These were festivals where religious officials employed by the State conducted public rites. Citizens were required to suspend business on such dates, but they were not required to attend religious ceremonies (many did so, however, as sacrificial meat was often given in such festivals). Because the ancient Romans did not observe a "weekend" as moderns do, these festivals would have constituted the days of rest for the populace.
