The National Flag of Argentina dates from 1812. It is a triband, composed of three equally wide horizontal bands colored light blue, white and light blue. In 1818, a yellow Sun of May was added to the center.

The full flag featuring the sun is called the Official Ceremonial Flag (Spanish: Bandera Official de Ceremonial). The flag without the sun is considered the Ornamental Flag (Spanish: Bandera de Ornato). While both versions are equally considered the national flag, the ornamental version must always be hoisted below the Official Ceremony Flag.
