Calculator for the remaining time to a deadline. Enter hours and minutes in 24 hours format of a regular deadline, for example knocking-off time at work. The time until the next occurrence will be displayed. If you press Start, you can bookmark this page and the next time you visit it, the remaining time to the next deadline will be shown.

As current time, the computer time will be used. The remaining time always refers to a date in the future, a day change will be ignored. If it is now e.g. 21:00 and the next deadline will be at 16:00, there are 19 hours remaining time.

This clock works like a reverse stopwatch, or rather like a countdown. First, the difference between the deadline time and the current time is calculated. This is then counted down by the second until the time reaches 0:00:00. Then the countdown begins again, i.e., at 23:59. There is no alarm when the time is up. Generally, you have to prepare for the appointment a certain amount of time in advance anyway, get there, and so on. Therefore, you rarely wait until it expires before taking action. Finally, appointments aren't always on time.

If you have to travel to an appointment, especially if the journey is long, you should work with a buffer. So you start so that, if all goes well, you will arrive at the appointment place early. Because there is no guarantee that everything will go well. You could get stuck in a traffic jam, have a breakdown, public transport could be delayed, or other unforeseen events could occur. How much time buffer is appropriate cannot be said in general terms; it also depends on how important it is to be there on time. This calculator can of course also work with a time buffer if, for example, the appointment is at 15:00 and you set 14:30 as the target time.
