The Seven Days of the Week – Booklet

The German word Woche, or ‘week’ in English, has the same root as weichen, which means ‘to yield’ (when used in the sense of ‘making way’); or it may refer to Wechsel, which means ‘change’, as in the alternation of the days of the week (as one day changes into the next) and/or the rotation of the weeks as they follow the changing phases of the moon. Four weeks, namely, four lunar phases (the waxing moon, full moon, waning moon and new moon) form a lunar cycle, or one month.
