America/New_York
The clock shows your own device's time, with seconds, in the time zone set on it. It keeps running without a connection once the page has loaded and looks great fullscreen on a classroom projector, a TV or a second monitor.
The time appears instantly, with seconds, in the time zone set on your computer or phone.
Switch between 12 hour (AM/PM) and 24 hour time and choose whether to show seconds. Your choice is saved in the browser.
Click Fullscreen to show only the clock, in huge digits on a dark background. Press Esc to leave.
The world clock strip shows the time in Los Angeles, Chicago, New York, London, Mumbai and Sydney, with each UTC offset.
In fullscreen the online clock fills the whole screen and can be read from the back of the room. Teachers use it to mark the end of tests and activities, speakers to keep track of time, and teams to keep the time visible on an office TV. The dark background avoids glare in dim rooms.
Because the time comes from your own device, the clock keeps running even if the internet drops after the page has loaded.
The clock shows your device's system time. Computers and phones sync their time over the internet automatically, so the difference is usually well under a second. If the time is wrong, turn on "Set time automatically" in your system's date and time settings.
The time zone under the date is your device's, for example America/New_York (UTC−05:00 in winter, UTC−04:00 during daylight saving time).
The large clock shows the current time in your device's time zone, updated every second. The world clock strip shows the time in major cities.
Click the Fullscreen button below the clock. To leave, press Esc or click the button again.
