In 2026 the Día de la Constitución (6 December) falls on a Sunday and the Inmaculada Concepción (8 December) on a Tuesday. The 2026 national list (BOE, Resolución de 17 de octubre de 2025, BOE-A-2025-21667 ↗) marks 8 December “Fiesta Nacional no sustituible” in all 19 communities. It has no row for Sunday 6 December itself, and a row “7 Lunes siguiente al Día de la Constitución Española” marked “Fiesta Nacional respecto de la que no se ha ejercido la facultad de sustitución” for ten communities. Where Monday 7 is not a holiday, many people take it as a day of leave to make a Saturday–Tuesday break (a “puente”). Municipalities can add local holidays, so this table is a guide, not payroll advice.

Comunidad de Madrid · 2 listed events
Monday 7 December is a holiday in Comunidad de Madrid (BOE annex), so the long weekend runs Saturday to Tuesday with no leave needed. Local holidays may add to this.

On Friday 4 December 2026 at 19:00 the Iván de Vargas public library in central Madrid holds the December session of its Tolkien Universe club. The group meets on the first Friday of each month, this season on 2 October, 6 November and 4 December, to share readings, interpretations and curiosities about the work of J. R. R. Tolkien. The first book was The Hobbit. The club is for adults over 18, free, and entry is open until the room is full. The library does not provide the books, and the listing gives no end time, so we estimate about ninety minutes. A themed book club is an easy way to meet people alone, because you arrive with a shared story and a ready subject, and in a winter city the warm library is a good place to spend a Friday evening. «Un club para adentrarse en el universo literario de J. R. R. Tolkien» Starts 19:00, ends about 20:30. Source: Madrid city open data — Agenda de actividades y eventos (Ayuntamiento de Madrid, datos.madrid.es).
Going alone? What to expect. Public events like these are mostly drop-in or small groups, so arriving solo is normal. Arrive ten minutes early, note the official start time, and keep an exit plan.

Cataluña · 1 listed event
Cataluña is not on the BOE list for Monday 7 December, so Monday is normally a working day there and the “puente” is a day of leave. Tuesday 8 December is a holiday everywhere. Check your regional and local calendar.

Cook seasonal, local food for the longest nights: a root-vegetable and mushroom pie, parsnip and pear soup, Swedish Saint Lucia buns, and a hot spiced wassail to share at the end. Free; places may need booking.

Jorge Casasnovas guides a listening session on Aragonese folk music, playing selected recordings with commentary on the genre's techniques, emotional character and history, from figures such as José Antonio Labordeta. Entry is free until the room is full. Guided listening is relaxed and gives you something to talk about with your neighbours.

Bilbao's municipal wind band, conducted by Iñaki Urkizu, plays its season programme Caminos in the hall of the city conservatory. Municipal band concerts draw a broad local audience and are easy to attend alone; check the listing for ticket details.

On Saturday 5 December 2026 at 19:00 a Candlelight concert plays the songs of Coldplay against those of Imagine Dragons in the Iglesia de la Encarnación in Bilbao. The Spanish listing names pieces such as Clocks, Fix You, Viva la Vida, Radioactive, Believer and A Sky Full of Stars, played by a string ensemble among candles, for about an hour with doors opening 45 minutes early. Tickets cost from 15.50 to 31.50 euros depending on the seat, and seats are allocated on arrival by ticket type. It is an early-December evening of familiar pop in an unusual setting, which makes it simple to go alone: you know the songs, the lights are low and the room is quiet. Under-16s must be accompanied by an adult. «CANDLELIGHT Bilbao: Coldplay VS. Imagine Dragons» Starts 19:00, ends about 20:00. Source: Kulturklik, Basque Government culture agenda (CC BY).

On Saturday 5 December two bands, 48280 and Zilibito Records, play a concert at the Kafe Antzokia, a music venue and bar in Bilbao on Calle San Vicente. The Kulturklik listing gives little detail about the music beyond the names of the bands and the venue's own agenda as its source, so it is worth listening to both acts online first if you want to know what to expect. Tickets are sold in two tiers, from 10 euros, and we use the lower price. The language is Basque. The listing gives no end time, so we assume the show finishes around 23:30. It starts at 21:30. A club concert at a venue with its own bar is an easy night out for someone going alone, since the music gives everyone something to share. «48280 + Zilibito Records» Starts 21:30, ends about 23:30.

How it works
Not nationally. 6 December 2026 is a Sunday, and the 2026 BOE list (BOE-A-2025-21667) shows Monday 7 December as a holiday in ten communities: Andalucía, Aragón, Asturias, Cantabria, Castilla y León, Extremadura, Comunidad de Madrid, Región de Murcia, La Rioja and Melilla. Elsewhere, including Cataluña, Valencia and the País Vasco, check your regional and local calendar.
Yes. The Inmaculada Concepción falls on Tuesday 8 December 2026 and the BOE lists it as a non-replaceable national holiday in all 19 communities and cities.
Saturday 5 to Tuesday 8 December. Sunday 6 (Constitución) and Tuesday 8 (Inmaculada) bracket Monday 7, which is a holiday in ten communities and a bridge day of leave elsewhere.
Madrid’s Plaza Mayor market is listed by esMadrid for late November to 31 December 2026, free entry; the exact opening day is not published. The Fira de Santa Llúcia in Barcelona has no published 2026 dates yet (the 2025 edition ran 28 November to 23 December), so treat it as unconfirmed and check the organiser.
This page uses the open city calendars in our data as of 2026-10-25. They publish 2–6 weeks ahead, so more events appear through November and nothing here is invented. Where nothing is listed, use the always-on ideas.
