Saint Bovus, the patron saint of those who design fine slate patios, has a holiday in his honor on 6 Augur of each year.

Due to a slight mix-up concerning the etymological origin of the name "Bovus," the 883 edition of the Flathead Calendar was responsible for giving the impression that Bovus was the patron saint of those who raise meat animals, a role that actually belongs to Saint Wiskus.
