Which 2027 public holidays fall on a Saturday or Sunday?

In 2027 there are two national public holidays on a Saturday, 1 May and 25 December, and one on a Sunday, 15 August. They are not the same for an employer: the one on a Sunday moves to the Monday by law, while the one on a Saturday means checking who is off that day and whether they are owed another in exchange. The official calendar is already published in the BOE, so all of this can be settled in the working calendar before the year begins.

Quick answer

2027 national holiday	Day of the week	What it means for the employer
1 May, Labour Day	Saturday	Anyone off on Saturdays may be entitled to another day (National High Court, 2026).
25 December, Christmas Day	Saturday	Same as 1 May. Neither can be swapped out.
15 August, Assumption	Sunday	The day of rest moves to Monday 16, unless the community replaces it with another holiday.

The rest of the 2027 national holidays fall on weekdays: New Year’s Day and Good Friday on a Friday, National Day (12 October) on a Tuesday, All Saints’ Day and Constitution Day on a Monday, and the Immaculate Conception on a Wednesday.

Where these dates come from

The calendar of public holidays is published in the BOE every year. The 2027 one came out through the Resolution of 8 October 2026 of the Directorate-General for Employment (BOE-A-2026-21254), which sets out the national holidays, those of each autonomous community and those of Ceuta and Melilla. Each municipality’s two local holidays are not in there: they are published in the regional or provincial bulletin. Our 2027 work calendar for Spain lists each community’s holidays with the day of the week.

The paid, non-recoverable national holidays are listed in article 45 of Royal Decree 2001/1983. Some are fixed and cannot be moved, such as 1 May or 25 December. Others can be replaced by the communities with a traditional holiday of their own, such as Epiphany or Maundy Thursday. That is why one community’s calendar is not identical to its neighbour’s, even though the major dates coincide.

The two Saturdays: 1 May and 25 December

1 May and 25 December 2027 are national holidays that cannot be swapped out, so they fall on a Saturday across Spain. For a workforce that works Monday to Friday, a holiday on a Saturday is absorbed by the weekly rest and, if nobody does anything, it is simply lost.

That is the point that has shifted in recent months. Since May 2026 the National High Court (Audiencia Nacional) has been handing down rulings that require an extra day off for anyone who loses the holiday because it coincides with their Saturday rest. It follows the line the Supreme Court already applied to shift workers and to those who take a fixed day off during the week: weekly rest and the public holiday are two separate rights, and one cannot absorb the other. These rulings can be appealed, and the Supreme Court has not yet ruled on the specific case of Saturdays, so the case law is not settled. But an employer that fails to compensate is exposed to a claim backed by those rulings. The full picture, with the rulings and the nuances by sector, is in whether a public holiday that falls on a Saturday is compensated.

For anyone who does work on 1 May or 25 December, the rule is different: they are paid their salary and, on top of that, either a day off or those hours with a minimum premium of 75%. It is set out in article 47 of Royal Decree 2001/1983 and can be improved by the collective agreement.

Sunday 15 August moves to the Monday

15 August 2027, the Assumption, falls on a Sunday. In this case there is no need to argue over compensation: article 37.2 of the Workers’ Statute (Estatuto de los Trabajadores) itself moves the day of rest to the following Monday when a national holiday falls on a Sunday. For 2027 that Monday is 16 August, which appears as a public holiday in the BOE calendar for several communities.

The nuance is that communities can waive that Monday and put a traditional holiday of their own in its place. So 16 August will be a public holiday in some territories and not in others, and it pays to check your community’s 2027 work calendar before taking it for granted.

Don’t forget the regional and local holidays

The national holidays are only part of the picture. Each community sets its own holidays and each town council its two local ones, and any of them can also fall on a Saturday or Sunday. A site in one province may have a regional holiday on a Saturday that does not affect a site in another, and local holidays vary even between neighbouring municipalities.

That is why planning 2027 is not just a matter of noting 1 May and 25 December. You have to build each site’s calendar with its national, regional and local holidays, see which fall on a weekend and decide in advance what to do with each one. The annual working calendar (art. 34.6 of the Workers’ Statute) is the document where this is finalised.

How Cleverfy solves it

Cleverfy is time-tracking and working-hours software for SMEs and self-employed professionals. It builds each site’s working calendar and cross-checks it against clock-ins, so public holidays on a Saturday or Sunday stop being a loose end.

• Calendar per workplace that imports national, regional and local holidays by municipality, with no need to type them in by hand.
• Flags the holidays that fall on a weekend, so you can spot them at a glance when planning the year.
• Compensatory day recorded with its reason, its approval and the date it is taken, which is the evidence the National High Court requires.
• Detects who has clocked in on a public holiday and leaves it pending review, to pay it with a premium or compensate it with rest according to your collective agreement.
• Hours report with the holidays marked day by day, ready for a claim or for a Labour Inspection.

You can see the rest on features.

Conclusion

Of the 2027 national holidays, 1 May and 25 December fall on a Saturday and 15 August on a Sunday. The Sunday is resolved by law, moving to Monday 16; the two Saturdays are the ones that call for a decision, because an employer that fails to compensate the holiday for someone off that day risks a claim backed by the National High Court. To that you have to add the regional and local holidays that fall on a weekend at each site. With the BOE calendar already published, the sensible move is to finalise it now and get it on record, rather than wait for someone to claim it in August.
