Online Timer — Free Countdown Timer

What Is an Online Timer?

An online timer is a web-based tool that helps you measure and manage time directly from your browser. Unlike traditional stopwatches or kitchen timers, an online timer requires no downloads or installations. It runs entirely in your browser, making it accessible from any device — desktop, tablet, or phone. Whether you need a classroom timer for teaching, a 1 hour timer for cooking, or a simple stopwatch for workouts, our platform has you covered.

Countdown Timer

Our countdown timer is one of the most versatile tools available. You can set it for any duration by tapping the display and entering hours, minutes, and seconds. Need an online timer 10 minutes for a quick break? Tap, set, and start. Preparing for a presentation and need an online timer 5 minutes for your speaking slot? Done. Studying with the Pomodoro technique and want an online timer 30 minutes for deep focus? It takes just a few seconds to configure. The countdown includes a circular progress ring that visually shrinks as time elapses, giving you a clear sense of time remaining at a glance. You can also share your countdown with others via a unique link, making it perfect for remote teams or virtual classrooms.

Stopwatch

A stopwatch (also spelled stop watch) is essential for timing events, races, experiments, or any activity where you need precise elapsed time measurement. Our online stopwatch offers accuracy to 10 milliseconds and includes a lap recording feature. Whether you are a coach timing athletes, a scientist recording reaction times, or a fitness enthusiast tracking sets, this stopwatch delivers reliable performance. The lap feature lets you record split times without stopping the main timer, so you can analyze each segment of your activity in detail. It is the ideal stop watch for anyone who needs precision timing on demand.

Pomodoro Timer

The pomodoro timer implements the popular Pomodoro Technique, a time management method developed by Francesco Cirillo. Work in focused 25-minute intervals (called "pomodoros"), then take a short break. Our pomodoro timer is simple to use: just start the default 25-minute session and focus until the alarm sounds. It updates the page title with the remaining time so you can track progress even when the tab is in the background. This tool is ideal for students, writers, programmers, and anyone who struggles with distractions.

World Clock

Our world clock displays the current time across 16 major cities worldwide, including London, New York, Tokyo, Dubai, and Sydney. Each card shows the city flag, current time in 24-hour format, date, and UTC offset. The display refreshes every second so you always see the live time. You can also tap any city to enter fullscreen mode. Whether you are scheduling international meetings or keeping track of family in different time zones, this clock makes it easy.
