Date Calculator
Find the difference between two dates, or add or subtract days, weeks, months and years from a date. Working days are shown too
- Difference: we count full years first, then remaining months, then remaining days. Total days is simply the number of days between the two dates
- Working days: Monday to Friday. Holidays are not counted, only Saturdays and Sundays are excluded
- Add/subtract: years and months are applied first, then weeks and days. If the new month does not have that day (for example 31 Jan + 1 month), you get the last day of that month
- For a notice period or project deadline, turn on "Include end date" so both days are counted
- To see how many days are left from today, set the start date to today
Your dates are used only in your browser. Nothing is saved or sent anywhere.
