About Date Calculator

Enter a start date and how much to add or take away. Years and months are applied first, then weeks and days; when the day does not exist in the target month it is moved to that month's last day (31 January + 1 month = 28 February, or 29 in a leap year).

Switch to business days to skip weekends - Saturday-Sunday as in the UAE, Friday-Saturday, or others. Public holidays are not skipped here; the Working Days Calculator can take a holiday list.

How to use it

  1. 1Pick the start date (today by default).
  2. 2Choose Add or Subtract and enter years, months, weeks and days.
  3. 3Or switch to business days and choose the weekend.
  4. 4Read the resulting date and weekday, and copy it.
