Online fullscreen clock user guide

How to use the fullscreen clock

Open Choose a face and search by name, or browse the previews to pick a clock.
Select Fullscreen to fill the display. Press Esc or use Exit fullscreen to return.
Open Clock settings to pick a time zone and switch between 12-hour and 24-hour time. Use Face settings to adjust size, colors or seconds where available. Your browser saves these choices on this device.

Choose a clock for your screen

Use large digits on a study desk, the analog face for a meeting room display, or the high-contrast flip clock when you need to read the time from across the room.

Studying, reading and focused work

Place a tablet or second screen beside your desk to check the current time while reading, writing or working. Large digits are easy to glance at; hide seconds and reduce the face size for less movement. Follow the clock against your own study schedule. This is a current-time display, with no Pomodoro timer, countdown or scheduled alerts.

Meeting rooms and presentations

Show the clock fullscreen on a meeting room display before a presentation or during discussion. The station face gives a clear view of hand positions; large digits also work for distant seats. Check size and contrast from the back of the room and select the meeting location’s time zone. If needed, enable the fullscreen screen-awake option and check that the browser has activated it.

Classrooms and study halls

Display the current time on a classroom screen so learners can plan exercises and independent study. Seven-segment or large-digit faces with 24-hour time distinguish morning from afternoon. Adjust the size for the viewing distance and hide seconds for a quieter display. Check the device time before class; arrange any end-of-activity reminders separately.

A home desk or bedside clock

Use a tablet on a shelf, desk or bedside table as a flip clock for everyday time checks. Try the pure-black theme at night and lower brightness on the device; choose light or dark colors to suit daytime lighting. Each face saves its own appearance settings. Keeping the screen lit still depends on the fullscreen screen-awake setting and browser support.

Remote teams and contacts abroad

Before calling a colleague or family member abroad, select their region’s time zone in Clock settings. A 24-hour dial helps place the time within the day; enable the date and time zone to check whether it is already the next day there. One selected zone appears at a time. Changing zones converts the device time; it does not correct the device clock.

Streaming backgrounds and screen recordings

Show a clock in a separate browser window when sharing your desktop or recording work. Choose a pixel or flip face, set the size, background and digit colors, then capture the window with your recording software. Preview the crop before starting. The clock shows the current time in the chosen zone; stream duration and elapsed recording time belong in your recording software.

Reusing an older tablet or spare display

Open the clock on an older tablet with a compatible browser or a spare computer display. A minimal round face suits a simple setup; adjust its size for portrait or landscape placement. Go online first and confirm offline resources are ready before reopening offline in a supported browser. Installation and fullscreen support vary by device, and screen-awake must be enabled separately.

Learning to read time and number codes

Compare digital and analog faces to practice reading time, or use the binary clock to explore place values of 8, 4, 2 and 1. Have the learner calculate each column at the current moment and check the digits underneath. The Berlin Clock also provides practice adding groups of five hours or five minutes. Open Clock stories for worked reading examples.
