How many days until my birthday?
Birthday countdown for your date and time zone. Count calendar days or add an event time. Save the event or share its fixed date.
How to use
Enter the date for Birthday. Add the event time and location time zone if the hour matters, such as an exam start or flight departure. The page never guesses a personal date. Saved personal events keep the date you chose; changing language preserves your custom name.
Date calculation
New events can follow the device time zone. Uncheck that option to fix a zone, and search by city or IANA name. Shared links pin the zone at creation. A running countdown keeps its target when the device zone changes. Daylight saving follows the selected zone.
Sharing
Choose a countdown type, name, target and time zone, then create a link. Each recipient uses the same fixed target. A later visit does not restart it. Editing requires a new link; there is no host control or live group pause.

Sound and browser limits
Browser alerts need an open tab and device support. Sleep, muted audio or a closed browser can prevent an alert. Calendar events have no alarm. This tool uses your device clock; clock errors can cause differences between recipients.
Storage preferences
Allow saving to keep presets, events, language, region and appearance in this browser. Without permission, presets and events last for this page visit. This tab keeps active timers, those preferences and drafts for language changes. Clearing browser data removes saved data. No account or cross-device backup.
