About weeks and days
Multiply weeks by 7 to get days. 3 weeks is 21 days, 6 weeks is 42 days and 12 weeks is 84 days. A part week works the same way: 2.5 weeks is 17.5 days, which is 17 days and 12 hours.
Pregnancy, training plans, course lengths, sick notes and project sprints are counted in weeks, while booking systems and deadlines often need a number of days. Counting forward from a date? The date calculator adds the days for you.

- 40 wk (a full-term pregnancy) is 280 d
- 52 wk (a year in whole weeks) is 364 d
