Everyday time tools, in one place
oClock brings together the time tools people reach for most: a clock you can read from across the room, alarms, timers, a stopwatch, and ways to compare time zones and dates. Everything runs in your browser, so pages open quickly and there is nothing to install or sign up for.
Your settings and alarms are stored on your own device, not on an account. Time zones come from the same time zone database your device uses, so daylight saving changes are handled automatically for every city and date.
Browsers do have limits. Alarms and timers need the page to stay open, and a sleeping device can delay or stop them, so we explain what to expect on each tool rather than promising more than a web page can deliver.
Frequently asked questions
Is oClock free?
Yes. All the tools are free to use and no account is needed. The site may be supported by advertising.
Do I need to install anything?
No. Everything runs in your web browser on phones, tablets and computers.
Is the time accurate?
The clocks show your device's system time, which is normally kept in sync automatically by your operating system. If your device's clock is wrong, the time shown here will be too.
Will an alarm ring if I close the browser?
No. Web page alarms only ring while the page is open and the device is awake. For anything critical, use your phone's built-in alarm as well.
