Timers & Stopwatch
About this Tool
Your all-in-one timekeeping tool. Switch between a simple countdown Timer for focused tasks and a precise Stopwatch with lap tracking for measuring events. Whether you're in the kitchen, at the gym, or at your desk, this tool has you covered.
The tool uses your browser's `setInterval` function to create a 'tick' every few milliseconds. For the timer, it counts down from your set time. For the stopwatch, it counts up. Laps are recorded by capturing the current time of the stopwatch.
- Select either 'Timer' or 'Stopwatch' mode.
- For the Timer: set the hours, minutes, and seconds, then click 'Start'.
- For the Stopwatch: click 'Start' to begin, 'Stop' to pause, 'Lap' to record a split time, and 'Reset' to clear.
- Timing a 25-minute study session.
- Tracking your lap times during a run.
- Setting a reminder for something in the oven.
- Countdown Timer: Easy to set and includes a desktop notification when time is up.
- Precise Stopwatch: Measures time with millisecond accuracy.
- Lap Recording: Track split times without stopping the main timer.
- Clean Interface: A simple and focused design that's easy to use.
Digital timekeeping relies on the browser's internal clock. A timer decrements a set duration, while a stopwatch accumulates elapsed time from zero. Lap functionality simply records a snapshot of the elapsed time at a specific moment.
Will the timer work if I switch tabs?
Modern browsers may slow down timers in background tabs to save power. For best results, keep the tab open.
Is there a sound notification?
Yes, a simple chime will play when the countdown timer finishes.
Can I run multiple timers at once?
This version supports one timer or stopwatch at a time. You can open the tool in another tab to run a second one.
