Weeks to Days Converter

Convert weeks to days with our free weeks to days converter — or flip it and turn days back into weeks. One week always has exactly 7 days, so the maths is simple, but it is easy to slip when you are counting a project deadline, a course length, a notice period, or the weeks of a pregnancy. This tool does it in seconds, with no sign-up and no download. It also accepts half weeks and other fractions, like 2.5 weeks, and it shows the answer in hours and minutes as well.

How to use this converter

1. Type the number of weeks in the Amount box. Fractions are fine — for example, type 2.5 for two and a half weeks.
2. Check that From says Weeks and To says Days. To go the other way, press the Swap units button so From says Days.
3. The result updates as you type. The big number is the answer, and the line below it shows the same period in hours and minutes.
4. If your period includes whole weeks plus a few spare days, use the Weeks plus extra days boxes to add them together in one total.

Common values

One row of this table is used far more than any other in daily life: 40 weeks = 280 days. That is the standard length used to count a full-term pregnancy, which is why due dates are often spoken of in weeks but the total is really 280 days. The 52-week row is also handy: 52 weeks = 364 days, which is one day short of a normal 365-day year, and two days short in a leap year.

How it works

A week is a fixed block of seven days. It does not stretch or shrink with the calendar, the month, or the season, and it is the same length in every country. That makes weeks to days the simplest time conversion of all: there is one exact factor, 7, and it never changes. Months are the tricky ones by comparison, because a month can hold 28, 29, 30, or 31 days — but a week is always seven days.

To turn weeks into days, multiply by 7. To turn days back into weeks, divide by 7. When the division does not come out even, the answer has a fraction. For example, 100 days ÷ 7 = about 14.29 weeks, which you can also read as 14 full weeks and 2 extra days, because 14 × 7 = 98 and 100 − 98 = 2. The combined boxes in the tool handle exactly that kind of split period.

Fractions of a week work the same way. Half a week is 0.5 × 7 = 3.5 days, so 2.5 weeks is 17.5 days. Half a day is just 12 hours, so an answer like 17.5 days is precise and complete — there is no hidden remainder to worry about. The converter also carries the result further into hours and minutes: multiply the days by 24 for hours, and the hours by 60 for minutes. So 12 weeks is 84 days, 2,016 hours, or 120,960 minutes.

People convert weeks into days for many everyday reasons: counting down to a delivery date, working out how long a course really runs, checking a notice period written in weeks, or following a pregnancy week by week. The day count is often the number that matters, because calendars and deadlines are kept in days and dates.

Worked example

Sana is planning a study timetable. Her course runs for 12 weeks, and she wants to know how many days she has in total so she can divide the syllabus evenly.

Step 1: Write down the number of weeks — 12 weeks.
Step 2: Use the formula — days = weeks × 7.
Step 3: Multiply: 12 × 7 = 84.
Step 4: Read the result — 84 days, which is also 2,016 hours or 120,960 minutes.

The reverse direction works the same way. If Sana later counts 84 days on her calendar and wants the week count again, she divides: 84 ÷ 7 = 12 weeks exactly. Those are the same results this converter gives for 12 weeks and for 84 days.
