Count down to a future date. Enter the target date and the tool shows how many days are left, along with the gap in years, months, and days. It works for holidays, birthdays, exams, launches, and any deadline you are counting toward. If the date has already passed, the count is shown as negative.

How this is calculated

The days-remaining figure is the exact number of UTC calendar days from the reference date to the target date, so it is timezone-free and counts leap days. The year, month, and day breakdown uses the standard relativedelta convention over the same span.

How to use

  1. Enter the target date you are counting toward.
  2. Leave the from date on today or set another starting point.
  3. Read the days remaining and the full breakdown below.

Examples

  • Countdown: From 2026-07-08 until 2026-12-25 → 170 days
  • Already passed: A date earlier than today shows a negative count

FAQ

What if the target date is in the past?
The days-remaining count becomes negative to show the date has passed, and the breakdown still reports the size of the gap.
Is today counted?
The count is the difference between the two dates, so a target equal to the from date shows zero days remaining.
Are leap years handled?
Yes. The day count is a direct calendar-day difference, so any February 29 in the range is included.
