Online timers and clocks

Four tools cover the everyday ways of keeping time. Use the Timer for pasta, a plank or a timed quiz; the Stopwatch to measure a run or a speech, with lap times; the Alarm clock for a reminder at a set time; and the Pomodoro timer to alternate focus sessions with short breaks. For common lengths there are ready-made 5, 10, 15 and 30-minute timer pages that start with one click.

Choose by the question you need answered. "How long is left?" calls for the Timer, "How long did that take?" for the Stopwatch, "Remind me at 7:30" for the Alarm clock, and "Keep me on task" for the Pomodoro timer. Whichever you use, keep its tab open, because closing it stops the clock. The alarm clock also needs your device awake and not muted, and the Timer, Stopwatch and Alarm clock can keep the screen awake on browsers that support it.
