The Weeks to Days Conversion Formula
Days = Weeks × 7

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
12 weeks

52 weeks
52 × 7 = 364 days
Reverse Operation
