The historical, Aztec name for the huge basalt monolith, which is the Aztec calendar, is the Cuauhxicalli Eagle Bowl, but it is known to us as the “Aztec Calendar Stone“ or ”Sun Stone".

It was during the reign of the 6th Aztec monarch, during the complete decline of the empire of the ancient Maya Indians in 1479, that this stone was carved and dedicated to the main Aztec deity: The sun. The stone, the Aztec calendar, has both mythological and astronomical significance.

It weighs almost 25 tons, with a diameter of just under 12 feet (3,658 m) and 3 feet (0.914 m) thick. The stone was discovered on December 17th, 1790 in the 'Zocalo' (Main Square of Mexico City). Until 1885, the calendar was located in the Western Tower of Stolichny.

Later, it was deposited with the National Museum of Archaeology and History by order of the then President of the Republic, General Porfirio Diaz.
