Black screen with a clock — big digits on pure black

  • 01 Pure black background, digits sized to fill the screen
  • 02 12 or 24 hour, with date and seconds
  • 03 Six themes from black to daylight, plus paper

A black screen with the time on it, filling the whole display. Use it as a desk or bedside clock, on a spare monitor, a tablet on a stand or a TV across the room. Pick Black for pure black with soft white digits, or a warm theme for a dim room. Choose 12 or 24 hour time and show the date and seconds if you want them.

§ 01

A black screen that shows the time

The page is a plain black surface with one thing on it: the time. In fullscreen the digits are sized from the screen's width and height, so they take up most of the display whether it is a landscape monitor or a tablet held upright. Every digit is the same width, so the clock does not wobble as the numbers change.

§ 02

On an OLED or AMOLED screen, black pixels are switched off, so only the digits draw power and the room stays dark.

Black on OLED, dark on LCD

On an OLED or AMOLED screen, black pixels are switched off, so only the digits draw power and the room stays dark. An LCD still lights its backlight behind black, so the screen glows faintly in a dark room. Turn the device's own brightness down either way. If the screen will stay on for days, the night clock drifts the digits slowly to spare an OLED panel.

§ 03

Colour themes by temperature

Black uses soft white digits on pure black. Candle (about 1900K) and Warm (about 2700K) put amber digits on near-black, which is easy on the eyes in the evening. Neutral (about 4000K) and Daylight (about 6500K) move toward white and blue-white. Paper reverses it with dark ink on a warm cream page, for a bright room. The Kelvin figures are approximate matches to the lamp colour, not measurements of your display.

§ 04

Good uses for a black screen with a clock

A second monitor on a desk, a stage or classroom display, a kitchen tablet, a streaming setup where you want the time visible, or a TV during a party. Pair it with the timer page for a countdown beside it, or the night clock for a bedside screen in a dark room. For a more decorative display, try the flip clock.

Procedure

Three moves to peak output

  1. 01

    Start on black

    The clock opens on the Black theme: soft white digits on pure black. Switch to Candle or Warm for amber digits in a dim room, or Daylight and Paper for a bright one.

  2. 02

    Set the format

    The clock starts in your device's usual format. Use 12h or 24h to change it, and tick or untick Seconds and Date.

  3. 03

    Go fullscreen

    Press Fullscreen (or F, or double-click the clock) to hide the browser and leave only the time on black. On a TV, open the page in its browser or cast a laptop tab.

Inquiries

Questions worth asking

Q.01 How do I get a black screen with the time on it?
Open this page, leave the colour on Black and press Fullscreen. The screen turns pure black with the current time in the middle. Keep screen on stops the device from sleeping while the page is open.
Q.02 Can I show only hours and minutes?
Yes. Untick Seconds and the digits get larger, since there is less to fit across the screen.
Q.03 Does it follow my time zone?
It shows the local time and date of the device it is open on, including daylight saving changes. To show another city's time, change the time zone in the device settings.
Q.04 Can I use it on a smart TV?
Any TV with a web browser can open it, though some TV browsers lack fullscreen. Casting a laptop or phone tab (Chromecast, AirPlay or HDMI) gives the most reliable full picture.
Q.05 Where does the time come from?
From the clock of the device the page is open on, read again every second. Phones and computers set that clock from the network, so it should match your phone's lock screen. The page does not count seconds itself, so it cannot drift away from the real time.
Q.06 Will the screen stay on?
While Keep screen on is ticked, the page asks the browser to hold the display awake. Chrome, Edge and recent Safari support this. On a browser that does not, turn off auto-lock or the screen saver in the device settings. Untick the box if you want the device to sleep on its normal schedule.
Q.07 Does it work offline?
Once the page has loaded it needs no connection to keep showing the time. Nothing is streamed and nothing is sent anywhere while the clock runs.
