Every time tool
you'll ever need

The Pomodoro Technique (developed by Francesco Cirillo, late 1980s) involves 25-minute focused work intervals followed by 5-minute breaks. After 4 intervals, take a 15–30 minute long break. Cognitive science research supports the core principle: regular breaks help the brain consolidate information and sustain attention. Millions of people report measurable productivity gains within the first week of consistent use. Our Pomodoro Clock is fully customisable so you can tune the intervals to your own work style.

Our stopwatch uses the browser's performance.now() API which provides sub-millisecond resolution. The display shows to hundredths of a second (10ms). This is accurate enough for sports timing, cooking, productivity tracking, and most real-world uses. For certified athletic competition timing, dedicated hardware is the standard.

Yes. All timers on ToolsDeck store the start timestamp (not a tick counter) so they remain accurate even when your tab is in the background, the browser throttles JavaScript, or your computer briefly sleeps. When you return to the tab, the correct remaining time is shown and the alarm fires if time has elapsed.

Use the Meeting Planner. Add each team member's city and the tool generates a 24-hour overlap chart highlighting hours that fall within business hours (9am–6pm) for everyone simultaneously. Teams spanning more than 10–12 time zones may need to rotate meeting times to share the inconvenience fairly.

All tools on ToolsDeck are completely free with no account or login required. Your preferences and history are saved locally in your browser using localStorage — nothing is ever sent to a server. There are no ads, no tracking, and no data collection of any kind.

Open the Date Calculator, set today as the start date and your target as the end date, and you'll instantly see the exact count in days, weeks, months and years. Great for countdowns to holidays, birthdays, deadlines, anniversaries, and any event you're looking forward to.
