About these tools
How long until⦠and how old exactly?
The countdown timer counts down to any date and time β product launches, birthdays, deadlines, vacations. Set the target once and watch days, hours, minutes, and seconds tick away. It's the simplest possible motivator: a visible number makes an abstract future date feel real, which is why teams put launch countdowns on office screens.
The age calculator finds an exact age in years, months, and days from any birth date β more precise than subtracting years, and it handles leap years and month lengths correctly. Useful for forms, milestones ("how many days old is the baby?"), anniversaries, and trivia.
Focus and measure
The Pomodoro timer runs the classic focus technique: 25 minutes of work, 5 minutes of break, with a session counter and a beep when each interval ends. The method works because the timer externalizes discipline β you're not relying on willpower to stay on task, just on the agreement that you'll work until the beep. After four sessions, take the longer break; your brain will thank you.
The stopwatch measures elapsed time to the millisecond with lap times β workouts, cooking, experiments, speedruns, or settling once and for all how long the microwave actually takes. Laps let you compare segments without stopping the clock.
The time zone converter answers the other eternal question: what time is it over there? Enter a date and time in one zone, convert to another, and daylight saving is handled automatically β no more mental UTC arithmetic before scheduling the call.
All five tools run in your browser with no account and no tracking. The countdown and Pomodoro keep running in the tab while you work in others.
Questions, answered
Does the countdown timer work if I close the tab?
The countdown computes from your target date each time the page loads, so reopening the page shows the correct remaining time. For a live ticking display, keep the tab open.
What is the Pomodoro Technique?
A focus method: work for 25 minutes, break for 5, and after four work sessions take a longer 15β30 minute break. The timer here follows that rhythm with a session counter and an audible beep.
How accurate is the stopwatch?
It measures to the millisecond using your browser's high-resolution timer β plenty precise for workouts, cooking, and experiments, though not a substitute for certified timing equipment.
