Days Until Calculator
Countdown to any future date
Counting down to a deadline, holiday, vacation or big day? Enter the target date to see how many days, weeks and months away it is.
Plan around the countdown
Enter any future date and we count from today. Pick a date in the past and it tells you how long ago it was instead. Great for deadlines, weddings, exams and launch dates.
Turn the countdown into a plan
Knowing you have, say, 90 days until an event makes it easy to work backward: break the time into weeks, assign milestones, and see whether your schedule is realistic. The weeks and months figures help with longer horizons like saving for a trip — pair it with the savings goal calculator to turn days into a weekly target.
Business days vs. calendar days
This tool counts calendar days, including weekends and holidays. If a deadline is quoted in "business days," expect it to land later than the raw countdown suggests, since a 10-business-day window spans two weekends — roughly 14 calendar days. For shipping and processing estimates, that gap matters.
