The Day of Andalusia (Día de Andalucía), also known as Andalusia Day, marks the anniversary of a referendum held on February 28, 1980. A large majority of voters supported this referendum for Andalucía to become an autonomous community in Spain. A public holiday is held to remember this event in the autonomous community Andalucía (also spelled as Andalusia), Spain, on February 28 each year.
Andalucía's flag is widely displayed on the Day of Andalucía. It consists of three equal horizontal bars. The top and lower bars are dark green and the middle bar is white. Andalucía's coat of arms is at the center of the flag. Andalucía's coat of arms consists of an image of the mythical Greek hero Heracles between two columns. The columns represent the Pillars of Heracles. These are the rocks on either side of the Straits of Gibraltar.
