Large time display
How do I show a clock with seconds in fullscreen?
Choose 12- or 24-hour time, keep seconds visible, and open the clock in fullscreen. The large digital clock uses your device's current system time, so correct the computer clock first if it appears inaccurate.
A fullscreen clock with seconds works well on a second monitor, projector, studio confidence screen, or shared office display. Hide the date or seconds when a calmer screen is more appropriate.
Classrooms and exams
Can I project a large clock during an exam?
Yes. Put the browser on the projector, select a high-contrast format, and enter fullscreen before the exam begins. Place the time where students can see it without turning around or reading tiny system controls.
Check your school or testing rules first: some exams require an approved wall clock or prohibit connected devices. A clock shows current time; use the classroom timer when students need to see time remaining.
Nothing leaves your screen.
