Full-screen digital countdown timer
ReadyCount down to a duration or date in full screen. Customize digital LED themes, colors, digit transitions and animated backgrounds for free.
All tools are free to use. File size and processing limits may vary by tool.
Date mode uses the selected time zone and cannot be paused. Duration mode supports pause. New time settings apply when you press Start; colors update immediately. Background tabs may be throttled; remaining time is recalculated on return. Closing or reloading does not save the timer; this is not a system alarm.
Settings are hidden in full screen. Press Esc to exit, or double-tap the clock on a touch screen. Font appearance depends on fonts available on your device.

Appearance and colors
Digit size is capped to fit the screen. Turning motion off keeps a static background. Your device’s reduced-motion preference is respected initially. Design changes do not stop the timer and are not saved on reload.
Your device requests reduced motion; digit transitions are disabled.
The selected text and background have low contrast. Choose more readable colors.
Customize a full-screen digital countdown
Start a duration timer or count down to a date, time and time zone. The digital display uses seven-segment shapes with green, amber, blue, red LED and retro LCD themes. In the classic view you can adjust the font, weight, digit size and glow. Choose slide, flip, zoom or fade transitions and use Preview transition to check the effect before starting.
Use it for lessons, presentations and events
For a 25-minute focus session, choose duration mode; for an event opening, choose date mode. Set a title and enter full screen to hide controls and settings. Exit with Esc or a double tap on a touch screen. Pause is available only in duration mode. Resetting the appearance does not reset the timer. Matrix, stars and color-wave backgrounds can animate independently or remain still.
Browser limitations
This free tool is not a system alarm and sends no sound alerts or notifications. Closing or reloading the page resets the timer. Browsers may throttle updates in the background or while the screen is locked; remaining time is recalculated when you return. Digit animation is disabled when your device requests reduced motion. Date mode supports 2000–2100; choose the time zone where the event takes place.
How to start your countdown
Enter hours, minutes and seconds in duration mode, or use the 1, 5, 10 and 25-minute shortcuts. In date mode, choose a target date, time and time zone. Press Start. Open Appearance and colors to choose a theme, including LED and retro LCD digital displays. Set the digit transition and duration, then check it with Preview transition. Select Full screen for presentations and press Esc to exit. Duration timers can be paused and resumed.
Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
