Common questions
How many working days does 2027 have in Ireland?
251 — 261 Mon–Fri weekdays minus 10 national holidays that land on a weekday. Regional and local holidays sit outside the national set and would lower the number further where they apply.
How many working days is that per month, on average?
About 20.9 per month — but the spread matters more than the average: 65 working days in Q3 against 60 in Q1. A plan that assumes a flat month overcommits exactly where the calendar is thinnest.
Does this include vacation or booked time off?
No — this is the ceiling the calendar sets before anyone books leave. A team’s real capacity subtracts each person’s time off and part-time arrangement from these days; that is what the capacity calculator computes for a whole team, per member country.
Rule source: Organisation of Working Time Act 1997 s.21, rules last verified 2026-08-03. Good Friday is not a statutory public holiday in Ireland and is excluded, though many workplaces close. St Brigid's Day counts from 2023, the year it was introduced. A holiday landing on a weekend is shown on the following working day, but the Organisation of Working Time Act lets an employer settle the entitlement with an extra annual-leave day or an extra day's pay instead of a substitute day, so that date is modelled and the team may well work it.
Now subtract your actual team
251 days is the calendar’s ceiling for one person in Ireland. A real team spans countries, books leave, and works part-time — the calculator does that arithmetic for your headcount in seconds, no account.
