How working days are calculated

Two calculators can look at the same country and the same year and return different numbers. That is not usually a bug in either of them — it is the result of four decisions each one has to make, and there is no single correct set of answers.

The basic arithmetic

Every working-day count starts from the same subtraction. Take the number of days in the period, remove the weekends, then remove the public holidays that fall on the remaining weekdays.

Applied to Germany in 2026, that gives:

The last line is the one that causes confusion. A public holiday that lands on a Saturday has already been removed as part of the weekend, so subtracting it again would double-count. This is why a country can gain holidays on paper and lose working days nowhere.

The four decisions behind any number

Once you move past the arithmetic, the variation between sources comes down to four choices.

1. Which days count as the weekend. Almost all of Europe uses Saturday and Sunday, so this is rarely the culprit within the EU — but it is not a universal convention, and a global tool that assumes Saturday–Sunday will be wrong in parts of the Middle East.
2. Which holidays are national. Germany, Spain and the United Kingdom all have holidays that apply in some regions and not others. A national figure has to pick a baseline. We use the holidays that apply everywhere in the country, which means a person in Bavaria or Scotland has fewer working days than the national number suggests.
3. Whether customary days off are included. Christmas Eve is a statutory holiday in Estonia and Lithuania, a normal working day in law but universally a day off in Finland, and an ordinary day in Ireland. Where a day is customary rather than statutory, its treatment is a judgement call.
4. Whether substitute days are applied. In the United Kingdom, a Christmas Day falling on a Saturday moves to the following Monday and a working day is genuinely lost. In Finland it simply disappears. This single difference moves annual totals by several days.

On this site the first two are handled explicitly, the third is shown as a separate category so you can decide, and the fourth is documented per country. Where our source data is known to disagree with national law — as it does for Slovakia and Bulgaria — the country page says so.

How much this varies across Europe

In 2026 the spread across the countries covered here runs from 249 working days in Austria to 254 in Denmark — a difference of 5 days, or roughly 1 working weeks. For a business operating across several European markets, that gap is large enough to matter in capacity planning.

Two things drive that range. Countries with more statutory holidays obviously lose more days, but placement matters just as much: a year in which several fixed-date holidays fall on a weekend hands those days back, unless the country has a substitute rule.

Variation inside a single year

The month-to-month spread is easy to underestimate. In Germany in 2026, July carries 23 working days while May carries only 18 — a difference of 5 days, or 28% more capacity in one month than the other.

If you pay hourly staff a fixed monthly amount, or forecast delivery capacity as a flat monthly figure, that variation is absorbed silently and shows up later as an overrun. The payroll planning guide covers what to do about it.

Edge cases worth knowing

Easter moves, and it moves differently in the east

Good Friday, Easter Monday, Ascension, Whit Monday and Corpus Christi are all anchored to Easter, which shifts by more than a month between years. Bulgaria, Cyprus and Greece follow the Orthodox calculation, so in most years their Easter falls on a different date from the rest of the EU. A calculator that computes Western Easter and applies it everywhere will be wrong for those three.

Some holidays are pinned to a weekday by law

Finnish law fixes Midsummer Day to the Saturday between 20 and 26 June, and All Saints’ Day to the Saturday between 31 October and 6 November. Both are genuine public holidays that never reduce the working-day count, because they are legally required to fall on a Saturday. Croatia’s Corpus Christi is the mirror case: always a Thursday, so it always costs a working day and always creates a bridge-day opportunity on the Friday.

Two holidays can land on the same day

Slovenia’s Independence and Unity Day falls on 26 December, the same date as the second day of Christmas. Slovakia’s New Year’s Day is also the Day of the Establishment of the Slovak Republic. Counting holidays gives a different answer from counting days off, which is why the tables here count days.

What to check before you rely on a number

• Does the figure cover the whole country or a specific region? For Germany, Spain and the UK the difference is material.
• Does your collective agreement treat any customary days — holiday eves in particular — as time off? Those rarely appear in statutory holiday lists.
• Does the country move weekend holidays? Check the country page; the rule is stated explicitly for all 28 countries.
• Are you counting working days or business days? For deadline arithmetic the relevant definition is usually the one written into the contract, and it does not always match the payroll definition.

Every country page on this site shows the full holiday list with the weekday each date falls on, so you can audit the subtraction rather than trust it. Start from the country comparison and drill into whichever market you need.
