Northern Ireland Bank Holidays 2027

Northern Ireland's bank holidays under the 1971 Act, in 2027

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 Wednesday, March 17 in 2027. The Battle of the Boyne holiday is Monday, July 12.

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.

2027 in Northern Ireland: the same total by a different route

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. 2027 runs 365 days, 52 whole weeks and one day over. It opens and closes on a Friday, 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 2027. That matches 2026 exactly, with the same weekday supply and the same number of weekday holidays. 2028 falls to 250.

Substitute bank holidays in 2027

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 2027:

• Christmas Day falls on Saturday, December 25, and gov.uk lists Monday, December 27 in its place.
• Boxing Day falls on Sunday, December 26, and gov.uk lists Tuesday, December 28 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 2027

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 2027, Northern Ireland's additions on a weekday are St Patrick's Day on Wednesday, March 17 and Battle of the Boyne on Monday, July 12.

The net effect is two fewer working days than England and Wales: 251 against 253.

Where the fixed-date holidays land in 2027

A holiday tied to a calendar date moves one weekday later each year, so the week it breaks changes every year while its date stays put. Against 2026, each of these has moved one weekday on:

• New Year's Day is a Friday in 2027, after a Thursday in 2026, so on this page's count the weekend after it becomes three days off.
• St Patrick's Day is a Wednesday in 2027, after a Tuesday in 2026: a midweek break that leaves two working days on each side of it on this page's count.
• Battle of the Boyne is a Monday in 2027, after a Sunday in 2026, so on this page's count it turns the weekend before it into three days off.
• Christmas Day is a Saturday in 2027, after a Friday in 2026, 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.
• Boxing Day is a Sunday in 2027, after a Saturday in 2026, 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.

Long weekends and four-day breaks in Northern Ireland, 2027

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 2027:

• Friday, January 1 to Sunday, January 3: three days, for New Year's Day.
• Friday, March 26 to Monday, March 29: four days, for Good Friday and Easter Monday.
• Saturday, May 1 to Monday, May 3: three days, for Early May Bank Holiday.
• Saturday, May 29 to Monday, May 31: three days, for Spring Bank Holiday.
• Saturday, July 10 to Monday, July 12: three days, for Battle of the Boyne.
• Saturday, August 28 to Monday, August 30: three days, for Summer Bank Holiday.
• Saturday, December 25 to Tuesday, December 28: four days, for Christmas Day (observed) and Boxing Day (observed).

Midweek holidays in 2027

A Wednesday holiday strands nothing but cuts the week into two short runs of two days each. Northern Ireland's 2027 count has one: St Patrick's Day on Wednesday, March 17.

Northern Ireland month by month, 2027

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.

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 2027

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 2027 it runs from Tuesday, August 31 to Friday, December 24 in the second half of the year: 84 working days, 16 full working weeks and four days.

The first working day of 2027 on this count is Monday, January 4, after New Year's Day. The last is Friday, December 31, which is the latest date a count of working days can end on inside 2027.

Which calendar the 2027 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 2027 the two lists differ on two weekdays.
