Add Days to a Date

Start from any date, choose how many days, weeks, months or years to add, and get the exact future date in return. This is the tool you reach for when a contract says net 30, a warranty runs 24 months, a recipe needs to ferment for 10 days, or you simply want to know what date falls a certain number of days from now. It shows the resulting date clearly along with the day of the week, so you can tell at a glance whether it lands on a weekend. Month and year additions respect calendar lengths, so adding a month to the 31st rolls correctly. Pick your starting point, enter the amounts, and the answer appears at once, computed entirely in your browser.

How to use Add Days to Date

  2. Enter the amount to add and select the unit of days, weeks, months or years.
  3. Read the resulting date and its weekday.

Frequently asked questions

Can I add weeks, months or years, not just days?

Yes. You choose the unit, and adding weeks multiplies by seven while adding months or years lands on the same day number in the later month or year.

What happens if the result month has no matching day?

Adding a month to January 31 rolls into the nearest valid date because the target month has fewer days, so calendar limits are respected.

Does the result show the weekday?

Yes. The resulting date includes the day of the week it falls on.
