Calculate the elapsed duration between two date-only values as days, hours, minutes, and seconds, plus inclusive business-day count. Reversed dates are accepted.
Quick Presets
Methodology and approach
The absolute elapsed milliseconds are decomposed into days, hours, minutes, and seconds. Business days are counted inclusively across the UTC calendar dates.
Enter dates in the format shown by this tool. Date-only calculations use calendar dates; date-time fields use local time unless a timezone selector is provided. Timestamp outputs identify their units.
