Formula
The Weeks to Days Conversion Formula
Days = Weeks × 7
To convert weeks into days, multiply the number of weeks by 7 because one standard week contains 7 days.
This gives you an exact day count for whole-week inputs. The calculator uses whole weeks so the result stays clean and easy to use in planning documents.
Worked Examples
1 week
1 × 7 = 7 days
2 weeks
2 × 7 = 14 days
4 weeks
4 × 7 = 28 days
6 weeks
6 × 7 = 42 days
12 weeks
12 × 7 = 84 days
Reverse Operation
Weeks = Days ÷ 7
Working backward? Divide days by 7 to get weeks. For example, 28 days ÷ 7 = 4 weeks. Or use the days to weeks converter directly.
