kalender – Create a calendar, in German

The pack­age de­fines a macro \Kal­en­der, which takes one ar­gu­ment, and gen­er­ates a cal­en­dar for the year the ar­gu­ment spec­i­fies. The cal­en­dar pro­vides a ta­ble of con­ver­sion of days to day of week, for the whole year plus De­cem­ber of the pre­vi­ous year and Jan­uary of the fol­low­ing year.
The macros use pack­ages calc and ifthen.
