Definition

The week is a unit of time equal to exactly 7 days (604,800 seconds). There is no standard SI symbol for the week. The seven-day week has ancient origins, with the earliest evidence from Mesopotamia. It became nearly universal through religious traditions (Jewish Sabbath cycle, Christian week, Islamic week) and was formally adopted by ISO 8601 for international date standards.

The week is not part of the SI system and has no decimal relationship to months or years, but it is universally used for scheduling and planning.
