A free online timer that counts down from the minutes you set, with an optional label. It keeps accurate time across a pause and a refresh.
The timer counts down from a number of minutes. It does not add up ticks. When you press Start it records the moment the timer is due, which is the clock reading at that instant plus the duration. What the display shows is one subtraction:
remaining = due moment - current time
The page reads the clock four times a second to refresh the display, and that reading is all the refresh does. No running total is kept, so a late or a missed refresh cannot make the timer drift.
Pause stores the time that is left rather than the moment the timer was due. Starting again sets a new due moment from the time that is left, so a pause of any length costs you nothing.
The display shows hours, minutes and seconds, and it rounds down. A 25 minute timer reads 00:24:59 a fraction of a second after it starts.
The timer, the stopwatch and the countdown timer share one workspace. A timer keeps running while you use the other two.
Set 25 minutes and press Start. Five minutes later the display reads 00:20:00. Press Pause and the timer holds 00:20:00, whether you come back after one minute or after one hour.
Press Start again and a new due moment is set 20 minutes ahead of that instant. The timer ends 20 minutes after you resumed it, not 25.
Set 90 minutes and switch to another tab. A browser slows a background tab down, and may refresh it once a second or less often. The timer loses none of that, because it works out what is left from the clock. Come back after 70 minutes and the display reads 00:20:00.
Yes. The timer holds the moment it is due, and every refresh subtracts the current time from that moment. A background tab is refreshed less often, so the number on screen changes less often, but it is correct each time it is worked out. The same holds for a phone with the screen off.
Yes, one tone, once. When the remaining time reaches zero the page plays a single 880 hertz note for one and a half seconds. The tone is not repeated, and there is no choice of sound. There is no desktop notification and no vibration.
A browser or an operating system can suspend a background tab, and a suspended page cannot play anything. The page says so above the timer. The display is always right when you come back. The sound is not promised.
A reload keeps the timer. What is stored is the moment it is due, so the page subtracts the current time from that moment and shows the time that has really passed. A timer whose moment has already gone reads 00:00:00 and Done.
Closing the tab ends it. The timer is held for the browser session and nothing is left behind, which is what Toolbox does with everything except your choice of theme. Nothing runs while the tab is closed either, so no tone can play.
From 1 minute to 1440 minutes, which is 24 hours. For anything longer, use the Countdown Timer, which accepts a date instead of a duration.
Yes. The application is stored in the browser after your first visit, so the timer opens and runs offline.
No. The duration, the label and the state of the timer stay in your browser. There is no account.
A browser gives a page two kinds of clock. One only counts forward and never jumps. The other reports the date and time, and can be set. This timer uses the second one, so it agrees with the clock on your screen. If the device clock is corrected while a timer runs, by hand or by a time server, the timer follows the correction.
The display counts hours and has no field for days, so a timer set to its longest duration reads 24:00:00 rather than one day.
For a duration in one unit stated in another, use the Time Unit Converter.
