The calendar calculator module contains a set of levers and cams that create the rules through which the calendar module becomes a 'third order' perpetual calendar which keeps the calendar in step with the Earth's time. Basically it accounts for the quadrennial leap year, the one hundred year exception rule and the 400 year exception rule. Making it good for 400 years. Very few clocks have come equipped with such a calendar and when they do it is because it is a component within a perpetual Easter computus indicating the moveable feast of Easter, the Easter computus is the most complex complication in horology. Only a handful of clocks have ever been made with this function. But unlike these other calendars, ours also works in reverse. The reason for this feature is that the calendar acts as a temporal reference for the machine's celestial indicators when in demonstration mode in forward or reverse and it easily allows the machine's operator to reset the demonstration back to the present day after the demonstration is over.
