Free Online Time Tools
World clock, countdown timer, alarm, stopwatch, Pomodoro, and HIIT. Open a tool and use it; nothing to install, and no account to create.
World Clock
Compare local times across cities. Add zones, drag cards to reorder them, and keep the layout in this browser.
Timer
Countdown in hours, minutes, and seconds. Pause, resume, and get a sound when time is up.
Alarm
Multiple labeled alarms with sound and notifications. Stored locally; the tab needs to stay open to ring.
Stopwatch
Elapsed time with lap splits and centisecond precision. Fullscreen when you need a larger display.
Pomodoro Timer
Work and break intervals with a todo list and session stats. Defaults follow the classic 25-minute focus block.
HIIT Timer
Custom work and rest rounds with a prep countdown. Useful for Tabata-style and circuit workouts.
How the clocks and timers work
Every display starts from your device clock. The world clock converts that instant into each city's IANA time zone, including daylight saving rules for zones that observe them. Timers, alarms, and the stopwatch count from the same clock and keep running state in this browser's local storage.
That means layouts and alarms stay on the machine you set them on. Clearing site data removes them. Alarms only ring while the tab is open, because the browser cannot schedule background sounds the way a phone OS can.
Popular city times
Each city page shows a live clock plus the IANA zone, standard offset, and daylight saving details when they apply. More cities sit on the world clock hub.
About ClockMinder
ClockMinder is a small suite of browser time tools built by Jeff Beem, an independent developer. The goal is simple pages that load quickly and do one job well: show the time somewhere else, count down, ring an alarm, or track intervals.
There is no account system and no app store package. Tools share the same Material-style UI so moving between the world clock and a timer feels familiar. For how the tools are built, see About.
