How the conversion works

There are 7 days in a week, so to convert days to weeks you divide by 7. So 7 days is 1 week, 14 days is 2 weeks, and 21 days is 3. The number shrinks because a week is the larger unit, and unlike the month and year conversions, this one is exact, because a week is always exactly 7 days with no variation to average over.

Why weeks are a natural unit

Weeks are how people often think about stretches of time that run longer than a few days but shorter than a couple of months. Plans, schedules, and routines tend to be built around the week, so seeing a day count as weeks puts it in a frame that is easy to act on. A 21 day plan reads naturally as 3 weeks, and even when the days do not divide evenly, the decimal tells you where you stand, so 10 days is about a week and a half.

An example

Take 14 days. Divide by 7 and you have 2 weeks. A span of 21 days is 3 weeks, and 10 days is about 1.43 weeks, a little under a week and a half. The leftover days always show as the decimal part.
