Custom time
This timer counts down from a selected duration to zero. Choose a preset when you need a quick countdown, or enter custom hours, minutes, and seconds for exact timing.
The timer can be paused and resumed without losing the remaining time. Reset returns the countdown to the currently selected preset or custom duration.
Preset timers are useful when you need a quick duration without entering numbers by hand. Short presets work well for breaks, small chores, quick reminders, and warmups. Longer presets are helpful for focused work sessions, study blocks, practice routines, cooking times, and exercise intervals.
Custom settings are better when the time needs to be exact. Enter the hours, minutes, and seconds you want, set the timer, then start the countdown.
A countdown gives a work session a clear boundary for focused work before a break.
Short timers help keep stretches, screen breaks, chores, and daily routines from drifting longer than intended.
A custom countdown helps when a recipe or chore needs a specific duration.
Timers work well for exercise intervals, rest windows, drills, and practice blocks.
Choose the timer when the duration is known before you start. A countdown is best for deadlines, reminders, focus blocks, cooking times, break limits, and routines where the end point matters.
Choose the stopwatch when the duration is the thing you want to measure. A stopwatch is best for tracking attempts, comparing laps, recording task length, timing an activity, or understanding how long a process really takes.
Yes. Use the custom hours, minutes, and seconds fields, then set the timer before starting the countdown. The selected custom duration becomes the timer's reset point.
A timer counts down from a set amount of time to zero. A stopwatch counts up from zero so you can measure how long something takes.
Yes. Start the stopwatch and use the lap control to save recent split times while the elapsed time continues.
The timer uses timestamps rather than simply counting browser ticks, so it corrects itself when the tab resumes or the browser throttles background updates.
Yes. The countdown plays a short browser-generated chime when it reaches zero. Your browser, device, or operating system volume settings can affect whether you hear it.
Yes. Both tools can be paused and resumed. Reset returns the timer to its selected duration and clears the stopwatch back to zero.
