Add or Subtract Weeks from a Date
Add or subtract weeks from any date to find the date X weeks later or earlier. Shows the weekday instantly.
Input
Result
Enter a start date and the number of weeks.
How it works
- Pick a start date, enter the number of weeks to add or subtract, and choose "before" or "after" to see the resulting date right away.
- Because the date shifts in whole weeks (multiples of 7 days), the result always lands on the same weekday as the start date — useful for planning recurring meetings or shifts.
- The total number of days shifted (weeks × 7) is shown too, so you can also check the result on a day basis.
- Enter a whole number of weeks that is 0 or greater. You can calculate up to about 100 years (5,220 weeks).
- Share your result directly using the "Share on X" button.
