Constitution Day

Spain’s Constitution Day, or Día de la Constitución, is observed annually on 6 December to commemorate the nationwide referendum held on 6 December 1978. In that vote, Spanish citizens approved the Constitution that established the foundations of the country’s current parliamentary democracy, recognizing fundamental rights and freedoms and defining the distribution of powers among the state, the autonomous communities, and local institutions. The text was approved by the Spanish Parliament, sanctioned by King Juan Carlos I, and formally promulgated on 27 December 1978.

The holiday is closely associated with Spain’s democratic transition after the death of General Francisco Franco in 1975. The Constitution represented a negotiated political agreement among diverse groups and replaced the institutional framework of the dictatorship with a constitutional monarchy and a pluralist democratic system. Constitution Day became a nationwide public holiday in the early 1980s and remains an important occasion for reflecting on civic participation, democratic institutions, regional diversity, and the rights and duties of Spanish citizens. In 2026, 6 December falls on a Sunday; any substitute weekday holiday depends on the official national and regional labor calendars, while 8 December is separately observed as the Feast of the Immaculate Conception.

Celebrations on Constitution Day are generally civic and institutional rather than religious. The Congress of Deputies and the Senate commonly organize commemorative events, official speeches, guided visits, exhibitions, and educational activities about the Constitution and Spain’s democratic history. Public buildings may display the Spanish flag, schools often discuss constitutional values and citizenship, and political and community organizations issue statements marking the anniversary. Ceremonies frequently emphasize democratic coexistence, equality before the law, national unity alongside territorial diversity, and respect for civil liberties.

For many people, the day is part of the December holiday period linking Constitution Day with the Immaculate Conception on 8 December, creating a popular long weekend or puente when the calendar permits. Families and friends may travel, visit cultural sites, attend local events, or share seasonal meals rather than follow a single nationwide custom or special dish. Typical foods vary by region and may include winter stews, roasted meats, seafood, cured products, and Christmas sweets such as turrón and polvorones. Common greetings include Feliz Día de la Constitución and Feliz Día de la Constitución Española, although informal conversations often focus simply on enjoying the holiday weekend.
