The 2025 work calendar in Spain will once again combine two prominent dates of the year in December: Spanish Constitution Day and the Immaculate Conception Holiday. Both days are listed as national holidays and are usually the last before Christmas. However, the order of dates in next year’s calendar will change the usual configuration of the so-called “Constitution Bridge”, as this time it will coincide with Saturday, reducing the possibility of enjoying several consecutive days of rest.
The Spanish Constitution, approved on December 6, 1978, is celebrated every year as the anniversary of the entry into force of the democratic system. Since then, December 6 has been recognized as a holiday throughout the national territory. The second date indicated, December 8, corresponds to the Feast of the Immaculate Conception, a festival of religious origin that is also observed throughout the country. In years when both dates fall on workdays, a long bridge usually forms, providing an opportunity for rest for the majority of workers.
The work calendar designates Saturday, December 6 and Monday, December 8 as national holidays. The requirement means that only one of the two days this year will provide a break from the work week for most workers. Thus, the weekend that will coincide with Constitution Day will not generate an additional day off, while the holiday of the Immaculate Conception, which falls on a Monday, will allow for a short, extended rest of three consecutive days.
Constitution Day falls on a Saturday and reduces the bridge options
December 6, 2025 will be a Saturday and, as is the case every year, Constitution Day will be celebrated throughout Spain. Since it falls on the weekend, the holiday will not mean an extra day off for those who work Monday through Friday. Current regulations do not include the automatic transfer of national holidays when they fall on a Saturday or Sunday, so autonomous communities cannot adjust this situation unless they make some adjustments of their own in their regional calendar.
Companies, public administrations, and educational centers will resume their normal activities on Friday, the fifth of this month, and will resume their work on Tuesday, the ninth of that month. The result is a weekend with vacation included, but not extended, for a large proportion of workers. This circumstance will also affect the movement of passengers and the organization of commercial and tourist activities, which on other occasions benefit from a greater number of consecutive vacation days.
The fact that December 6 falls on a Saturday reduces the possibility of planning long trips or staying outside the usual place of residence. However, many citizens will be able to take advantage of the proximity of the holiday on Monday to organize short-term activities or trips during the weekend itself.
Immaculate Conception, the holiday that allows for a long royal weekend
Monday 8 December 2025, the Day of the Immaculate Conception, will be a holiday throughout the national territory and will be the only opportunity this month to enjoy a real long weekend. By placing it on a workday, it will allow three consecutive rest days – Saturday, Sunday and Monday – to be linked to those who work from Monday to Friday. This will be the only long weekend in December, as the rest of the month’s holidays are not directly related to working days.
Although the traditional “Constitution Bridge” will not take effect in 2025, the fact that the Feast of the Immaculate Conception falls on Monday will allow most workers to enjoy a three-day rest. This combination of a Saturday holiday and a non-working Monday forms the last long weekend of the year, before Christmas and the conclusion of the working calendar. Overall, December 2025 will offer two consecutive national holidays on the calendar, but only one of them will generate an effective nationwide bridge.
