We've all wondered at some point whether a day is a holiday or not. It's a question that can sometimes be very difficult to answer, and can even cause some pretty serious problems at work, in our studies, or when planning a trip. How can we solve these kinds of problems? It's very simple. We just need to consult the official publications offered to us by the state and, where applicable, by each autonomous community and each municipality.
These are documents in which we can consult both the laws that are put into effectsuch as changes to school dates, work calendars, national, regional, and local holidays, and different academic years. These publications are disseminated primarily through the Official State Bulletin (BOE) and from the official bulletins of each autonomous community and each province or municipality.
This type of official documentation, which varies depending on the autonomous community and country, is published daily and usually consists of several pages. However, you don't need to read them all. Simply look at those content hub that you're actually interested in: for example, the list of public holidays, the resolution on the school calendar, or the decree approving the calendar of an autonomous community. In fact, there's a lot of redundant information whose meaning we won't even know, so we shouldn't focus on it if all we want to know is whether a day is a holiday.
These publications clearly specify key aspects of Work calendarThis document outlines the maximum number of public holidays per year, whether these holidays are paid or unpaid, which holidays are national and cannot be substituted, which holidays can be changed by the autonomous communities, and how many days correspond to local holidays set by each municipality. Thanks to this system, anyone can officially check which days are working days and which are non-working days.
Furthermore, the autonomous communities have the power to adapt certain holidays to their own traditions. Within the general limit of public holidays, they can declare holidays specific to their territory and, in some cases, replace certain national holidays that can be substituted. They can also decide whether to move some holidays that fall on weekdays to Monday or whether to keep them on the exact date, which explains why sometimes a day is a holiday in one community and a working day in another.
What specific information about public holidays is officially published?

Several types are distinguished in the official bulletins Public holidaysOn the one hand, there are the national holidays that are paid and non-recoverable, including some dates observed throughout the country that the autonomous communities cannot replace. Alongside these are other national holidays that the communities can substitute with celebrations that are traditional in their territory.
On the other hand, the total number of public holidays is set, which cannot exceed a general annual limit, and which also includes two days of local festivities These local holidays are approved by the town councils and published in the official gazette of the autonomous community or, where applicable, in the official gazette of the province. This ensures that anyone can check which specific days are non-working days in their city or town.
Labor regulations also provide for the possibility of move holidays to Monday When a holiday falls on a Sunday, the Government may decide to move national holidays that can be moved, and the autonomous communities may exercise this same power within their jurisdiction. Similarly, if a community does not have enough Sundays to accommodate all its traditional holidays, it may exceptionally add one more holiday, which will be made up later, respecting the overall maximum number of days established.
The bulletins also publish the resolutions that order the publicity of all national, regional and local holidays, in order to facilitate the general knowledge of the work calendar throughout the territory. This publication usually includes an annex with the specific dates for each autonomous community and for the autonomous cities, accompanied, where appropriate, by explanatory notes that explain particularities of some territories, such as island or regional holidays.
In this way, not only are state-level festivals known, but also the specific adaptations in each community (for example, replacing one holiday with another traditional one in a specific area or declaring a day off). For citizens, this translates into a very useful tool for planning vacations, exams, competitive exams, travel, or any activity that depends on working and non-working days.
Practical example: the BOE and the regional bulletins

To give you an idea, in Extremadura there is the BOE, a document in which a few months ago we were able to read both the start date and the end date of the different types of courses. In this way, even before finishing the previous call, we could already know the dates of the next course. A insights Quite useful for educational centers, candidates for competitive examinations, and teaching staff.
To this example we can add how the regional bulletinsThese decrees, which are published annually, detail the regional holidays and include the applicable national holidays, also indicating if any fall on a Sunday and are moved to the following Monday. Furthermore, it is noted that local holidays determined by each municipality will be added to these days.
In many cases, the bulletins include specific notes about certain areas, such as in some communities where additional holidays are established for specific territories, or where a particular day is replaced by another that is deeply rooted in the local tradition. All this information is clearly reflected in the official text, making it easier for workers, educational institutions, and businesses to plan accordingly. annual planning without relying on rumors or unofficial schedules.
Today, both the BOE (Official State Gazette) and the regional bulletins allow for the following: advanced searches Searchable by keywords (e.g., āwork calendar,ā ālocal holidays,ā or āschool calendarā) and by date, which saves a lot of time. These publications also often include downloadable PDF versions and can even be integrated into other resources such as printable calendars or website widgets.
In addition to official publications, there are tools that collect and organize information from newsletters so that users can consult them. work calendars by autonomous community, province, or municipality. Many of these platforms offer a general calendar for Spain, listings by autonomous community, links to calendars for subsequent years, and details of local holidays in each town, always based on legislation and official resolutions.
Remember that these documents not only inform us about the dates, but also about everything that has to do with the state (or the autonomous community) and the educational centers. In short, an excellent source of data which will be very useful for you to know for sure which days are holidays, how they are distributed between the national, regional and local levels, and what legal rules apply to each of them, avoiding confusion and allowing for better personal, academic and work organization.
