Free Online Clock – World Clock, Stopwatch, Timer & Alarm
This free utility website brings the core features of the iPhone Clock app to any browser. Check the exact current time with seconds, view world times in major cities, run a precise stopwatch with lap times, set countdown timers, create alarms, browse a monthly calendar, and see local sunrise and sunset times. You can also hear the current time spoken aloud with one click. Everything runs locally in your browser — no account, no downloads, and no data sent to a server.
Why Use an Online Clock?
People search for an online clock for many practical reasons: checking the exact time with seconds during exams or recordings, coordinating meetings across time zones, timing workouts or cooking, or simply having a large, readable clock on a second monitor. Unlike a phone or computer clock that can be easy to miss, a full-screen or large digital display keeps the time visible at a glance. This tool is designed to be fast, accurate, and distraction-free while still offering the most useful features from a modern clock app.
World Clock & Time Zones
See live clocks for cities such as New York, London, Tokyo, Sydney, Dubai, Paris, Beijing, Los Angeles, Singapore, and more. Times update every second so you always know the current local time in each location. This is especially helpful for remote teams, freelancers working with international clients, travelers planning calls, or anyone who needs to convert time zones quickly without opening a separate converter. You can also save your own favorite cities so they appear every time you return to the page.
Stopwatch, Timer & Alarm
The stopwatch is ideal for workouts, study sessions, experiments, or any activity where you need precise elapsed time and lap splits. The countdown timer works well for cooking, Pomodoro focus sessions, presentations, or short breaks. Simple alarms can be set while the page remains open and can trigger browser notifications if you allow them. All of these tools continue to work offline after the first load, making the site useful even when your connection is unstable.
Calendar, Sunrise & Sunset
Browse the current month and navigate forward or backward to check dates quickly. Sunrise and sunset times are calculated from your approximate location so you can plan outdoor activities, photography, or daily routines. Day length is also shown for convenience. Location detection happens only in your browser; nothing is stored on a server.
Multi-language Support & Accessibility
The interface is available in English, Spanish, French, Arabic (with right-to-left layout), and Simplified Chinese. This makes the clock usable for a wider audience without needing separate sites or browser translation. The design prioritizes large, readable numbers, clear buttons, and a clean layout that works on both desktop and mobile screens.
Privacy and How It Works
This online clock is built with privacy in mind. Location is detected locally (with an optional IP-based fallback only when needed for city name and sunrise calculations). Favorites and alarms are saved in your browser’s local storage so they stay on your device. There is no user account, no tracking of the times you look up, and no requirement to install an app. The goal is a lightweight, reliable utility that does one job well.
Frequently Asked Questions
Is this online clock free?
Yes. The tool is completely free to use. No registration or payment is required.
How accurate is the time?
The displayed time comes from your device’s system clock, which modern operating systems keep synchronized using Network Time Protocol (NTP). This is the same source used by most computers and phones, so the seconds you see are as accurate as your device allows.
Does the stopwatch and timer work offline?
Yes. After the page has loaded once, the stopwatch, timer, and most other features continue to work even if you lose internet connectivity.
Can I use it on mobile?
Yes. The layout is responsive and works on phones and tablets. You can also add the page to your home screen for quick access.
Why do I need an online clock when my phone already has one?
Many people prefer a large, always-visible clock on a computer monitor, classroom display, or second screen. Others need world times, a clean stopwatch with laps, or sunrise data without switching apps. This page combines those features in one simple place.
Is my location data private?
Location is used only to show your local city name and to calculate sunrise/sunset. It is processed in the browser. Favorites and alarms never leave your device.
