Time tools
Fast, no-login time tools — a countdown timer, stopwatch, Pomodoro timer, and world clock to time tasks, focus, and track time zones, all in your browser.
- Alarm Clock
An online alarm clock for any time you type, or one of eight common wake-ups: four sounds, a five-minute snooze, a fullscreen bedside face, and it survives a refresh.
- Countdown Timer
Countdown timer with quick presets and an alarm that keeps beeping until you stop it. Set anything up to 99:59:59 and the tab title tracks the time left.
- Countdown to Date
Countdown to any date. How many days until a birthday, a holiday or a deadline, counted down to the second.
- Pomodoro Timer
A pomodoro timer with a task list. Twenty-five minutes of focus, five off, a long break every fourth round, and every finished session counted against what you're working on.
- Stopwatch
An online stopwatch that counts in hundredths, records laps into a Lap/Split/Total table, exports them as CSV, and runs from the Space and L keys.
- Time Difference
A time duration calculator for the gap between two clock times. Enter start and end, take off an unpaid break, and read it as 8h 0m, 8.00 decimal hours, or 480 minutes.
- Week Number
The ISO 8601 week number for today or any date you pick, with the day of the year, the weeks left in it, and that week's Monday and Sunday.
- World Clock & Time Zone Converter
A world clock and time zone converter with a meeting planner that finds the hour everyone is at work, then copies the slot in each city's own local time.
These time tools handle the small time-keeping jobs that punctuate a working day — set a countdown timer for a meeting, a break, or something in the oven; time a task to the centisecond with a lap-recording stopwatch; run focused Pomodoro sessions; or check the time across the world. Each opens instantly, with no login and nothing to install, so you can start in a single click and leave the tab open all day.
They run entirely in your browser, which is what makes them reliable to keep pinned: the timer keeps counting and updates the tab title even when you switch away, an alarm sounds when it reaches zero, and you can bookmark a preset link to reopen the exact timer you use most. Bookmark the one you reach for and it is always a tab away.
