Measure the space between two dates
Use a duration to review how long something has taken or to set a realistic delivery window. The start and end dates remain visible beside the result so you can check exactly what was counted.
How the calculation works
Elapsed days exclude the start date. Business days count Monday through Friday; public holidays are not removed. Month arithmetic clamps to the last valid day when a destination month is shorter.
A useful next step
A calendar deadline and a working-day deadline answer different questions. Compare both before promising a delivery date, and allow for local public holidays separately.
