Weeks to Days Converter

The converter above is already set to weeks and days, so you only need to enter your number. The result updates as you type, and nothing is sent anywhere.

1. Type your value in the Value box, for example 6. Decimals and negative numbers are accepted.
2. Check that From shows weeks and To shows days. Both menus can be changed if you need a different pair.
3. Read the answer in the large result box. The note under it shows the exact factor used for one week.
4. Press Copy result to put the answer on your clipboard, or Swap units to convert in the opposite direction.
5. Look at In every unit on the right to see the same amount in all the other time units.

One week is exactly 7 days, so the formula is days = weeks x 7. Going the other way, one day is about 0.142857 weeks. A week is 7 days, which is 168 hours. A day in this converter is 24 hours, although calendar days around daylight saving changes can be 23 or 25 hours long.

Worked examples with the same factor:

• 6 weeks: 6 x 7 = 42 days
• 15 weeks: 15 x 7 = 105 days
• 60 weeks: 60 x 7 = 420 days

Multiply by 7: 6 weeks is 42 days.

To check the converter by hand, take 15 weeks and apply the rule once: the result should be 105 days. If you go back again with the reverse factor 0.142857 you land on 15 weeks, which confirms that the two directions agree. Rounding the factor to fewer digits for mental math gives a result that is close but not identical, so use the tool when the last digits matter.

These reference values come from the same factor the converter uses, so they match what you see above. Use the table for common amounts, and the converter for anything else.

Seconds, minutes, hours and days are linked by fixed factors of 60 and 24, so these conversions are exact. The complications come from calendars, not clocks: months have different lengths, years have leap days, and daylight saving time makes some days 23 or 25 hours long. For those cases a date calculator is the better tool, because it follows the real calendar instead of an average. Payroll software, shift planners and project tools often store durations as decimal hours, so people convert in both directions several times a week.

Use the table as a sanity check rather than a substitute for the converter. A half hour is 30 minutes, a quarter of an hour is 15, and a decimal hour of 0.1 is 6 minutes. When you read a timesheet, remember that decimal hours and clock time look similar but are not the same: 7.5 hours is 7 hours 30 minutes, not 7 hours 50 minutes.

Pregnancy, project plans, notice periods, courses and delivery estimates are quoted in weeks, while calendars count days.

Decimal hours are not hours and minutes: 1.5 hours is 1 hour 30 minutes, not 1 hour 50 minutes. When the result has a decimal, multiply the decimal part by 60 to get the minutes. Payroll systems usually want decimal hours, while schedules want hours and minutes.

The page keeps no history, so each visit starts again from the defaults, 6 weeks. Your numbers are processed by JavaScript in your own browser and are never sent to a server, which makes the converter safe for private figures such as medical, financial or work measurements.
