Event setup
Choose the saved event, target date, and countdown cues.
Event Countdown (Countdown to Date & Time)
Count down to an exact local date and time with saved events, fullscreen, optional sound, and quick adjustments.
Save and run dated events
Enter a label and local date-time, then save the event. New creates a separate entry, Duplicate copies the selected setup, and Delete removes it from this browser. Start controls the selected event's live display; quick hour adjustments move its target.
Create an event for 2026-08-01 at 09:00, then duplicate it and move the copy back two hours. The list holds both local targets. Reset restores the selected event's countdown state without deleting the saved entry.
Local date and storage rules
Events are stored in local browser storage and are not synced to an account or calendar. The target uses the device's local date and time-zone interpretation. A closed tab cannot deliver a durable alarm, and device sleep can delay the browser cue.
Counting down specifically to the next January 1? Use the New Year countdown for an automatic local-time countdown that rolls forward each year. For a simpler one-date setup without saved event management, use countdown to date. For a December 25 display, use the Christmas countdown. To count days between two dates, use the date duration calculator. For a plain days-remaining result without a live event timer, use the days until calculator. For a birthday-specific date entry, use the birthday countdown. For hours until a target date and time, use the hours until calculator. To add or subtract days, weeks, months, or years from a date, use the date calculator.
