Conversion Formula
The formula used to convert days into weeks is simple: weeks = days ÷ 7. Since one week contains exactly 7 days, dividing the total days by 7 will give the equivalent weeks.
Why it works? Because weeks group days in sets of 7, so dividing the total days by 7 counts how many groups (weeks) fit inside the days.
Example calculation for 105 days:
- Start with 105 days
- Divide by 7 (days per week): 105 ÷ 7
- Result is 15 weeks
- So, 105 days equals 15 weeks
Conversion Example
- Example 1: 56 days
- Divide 56 by 7
- 56 ÷ 7 = 8 weeks

- 90 ÷ 7 ≈ 12.857 weeks
- So, 90 days is about 12.857 weeks
