pocket calendar 1400

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

This pocket calendar from about 1400 was intended to be used daily by farmers and therefore could be folded. In this form it had a size of 7,5 x 6,5 cm.

Besides the usual labour of the month and the respective sign of the zodiac it additionally shows a schematic representation of the average length of the day.
