One may have come across calendars of a radial arrangement so far, nevertheless, this Anaptár calendar, visualising the data of the Sun and the Moon in a novel fashion. The method of data presentation and visual depiction of the lunar cycle never seen before actually makes astronomic correlations apparent. The development of this system of representing lunar data was inspired by calendars of Très Riches Heures du duc de Berry, Giovanni Battista Agnese and Clipclop.
