Questions and answers

Does the clock stay accurate when I switch tabs?

Yes. The clock reads your device system time whenever it updates. If the browser pauses while hidden or locked, the display refreshes from the system clock when it resumes.

Can I hide the seconds or use 12-hour format?

Yes. Use the Seconds toggle to show or hide seconds, and the 12h / 24h buttons to switch formats. Your choices are saved in the browser and remembered next time.

How do I use the clock as a big desk display?

Click the fullscreen button or press F on your keyboard. The digits scale to fill the screen — ideal for a second monitor, a classroom display, or presenting in a meeting.
