How Long Until 5 PM (or Any Time)?

Subtract the time now from 5:00 PM. In 24-hour time 5:00 PM is 17:00, so at 1:30 PM it's 17:00 − 13:30 = 3 hours 30 minutes. The countdown at the top of this page does that from your own clock and keeps it current to the second.

Find the hours and minutes left, then multiply the hours by 60 and add the minutes. 2 hours 15 minutes is 2 × 60 + 15 = 135 minutes. The calculator shows this as Total minutes, with total seconds next to it.

Then the next one is tomorrow, and the page counts to that and marks it Tomorrow. At 6:00 PM, the time until 9:00 AM is 15 hours. Right at the target time, the page shows that it's that time now for one minute before it moves on to tomorrow.

Yes. It reads the clock and time zone on the device you're using, and shows the zone it used under the answer. If your device clock is wrong, the countdown will be off by the same amount. To count to a time in another zone, convert that time to your own zone first.

The countdown is real elapsed time. On the night clocks change, that can be an hour more or less than the gap between the two clock readings. In the US, NIST explains that clocks jump from 2:00 AM to 3:00 AM on the second Sunday of March and go from 2:00 AM back to 1:00 AM on the first Sunday of November. So at 11:00 PM the night before the spring change, 7:00 AM is 7 hours away, not 8. The page adds a note when a change falls inside your countdown.

Yes. Press Start a timer for this. It opens the online timer with the time left already filled in, so press Start there right away and it will sound an alarm when it reaches zero. To ring at a set clock time instead, like 6:30 AM, use the alarm clock that rings at a clock time.

Not on this page. It's built for clock times today or tomorrow. For the hours and minutes between two dates and times, use the date mode of the time duration calculator.
