Countdown pages for launches, deadlines, and shared events
Set one target title, date, time, and interpretation mode, then keep that countdown page as the source of truth. This tool supports share URLs, iframe embeds, local or UTC interpretation, and analog + digital display. Background tabs may slow visual updates, so leave the countdown on the active screen when precision matters.
Good fits
- Publish a deadline or launch countdown with one sharable configuration.
- Switch between local and UTC interpretation before embedding the widget.
- Reuse recent targets for recurring events or meetings.
What to double-check
- The target timezone and whether the date/time should be local or UTC.
- Screen wake behavior if the countdown must remain visible in a room.
- Whether the embed or share URL should include the event title.
FAQ
Will the countdown drift in the background?
Display updates can throttle in background tabs, but remaining time is calculated from Date.now() so it stays accurate.
Does the share URL include the running state?
No. The URL shares settings only; the progress state is not included.
Which timezone is used for the target event?
The countdown uses the event timezone or interpretation mode you choose. If you enter a local-only date/time, confirm that timezone before sharing the link.
Can I reuse the same event setup later?
Yes. Save or share the settings URL to reopen the same title, date, time, and display options.
