About this clock
This online clock shows the current time in your device's time zone, updated every second. Use the fullscreen mode to turn any screen into a wall clock, and toggle between 12-hour and 24-hour formats. It renders your system clock directly, so it is always in step with your device — including automatic daylight saving changes. Need a specific city?

Where a fullscreen web clock shines
- Classrooms and exams — project the time where everyone can see it; the seconds hand keeps timed tests honest.
- Kitchens and gyms — an old tablet or laptop becomes a glanceable wall clock, no app needed.
- Meetings and talks — keep a room aware of the time without a phone in hand. For a speaker countdown, see the stage timer.
- Studios and workshops — a silent, accurate time reference away from your main screen.
Frequently asked questions
How accurate is it?
It displays your device's system time tick by tick — the same time your operating system keeps synchronized with internet time servers. If your device clock is right, this clock is right.
Can I use it as a wall clock?
Yes — fullscreen mode strips everything but the time, ideal for a spare screen, projector or kiosk display.
