How to use it
- Enter time now, target time and days away (0 = today).
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
Time left = days × 1440 + (target time - time now) in minutes, then split into days, hours and minutes.
Example
Inputs: Time now = 14:20, Target time = 18:00, Days away (0 = today) = 0. Result: Time left (H:MM): 3:40; Days: 0; Hours: 3.
Limits and caveats
- You type the current time yourself; it does not read your device clock.
- Daylight saving changes and time zone differences are not taken into account.
Questions about this tool
How do I count down to tomorrow morning?
Enter the target time and set days away to 1; from 22:00 to 06:00 tomorrow is 8 hours.
Why does it say the time has passed?
The target is earlier than now and days away is 0, so raise the days.
Are full days counted?
Yes, each day adds 24 hours, so 09:00 to 10:30 two days later is 49 hours 30 minutes.
