Stopwatches, clocks and time calculators
Not every timing job is a countdown. These tools count up, ring at a wall-clock time, or do the arithmetic for you — all free, in the browser, with nothing to install.
Use the stopwatch when you don't know how long something will take, the alarm clock when the deadline is a time of day rather than a duration, and the calculators when you need a number instead of a beep.

Frequently asked questions
What's the difference between a stopwatch and a timer?
A stopwatch counts up from zero and you stop it yourself; a timer counts down from a duration you set and alerts you at zero. Use the stopwatch when the length is unknown.
Does the stopwatch keep laps?
Yes. Lap times are recorded while it runs and stay listed until you reset, so you can compare splits afterwards.
Is any of my data stored on a server?
No. Laps, history and stats live in your browser's local storage only, and nothing is uploaded.
