The Date Difference Calculator shows the gap between two dates in days, weeks, months and years at once, updated live as you pick dates. A workday-only option counts weekdays (Monday-Friday) instead.
Use it for deadlines, project timelines, ages, anniversaries or countdowns. The today button snaps the end date to the current date. All calculations happen locally in your browser - no date is ever sent anywhere.
