The word "calendar" derives from the Latin word "calendarium", which referred to an account book or register. This term was used because the Roman calendar took its name from the practice of announcing the occurrence of certain days (Kalendae) at the beginning of each month.
The word "week" has roots in Old English and Old Norse. In Old English, "wice" or "wec" meant a seven-day period, while the Old Norse "vika" referred to a week or a group of seven. These roots likely trace back to the Proto-Germanic word "wikō", which denoted "a change" or "a shift" since a week represents the completion of a cycle.
The combination "calendar week" thus signifies a week as measured by the calendar, aligning with the seven-day division widely used worldwide.
