Business Days in April 2027 for Ireland

April 2027 has 22 working days under the Irish holiday calendar. April 2027 contains no Irish holidays on a weekday. The month covers 30 calendar days, of which 8 are Saturday and Sunday. That count drives invoice cycles, payroll runs, and any contract that defines deadlines as a number of working days in Ireland.

holidays in April 2027

No Irish holidays fall on a weekday in April 2027, so the month loses no working day to a holiday on this calendar.

Ireland April deadlines

Employers pay March's PAYE liability within 14 days after the end of the month, or 23 days on ROS, and a company with a 31 July year end files its CT1 by April 23. A large company whose accounting period began on 1 November pays its first preliminary tax instalment by April 23, the 23rd of the sixth month. Easter Monday is a public holiday, and T2 closes on it and on Good Friday; both fall in April in some years. Easter fell in March in 2027, so April has no Irish public holiday.

Those dates in 2027

Every date named above falls on a working day in 2027 under the Irish calendar. That is worth checking rather than assuming: the same calendar date moves through the week from year to year, so a date that settles cleanly this year may not next year.

Ireland reporting cycles and business-day rules

Revenue sets Irish VAT on two-month taxable periods starting in January, March, May, July, September and November: the return and payment are due by the 19th day of the month after each period, extended to the 23rd for ROS filers. An employer's monthly PAYE liability, shown on a Revenue statement built from the month's payroll submissions, is due 14 days after the end of the month, or 23 days for employers who file and pay on ROS. A company files its CT1 return and pays any balance nine months after the end of its accounting period, on or before the 23rd of the ninth month (the 21st if it does not file and pay electronically). T2, the Eurosystem's real-time gross settlement system, which replaced TARGET2 in March 2023, is open Monday to Friday and, for euro settlement, also closed on 1 January, Good Friday, Easter Monday, 1 May, 25 December and 26 December. It does not close for St Patrick's Day (17 March) or for the Irish public holidays in February, June, August and October, and it does close on 1 May, which is an Irish public holiday only when it is the first Monday in May. Under the European Communities (Late Payment in Commercial Transactions) Regulations 2012, as amended in 2013, 2014 and 2016, statutory late payment interest is the ECB main refinancing rate plus 8 percentage points; between undertakings a contract may vary that interest, provided the result is not grossly unfair to the creditor. A payment date or period that a contract between undertakings sets beyond 60 calendar days must be expressly agreed and not grossly unfair to the supplier. Where the contract specifies no date or period for payment, the payment date falls 30 calendar days after the purchaser receives the invoice, after delivery where the invoice arrives first or its date of receipt is uncertain, or after an acceptance or verification procedure where one applies and the invoice arrives no later than it. Interest runs from the day after the payment date.

April 2027 working days compared by country

Working-day counts vary across countries because each country observes its own public holidays. The table below shows April 2027 under 11 of the site's 25 holiday calendars; the summary above gives Ireland's own count.

How April 2027 compares year over year

April 2026 had 20 working days, so April 2027 has 2 more working days year over year. On the surrounding months, March 2027 has 20 working days and May 2027 has 20. Looking forward, April 2028 has 18 working days under the same Irish holiday calendar.

Using this calculator in Ireland

Count the 22 business days of April 2027 against Revenue's dates when one is near: VAT for each two-month period is due by the 19th day of the following month, or the 23rd for ROS filers; an employer's PAYE for a month within 14 days after its end, or 23 days on ROS; and a company's CT1 return and balance on or before the 23rd of the ninth month after its accounting period ends (the 21st if it does not file and pay electronically). A euro payment that settles through T2 cannot settle on 1 January, Good Friday, Easter Monday, 1 May, 25 December or 26 December, although T2 does not close for St Patrick's Day or for the Irish public holidays in February, June, August and October. Where a contract specifies no date or period for payment, the Late Payment Regulations 2012, as amended, put the payment date 30 calendar days after the purchaser receives the invoice, after delivery where the invoice arrives first or its date of receipt is uncertain, or after an acceptance or verification procedure where one applies and the invoice arrives no later than it.

How April 2027 is shaped

The headline count answers how many working days April 2027 contains. It does not answer where they sit, and for anything measured in consecutive days rather than cumulative days that second question is the binding one. What follows is derived entirely from the Irish holiday calendar and a working week that treats Saturday and Sunday as the weekend, with no assumption about how any particular obligation behaves.

A 30-day month opening the second quarter

April runs 30 days and opens Q2. It shares its weekday alignment with July in every year, so the two months have the same internal shape before holidays are applied, and any difference between their working-day counts comes entirely from closures rather than from the calendar. April is also one of the four months that begin a quarter, which puts its first working day at the head of a reporting period.

In April 2027 that comes to 22 working days across 30 calendar days, against 20 in March 2027 and 20 in May 2027.

A late-week start

The month opens on the fourth working day of the week, which leaves only a short tail before the first weekend. The practical consequence is that the month's first genuinely full working week does not begin on the 1st at all. Anything scoped as "we have the first week to do this" has materially less time than the phrase suggests, and the shortfall is visible in the opening run below.

The opening stretch runs from Thursday, April 1 to April 2, two working days before the first break. April 2027 carries 22 working days in total, so that opening block is 9% of the month's working capacity.

Five working stretches

April splits into five working stretches. That is the ordinary shape of a month whose only interruptions are its weekends, and it means the month's internal boundaries are all predictable a year in advance: nothing here depends on a holiday date moving.

The working days of April 2027 arrive in stretches of 2, 5, 5, 5, and 5 days. The longest unbroken stretch runs five days, from April 5 to April 9. A task needing more consecutive working days than that cannot be completed inside a single stretch, whatever the month's total looks like.

The month is back-loaded. It opens with two consecutive days and closes with five, so the room is at the end rather than the start. That is the safer of the two imbalances, because a slip has somewhere to go, but it also makes the opening week a poor sample of the month.

Two weekdays occur five times

Thirty days is four seven-day cycles plus two, so a 30-day month has exactly two weekdays occurring five times and five occurring four times. Here they are Thursday and Friday. The pair is always consecutive, because the surplus days are the first two of the month repeated at its end.

All of them are working days here, so the surplus lands entirely on the working week: Thursday and Friday each occur 5 times. Had the surplus fallen on the weekend instead, the same month would carry 20 working days rather than 22.

A month with no closures, and a long one

April 2027 contains no Irish holiday on any date, working or otherwise. A month with no closure loses working days only to weekends, so its count is set entirely by the weekday it opens on and its length, and here both work in the month's favour: 22 working days across 30 calendar days.

Months at this end of the range are the ones worth reserving for work that needs consecutive days rather than cumulative days. The constraint that usually breaks a long run, a closure landing mid-week, is absent, so the month's structure is entirely weekend-driven and repeats on a seven-day cycle.

A closure sits just outside the month

April 2027 contains no Irish closure of its own, but one sits within a week of its edge. A closure just outside a month still reaches into it: work displaced from the closed day lands on the working days beside it, and those are inside April whichever side the holiday falls on.

Looking outside the month, the last was Easter Monday on March 29, 2027, 3 calendar days before April began and the next is May Day on May 3, 2027, 3 calendar days after it ends.

Across the whole of 2027 the Irish calendar puts ten closures on working days, of which none falls in April. That ratio, rather than the raw count, is what tells you whether a month is carrying more than its share of the year's downtime.

The working month and the calendar month end together

The month's last calendar day is also the last working day of a week. Month-end and week-end fall on the same date in April 2027, which is the one alignment where a weekly close and a monthly close cannot be separated. Everything queued for both runs on the same day, and there is no working day left in April to absorb a slip.

The last working day of April 2027 is Friday, April 30. Counting back from there, the third-to-last is Wednesday, April 28, two calendar days before the month closes.

The quarter opens here

April is the first month of Q2. An opening month sets the baseline the rest of the quarter is measured against, and it is the one month where a slip has two further months to be absorbed in. Quarterly targets divided evenly by three ignore the fact that the three months rarely carry equal working-day counts.

Across the whole quarter there are 63 working days, of which 22 fall in April. The other two months carry May 2027 with 20 and June 2027 with 21. It is the largest of the three, so work deferred out of April lands in a month with less room than this one had.

The week's first working day is the scarcest

The first working day of the week is the one April gives least often. Anything anchored to the start of the working week (a weekly kickoff, a Monday-morning cutoff, a start-of-week batch) fires fewer times this month than the calendar count suggests, because a closure has taken one of them out.

Counted as worked rather than as occurring, April 2027 gives Monday 4, Tuesday 4, Wednesday 4, Thursday 5, and Friday 5. A weekly commitment pinned to a particular weekday fires that many times in the month, which is the number a rota needs and not the one the calendar shows.

One of the year's longest working months

No month of 2027 carries more working days than April under the Irish calendar. A year's working days are not distributed evenly across its twelve months, and the gap between the longest and the shortest is wide enough that a target divided by twelve is wrong in both directions.

2027 carries 251 working days in total under the Irish calendar. The longest month of the year is April 2027 with 22 and the shortest is February 2027 with 19, a spread of 3. April ranks 1st of the twelve with 22.

Ireland closures across the year

A month's working-day count only means something against the country's whole calendar. Two countries that share a weekend and happen to have the same closure-free month can still run very different years, and Ireland is placed as follows.

Across 2027 the Irish closures fall 5 in Q1, 2 in Q2, 1 in Q3, and 2 in Q4. Every holiday in the Irish data for 2027 falls on a working day, so the country's holiday count and its working-day loss are the same number this year, which is not usually the case.

The longest uninterrupted run in the 2027 calendar sits between August 2, 2027 and October 25, 2027, 84 calendar days with no Irish closure in between. Stretches like that are where multi-week work belongs, and they move from year to year whenever a movable holiday does.

Where the month sits in the year's closure pattern

Closures are not spread evenly across a calendar year. They cluster around fixed anniversaries and around whichever lunar or movable feasts a jurisdiction observes, so two adjacent months can carry very different loads, and the Irish calendar is no exception.

2027 opens its Irish closures with New Year's Day on January 1, 2027 and ends them with St Stephen's Day (additional) on December 27, 2027. The densest month of the year is March 2027 with three closures on working days.

A materially longer month than last year

April 2027 carries 2 more working days than April 2026 did (22 against 20). A swing of two or more days in the same month between adjacent years is large: it means the weekday alignment moved and a closure changed position, not just one of the two. Any run-rate carried forward from last year understates this month.

April opens 2026 on a Wednesday, 2027 on a Thursday, and 2028 on a Saturday. That movement, one weekday in a common year and two after a leap day, is what makes the three counts differ. The count of closures on working days differs between the two years as well, so alignment is not the only thing moving. Looking ahead, April 2028 carries 18 working days.

Where the month's anchor dates fall

Two of the common monthly anchor dates in April 2027 land outside the working week or on a closure. The table below resolves each one against the Irish calendar, together with the first working day on or after it.

The final column is arithmetic, not a legal conclusion. Whether an obligation actually moves when its date is not a working day depends on the instrument that sets it, and this site does not assume a shift rule for any jurisdiction. Where a rule is known it is stated in the holiday data methodology and on the country page it applies to.

Net terms dated in April 2027

An invoice dated the 1st of April on calendar-day Net 30 terms comes due on May 1, 2027, which is not a working day under the Irish calendar. A term counted in calendar days can land anywhere in the week, and roughly two days in seven it lands somewhere nothing settles, which is the ordinary reason a payment shows as late by a day or two without anyone being late.

Invoice dateNet 30, calendar daysNet 60, calendar days
Dated April 1May 1, 2027 (rolls to May 4, 2027)May 31, 2027

Dated April 30May 30, 2027 (rolls to May 31, 2027)June 29, 2027

Net 30 and Net 60 are commercial conventions rather than statutory periods, and both are counted here in calendar days, which is how they are almost always written. Where a contract counts in working days instead, use the between-dates calculator with the Ireland calendar selected, because the two produce different dates whenever a closure falls inside the term.

Frequently Asked Questions

How many business days are in April 2027 under the Irish holiday calendar?
April 2027 has 22 working days under the Irish holiday calendar. The month spans 30 calendar days, of which 8 fall on a weekend and 0 are Irish holidays that land on a weekday. The remaining 22 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which Ireland holidays affect April 2027?
April 2027 contains no Irish holidays that fall on a weekday, so on this calculator's holiday set the month loses no working day.
Why is St Brigid's Day included from 2023 onward?
S.I. No. 50 of 2022, made under the Organisation of Working Time Act 1997, prescribed St Brigid's Day as Ireland's tenth public holiday from 2023: the first Monday in February each year, or 1 February itself when that falls on a Friday. The explanatory note to the regulations ties the day to Imbolc and St Brigid, and names Monday 6 February 2023 as the first.
What happens when an Irish public holiday falls on a weekend?
It stays a public holiday on its own date: the Organisation of Working Time Act 1997 moves none of them. The employee's benefit becomes a paid day off within a month, an extra day of annual leave or an extra day's pay, and the Workplace Relations Commission states that there is no legal entitlement to have the next working day off. The Banking & Payments Federation Ireland's bank-holiday lists still close the banks on the next free weekday after each weekend public holiday they cover. Government offices close it after a Sunday holiday (civil-service Circular 5/1984); after a Saturday one the circular only lets a department grant its staff a day off. This calculator counts that weekday as closed, marked (additional), where banks and Government offices both close it, which after a Saturday holiday means a department's own closure list shows it closed, and as a business day otherwise. Easter Monday, St Brigid's Day and the Monday holidays in May, June, August and October always fall on a weekday.
Why does the business-day count vary year to year?
Two things shift the monthly count for Ireland. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Irish holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. April 2026 had 20 working days, so April 2027 has 2 more working days year over year.
When is the last working day of April 2027?
The last working day of April 2027 under the Irish calendar is Friday, April 30. The month's last calendar day is Friday, April 30, so the two are the same date this year. Counting back, the third-to-last working day is Wednesday, April 28.
How many working days in a row does April 2027 offer?
April 2027 has 22 working days in total, but they do not run consecutively. They arrive in five stretches of 2, 5, 5, 5, and 5 days, so the longest unbroken run is five days, from April 5 to April 9. No working day in the month is isolated between two closures.
