What is week?
A week is a unit of time equal to 7 days. It is the standard cycle for work schedules, recurring events, sports seasons, and planning in most cultures worldwide.
Notes: Time unit
Real-world uses
Weeks structure work schedules, school timetables, pregnancy tracking (40 weeks), and agile software development sprints. Pay periods are often weekly or biweekly, and epidemiologists report disease incidence in weekly intervals.
History
The seven-day week has ancient origins, adopted by the Babylonians and later by the Romans, who named days after celestial bodies. It became entrenched in Western culture through the Jewish Sabbath tradition and was formalized in the Roman calendar.
Common mistakes
Assuming a month is exactly 4 weeks—most months are 4 weeks plus 2 or 3 days. Also, different cultures start the week on different days (Sunday in the US, Monday in ISO 8601 and most of Europe).

Did you know?
Earth's rotation is gradually slowing due to tidal friction with the Moon. To keep atomic time aligned with solar time, "leap seconds" have been inserted 27 times since 1972 — though they are scheduled to be abolished by 2035.
