    2:00 am answer10:00 am nowFri, Oct 16 (UTC)
    Same day: Fri, Oct 16, 10:00 am − 8 hours = Fri, Oct 16, 2:00 am

    Now is the moment the page opens, in your time zone; without JavaScript the page counts in UTC and says so.

    • Real elapsed time. A day is 24 hours: Friday 10:00 am + 1 day 14 hours = Sunday 12:00 am.
    • Clock changes. If the span crosses a daylight-saving change in your time zone, the answer is still elapsed time — the wall clock shows an hour more or less, and the page warns under the answer.

    FAQ

    How does the time calculator work?

    Enter the days, hours, and minutes to add or subtract and choose 'From Now' or 'Ago'. The calculator counts from the current date and time: in your time zone once the page loads, in UTC without JavaScript.

    Can I calculate a date in the past instead of the future?

    Yes. Switch the direction to 'Ago' to subtract the entered days, hours, and minutes from the current date and time instead of adding them.

    What time zone is the result calculated in?

    The answer is shown in your own time zone — the page reads it from your browser, and you can pick a different one under the answer. With JavaScript turned off the page prints the same moment in UTC and says so next to the answer.

    Can I combine days, hours, and minutes in one calculation?

    Yes. All three fields can be filled in at once — for example, 2 days, 5 hours, and 30 minutes — and the calculator adds (or subtracts) them together in a single step.
