The original thing you posted is not a calendar per se, but a computus, for calculating the dates of liturgical feasts based on what year it is, based on the motions of the sun and the moon, taking into account things like leap years and moveable and immovable feasts. 

You can then make your own calendar for the year that shows the feast days (or sometimes even lucky days for travel, bloodletting, or eating goose, etc) once you are done your calculations with such a tool.
