How to convert days into weeks and days
- Divide the days by 7 and keep the whole number. That is the number of full weeks.
- Multiply the weeks by 7 and subtract from the days. What is left is the extra days.
Example: 44 days ÷ 7 = 6.29, so there are 6 full weeks. 6 × 7 = 42, and 44 − 42 = 2. So 44 days is 6 weeks and 2 days.
