Abstract (en)
Calendar apparatus 10 comprises two scale members, namely a fixed main body 12 and a rotatable disc 20. Scales 28 to 42 are printed on the scale members to identify data relating to centuries, years, months, day names and day numbers. The method of the invention permits the calculation of the day names for a chosen month in the past or in the future to be performed by two movements of scale 20.
