Andalucía Day is a prominent holiday celebrated in Spain, specifically in the autonomous community of Andalucía. The Day is commemorated every 28th day of February and has been declared a public holiday since 1980. The holiday signifies the commemoration of a referendum held in 1980 that gave the entire region of Andalucia the power to become an autonomous community of its own within Spain.

During Andalucía Day, a flurry of events takes place which includes hoisting of the Andalusian flag, singing of the Andalusian anthem, and various cultural and educative events related to the history, culture, and traditions of Andalucía. Besides, local schools in the region have 'breakfast Andaluz', the traditional breakfast typically consisting of bread with olive oil. Many authorities also choose this day to give away their gold medals, the highest honor of the Autonomous Community.

The holiday is highly significant in the region as it reflects the historical moment that Andalucia became an autonomous community. It blends a mixture of political speeches, memories of the past, and celebrations for present achievements. The Day ensures that the pride, culture, and identity of the Andalucía region are preserved thereby cementing their unique status within the country of Spain.
