The word fastos comes from Latin roots, from the entry "fastus", and it derives from an Indo-European root. Fastos also known as fasto is a term used in Ancient Rome to describe the calendar or almanac where each of the possible dates of the numerous celebrations, games, events, memorable events and parties of that time were available. On the other hand, it could also be said that they were those days when the superior deities allowed us to do business and work; and those in which these activities were not allowed were known as "ne fastus" or "nefarious".
It was the great Roman poet named Ovid who, in the full maturity of his life, composed the poetic calendar called "Fastos", where he shows the many Roman festivals and the history related to each of them; this public figure a letter with each of the months of the year, of which until now only the first six months of the year are preserved. In this work I try to illustrate the Roman calendar with the peculiarity of explaining the origin of the names of the months, as well as the origin of the festivals and those astronomical characteristics of each moment.
These writings are made up of six books, dedicated to the first six months of the year; Because for the year 8 that the first emperor of the Roman Empire, Caesar Augustus expelled Ovid for his work " Art of loving ", so that it would remain incomplete until June. All these writings begin with the explanation of each of the possible origins of the name of the month that is related.
The months were arranged as follows: in Book I about the month of January, related to the deity Janus; II February associated with the Term God; book III, March with the divinity Mars; the IV for April related to the divinity called Venus; the letter V for May associated with Las Musas and finally, the book VI, June related to Juno and Juventus
