What is the Date and Time Calculator?

Scheduling appointments, setting deadlines and planning the day all come down to the same question: what will the date or time be after a certain amount of time has passed? This calculator answers it in one step, with no manual counting.

It adds or subtracts minutes, hours, days, weeks, months or years from the current date and time and shows the result as a weekday, a date and, for minutes and hours, a time.

How to use it

  1. Type a number in the Number field.
  2. Choose a unit from the list, such as “Days from today” or “Hours ago from now”.
  3. Press Calculate. The answer appears at the top of the page.

Common questions

Which time zone does the calculator use?

Your device's. Results are based on the clock and time zone set on your phone or computer, and the zone in use is shown under the answer.

Why does the same calculation give a different answer tomorrow?

Every result is relative to the current moment. “5 days from today” moves forward by one day each day, so the answer is always up to date.

How are months and years added?

By calendar. If the target month is shorter than the starting one, the result moves to the last day of that month, so 31 January plus one month is 28 February (29 in a leap year).

Are the numbers I enter sent anywhere?

No. The calculation runs in your browser on your device.
