in Roman antiquity, the kalendar wherein were expressed the several days of the year, with their feasts, games, and other ceremonies.

There were two sorts of fasti, the greater and lesser; the former being distinguished by the appellation fasti magistrates, and the latter by that of fasti calendares.

The greater fasti contained the feasts, with every thing relating to religion and the magistrates.

The lesser were again distinguished into the city and country fasti, each adapted to the people for whom they were designed. In all these fasti, the court-days, or those whereon causes might be heard and determined, were marked with the letter F; these days were called fasti, from fari, to speak or pronounce; and the other days, not marked with this letter, were called nefasti.
