About TimeScreen
TimeScreen turns any browser tab into a large, readable online clock. It is built for people who need time visible at a glance while studying, teaching, presenting, training, or running meetings.
Use it as a full screen clock, a time screen display, a study clock, a beautiful desk clock, or a second-monitor clock that stays out of the way until you need it.
The clock can show digital, flip, LED, comic, analog, or simple default styles. Seconds, date, 12/24-hour format, timezone, display scale, theme, and shareable setup links are all available from the same clock surface.
Settings apply immediately and stay in your browser. A copied link includes only the clock options you choose, so the same setup can be opened again on another screen.
The time comes from your device system clock. If the device time is wrong, TimeScreen will show the same wrong time, so check the device time before precise classes, exams, or meetings.
Best Uses for a Full Screen Clock
Study and focus sessions: keep time visible without unlocking a phone or switching apps.
Classrooms and workshops: make the time readable from the back of the room or on a projector.
Meetings and events: place a simple time display on a shared screen so everyone sees the same clock.
Desk and second-monitor setups: keep a quiet online clock beside your main work without extra software.
Aesthetic displays: choose a clean digital, flip, LED, comic, or analog look that matches the room or stream.
How TimeScreen Works
Open the clock
The clock starts immediately, and the page title is kept visually hidden so the first screen stays focused on time.
Choose the setup
Pick a clock style, timezone, 12/24-hour format, seconds, date, and display size from the controls.
Use full screen
Expand the clock for a projector, classroom screen, desk display, TV, or second monitor.
Share or return
Copy a configured URL or rely on browser storage so your preferred setup is ready next time.
TimeScreen uses your device system time and does not claim network time calibration.
Changes apply immediately, save locally, and can be encoded into a shareable URL.
