What Is the Online Clock?
The online clock shows the current time in hours, minutes, and seconds, straight from a browser tab. You can choose from three display formats: digital, analog, and flip.
By default, the clock with seconds shows the current time in your location. Use our world clock to see the time in different countries and time zones around the world.
How Do I Use the Online Clock?
- Click Digital Clock, Analog Clock, or Flip Clock to change the clock appearance.
- Click the full-screen symbol in the top right corner to switch to full-screen display (desktop only). Hit Esc to exit.
You can also use our online alarm clock to set an alarm and our online stopwatch and online timer to track how long something takes.
