Tips & tricks
This clock reads the time straight from your device, so it is always correct and needs no setup. The large fixed-width digits are designed to be read at a glance from across a room.
It makes a great second-screen clock. Put an old phone or tablet on a stand, open this page in fullscreen, and you have a sharp digital wall clock. Because dark mode is automatic, it won't glare at night.

Frequently asked questions
Does the online clock show the correct time?
Yes. It reads the time directly from your device's clock, so it is as accurate as your phone or computer and needs no configuration.
