Formula
The Days to Weeks Conversion Formula
Weeks = Days ÷ 7
To convert days into weeks, divide the number of days by 7 because there are 7 days in one week. This gives you the answer as decimal weeks.
If you also want the result as weeks + remaining days, take the whole number as weeks and convert the decimal part back into days.
Worked Examples
7 days
7 ÷ 7 = 1 week
14 days
14 ÷ 7 = 2 weeks
30 days
30 ÷ 7 = 4.29 weeks ≈ 4 weeks 2 days
60 days
60 ÷ 7 = 8.57 weeks = 8 weeks 4 days
90 days
90 ÷ 7 = 12.86 weeks = 12 weeks 6 days
Reverse Operation
Days = Weeks × 7
Working backward? Multiply weeks by 7 to get days. For example, 5 weeks × 7 = 35 days.
How to Convert
