Days Until Calculator - Countdown to Any Date
Calculate how many days remain until a birthday, holiday, deadline, trip, or any date with a live countdown and optional weekday-only counting.
DAYS UNTIL CALCULATOR
Choose any target date to see a live countdown in days, hours, minutes, and seconds. The same calculator can show how long ago a past date occurred.
Use it for birthdays, holidays, weddings, trips, launches, exams, project deadlines, or any event that begins on a known date.
Choose a target date and the countdown updates every second in days, hours, minutes, and seconds. The date is kept in this browser, so the same countdown is still running when you come back, and a date in the past reports elapsed time instead of remaining time.
The target is a calendar date without a time, so it begins at local midnight and a same-day target can report zero days while hours still remain. The count follows your device clock and time zone; changing either mid-countdown changes the figure.
Frequently Asked Questions
- Does the days-until count include weekends?
- The standard countdown includes every calendar day. Turn on Business Days Only to count Monday through Friday while excluding Saturdays and Sundays.
- Is it accurate for leap years?
- Yes. The target is handled as a real calendar date, so February 29 and different month lengths are included automatically.
- When does the countdown reach zero?
- It reaches zero at midnight at the beginning of the selected date in your device's local time zone. A partial day is shown as hours, minutes, and seconds rather than rounded up to another full day.
- Are public holidays excluded from business days?
- No. Business Days Only excludes weekends but cannot infer country-specific holidays, leave, or workplace closures.
- Is my countdown saved or uploaded?
- The selected date, optional event name, and weekday preference are stored in your browser's local storage so the countdown can be restored on this device. They are not uploaded by the calculator.
