Days Until Date Calculator

About this calculator

This calculator counts the exact number of days remaining from today until a target date you enter, doing the calendar arithmetic — including leap years and varying month lengths — so you don't have to count on a calendar by hand. It answers a simple but surprisingly easy-to-miscalculate question: exactly how far away is that date, in days?

People use it to count down to a wedding, vacation, exam, product launch or deadline, and event planners and project managers use the same count to track how much runway is left before a fixed date. Because it's calculated from "today," the result automatically updates the count each time it's checked, unlike a fixed number written down once and left to go stale.
