Days Until (Countdown) Calculator
See how many days remain until an upcoming date, or how many have passed since a past one.
Your countdown, instantly
Enter any date and this tool counts the whole days between today and that date. Future dates show the days remaining; past dates show how long ago they were. It is handy for holidays, birthdays, deadlines, launches, and events.
How the count works
The calculation compares calendar days (ignoring the time of day), so a date tomorrow reads as 1 day, and today reads as 0. Time zones can shift midnight boundaries; the count uses your device’s local date.
Frequently asked questions
Does it count today?
