What is a week?
A week is exactly 7 days, or 168 hours. Unlike months and years, the week is not tied to any astronomical cycle — it is a human convention with ancient roots that has become the backbone of work schedules, sprints, pay cycles, and pregnancy tracking.
Weeks convert exactly to seconds, minutes, hours, and days. Conversions to months and years use averages, since a calendar year contains about 52.18 weeks rather than a whole number.

Real-world examples
Pregnancy is typically 40 weeks, which is about 9.2 months. That is why the common "9 months" description is slightly off — doctors track pregnancy in weeks for precision.
A year has about 52.18 weeks. Reading one book a week is about 52 books a year — a popular challenge that adds up to 521 books over a decade.
Agile software teams plan in one- or two-week sprints, then roll weekly progress up into monthly and quarterly roadmaps, which requires converting between weeks and months.

About 52.18 weeks (365.25 days ÷ 7), which is why 52 weeks does not divide a year perfectly.
How many weeks are in a month?
