To convert weeks to days, use a simple rule: 1 week = 7 days.
This week-to-day conversion works every time because weeks always have 7 days, even though months can have 28, 30, or 31 days.
A standard week has 7 days. This stays the same for calendars, schedules, and most planning needs.
Multiply the number of weeks by 7.
Example: 6 weeks × 7 = 42 days.
Days = Weeks × 7.
This works for whole weeks and partial weeks.
2 weeks equals 14 days (2 × 7).
3 weeks equals 21 days (3 × 7).
4 weeks equals 28 days (4 × 7).
5 weeks equals 35 days (5 × 7).
6 weeks equals 42 days (6 × 7).
8 weeks equals 56 days (8 × 7).
10 weeks equals 70 days (10 × 7).
12 weeks equals 84 days (12 × 7).
52 weeks equals 364 days (52 × 7). A common year has 365 days, so it’s 1 day longer than 52 weeks. Leap years have 366 days.
Multiply the fraction by 7.
Example: 1.5 weeks × 7 = 10.5 days.
Yes. Weeks and days can be shown with decimals when you need more detail.
Example: 2.25 weeks = 2.25 × 7 = 15.75 days.
A calendar week is always 7 days. A workweek can mean fewer workdays, like 5 days.
If you mean calendar days, use weeks × 7.
If you mean workdays, use weeks × workdays per week.
Not always. 4 weeks is 28 days. Most months have 30 or 31 days. February has 28 days, or 29 in leap years.
52 weeks is 364 days. Most years have 365 days, so there’s 1 extra day. Leap years add one more day, so they have 2 extra days beyond 52 weeks.
Add them together. 1 week is 7 days, plus 3 days equals 10 days.
2.5 weeks equals 17.5 days (2.5 × 7).
Pregnancy weeks are counted in 7-day weeks. To convert pregnancy weeks to days, multiply the weeks by 7, then add any extra days.
Example: 12 weeks and 3 days equals (12 × 7) + 3 = 87 days.
No. The conversion is fixed: 1 week = 7 days. The only time confusion comes up is when someone means workdays instead of calendar days.
