Time & Clock

Eleven tools here read, measure or convert time. Three are clocks you leave running: a full-screen online clock, a word clock that spells the current time out in English, and the world clock, which has a page for each of 244 countries and territories with the local time in its main cities. Three measure elapsed or remaining time — a stopwatch with lap times, a countdown to a date you pick, and a Pomodoro timer with adjustable work and break intervals — while the plain timer takes any duration and alerts you in the browser. The time zone converter maps a moment in one zone onto another and accounts for daylight saving; the time calculator adds and subtracts hours and minutes without spilling into decimal errors. Two more build embeddable widgets, a clock and a countdown, that you paste into your own page as an iframe. The clocks and timers read your device's own clock, so they keep working if your connection drops.
