compelled to make on Christmas Day or Good Friday, and an obligation falling on one is met on the next day on which it can be compelled. The Act does not name that day.
Why 2025 gives Northern Ireland fewer working days
A year's working days are its weekdays minus the holidays that land on them, and both halves move. The weekday supply depends only on the year's length and the weekday it starts on; the holiday half depends on where each fixed date falls that year. 2025 runs 365 days, 52 whole weeks and one day over. It opens and closes on a Wednesday, so the spare day is a weekday and the year holds 261 of them.
Ten bank holidays in this page's count fall on weekdays, so Northern Ireland has 251 working days in 2025. That is one fewer than 2024 (252). The holidays cost the same number of weekdays both years; the difference is the calendar itself, which supplies one fewer weekday. 2026 lands on the same 251.
Substitute bank holidays in 2025
When a fixed-date bank holiday lands on a Saturday or Sunday, gov.uk publishes a weekday as the substitute, and the substitute is the bank holiday this page's count skips. In 2025:
- Battle of the Boyne falls on Saturday, July 12, and gov.uk lists Monday, July 14 in its place.
The weekend date itself is not in the table: gov.uk lists only the substitute, and that is the date this page counts.
What Northern Ireland's own days cost in 2025
A bank holiday on Northern Ireland's list takes a working day out of the count only when it lands on a weekday that is not also a bank holiday on England and Wales, and a bank holiday on England and Wales that is not on Northern Ireland's list puts one back only when it lands on a weekday. In 2025, Northern Ireland's additions on a weekday are St Patrick's Day on Monday, March 17 and Battle of the Boyne (observed) on Monday, July 14.
The net effect is two fewer working days than England and Wales: 251 against 253.
Where the fixed-date holidays land in 2025
A holiday tied to a calendar date moves one weekday later each year, and two once 29 February has passed. 2025 follows a leap year, so January and February dates move two weekdays against 2024 and everything later moves one:
- New Year's Day is a Wednesday in 2025, after a Monday in 2024: a midweek break that leaves two working days on each side of it on this page's count.
- St Patrick's Day is a Monday in 2025, after a Sunday in 2024, so on this page's count it turns the weekend before it into three days off.
- Battle of the Boyne is a Saturday in 2025, after a Friday in 2024, a weekend day, so the date itself takes no working day on this page's count; the weekend rules above decide whether a weekday is given for it.
- Christmas Day is a Thursday in 2025, after a Wednesday in 2024, so on this page's count it is one of four days off in a row, Thursday, December 25 to Sunday, December 28.
- Boxing Day is a Friday in 2025, after a Thursday in 2024, so on this page's count it is one of four days off in a row, Thursday, December 25 to Sunday, December 28.
Long weekends and four-day breaks in Northern Ireland, 2025
A weekday holiday next to a weekend turns two days off into three; two closures side by side, or one on each side of a weekend, make four or more. That is arithmetic on the dates, so the list moves every year even when the holidays do not. On this page's count, Northern Ireland has seven such breaks in 2025:
- Saturday, March 15 to Monday, March 17: three days, for St Patrick's Day.
- Friday, April 18 to Monday, April 21: four days, for Good Friday and Easter Monday.
- Saturday, May 3 to Monday, May 5: three days, for Early May Bank Holiday.
- Saturday, May 24 to Monday, May 26: three days, for Spring Bank Holiday.
- Saturday, July 12 to Monday, July 14: three days, for Battle of the Boyne (observed).
- Saturday, August 23 to Monday, August 25: three days, for Summer Bank Holiday.
- Thursday, December 25 to Sunday, December 28: four days, for Christmas Day and Boxing Day.
Midweek holidays in 2025
A Wednesday holiday strands nothing but cuts the week into two short runs of two days each. Northern Ireland's 2025 count has one: New Year's Day on Wednesday, January 1.
Northern Ireland month by month, 2025
A month's working days are its weekdays less the holidays on them, so a month with no weekday holiday is set entirely by how its weekdays fall, and every holiday that lands midweek takes one day off the month it sits in.
| Month | Working days, this count | Working days, England and Wales | Weekday holidays |
|---|---|---|---|
| January | 22 | 22 | New Year's Day (January 1) |
| February | 20 | 20 | none |
| March | 20 | 21 | St Patrick's Day (March 17) |
| April | 20 | 20 | Good Friday (April 18) and Easter Monday (April 21) |
| May | 20 | 20 | Early May Bank Holiday (May 5) and Spring Bank Holiday (May 26) |
| June | 21 | 21 | none |
| July | 22 | 23 | Battle of the Boyne (observed) (July 14) |
| August | 20 | 20 | Summer Bank Holiday (August 25) |
| September | 22 | 22 | none |
| October | 23 | 23 | none |
| November | 20 | 20 | none |
| December | 21 | 21 | Christmas Day (December 25) and Boxing Day (December 26) |
The third column counts the same months on England and Wales, so the gap between the two columns is exactly what Northern Ireland's own calendar changes.
Where Northern Ireland counts longest without a break in 2025
The longest run of working days with no weekday holiday inside it depends on how far apart consecutive closures sit, so it moves whenever one fixed-date holiday changes weekday. In 2025 it runs from Tuesday, August 26 to Wednesday, December 24 in the second half of the year: 87 working days, 17 full working weeks and two days.
The first working day of 2025 on this count is Thursday, January 2, after New Year's Day. The last is Wednesday, December 31, which is the latest date a count of working days can end on inside 2025.
Which calendar the 2025 count uses
The count uses the bank holidays gov.uk publishes for Northern Ireland. Section 1 of the Banking and Financial Dealings Act 1971 makes the days in Schedule 1 bank holidays and lets further days be appointed by proclamation. gov.uk publishes a separate list for England and Wales, and in 2025 the two lists differ on two weekdays.
