How Many Days Until? Countdown Calculator

Instantly count how many days are left until your target date. Get the days, weeks, months, and weekday remaining to an exam, birthday, anniversary, or deadline. For past dates, see how many days have elapsed.

YYYY/MM/DD

Result

Enter a target date and a reference date.

How it works

  • Enter a target date and a reference date to count the days between them. The reference date is automatically set to today when you open the page, so you only need to pick a target date to see the days remaining.
  • The remaining days are also shown converted into weeks and months. Months are an approximation (1 month is treated as about 30.4 days), so they may differ slightly from exact calendar months.
  • Both the reference and target dates can be changed freely. You can combine past and future dates to measure the gap between any two days.
  • If the target date is before the reference date, the tool shows the number of days that have elapsed since then. This is handy for counting days since an anniversary or how many days have passed since an event.
  • When the target and reference dates are the same, the result shows "Today," which is useful for confirming the day has arrived.
  • Share the result to X with one tap. Great for keeping a countdown to an exam, birthday, event, or deadline.
