About Date Difference Calculator

The Date Difference Calculator measures the span between two dates. Pick a start date and an end date and the tool reports the gap in days, weeks, months, and years, plus a separate count of business days that excludes Saturdays and Sundays. The results refresh as soon as you adjust either date.

All of the math happens in your browser, so the dates you select are never uploaded. It is useful for tracking project timelines, counting working days before a deadline, or finding out how long ago an event took place.

Frequently asked questions

How are business days counted?
Business days include every day in the range except Saturdays and Sundays; public holidays are not removed.
Does the order of the dates matter?
No. The tool measures the gap regardless of which date you place first.
Is the end date included in the count?
The difference is measured between the two dates, so the span reflects the number of days from start to end.
