History of Argentina The history of Argentina is divided by historians into four main parts: the pre-Columbian time or early history (up to the sixteenth century), the colonial period (1530–1810), the period of nation-building (1810-1880), and the history of modern Argentina (from around 1880).
Trecena A trecena is a 13-day period used in pre-Columbian Mesoamerican calendars. The 260-day calendar (the "tonalpohualli") was divided into 20 trecenas. Trecena is derived from the Spanish chroniclers and translates to "a group of thirteen" in the same way that a dozen (or in Spanish "docena") relates to the number twelve. It is associated with the Aztecs, but is called different names in the calendars of the Maya, Zapotec, Mixtec, and others of the region.
