How to Calculate Working Days Between Two Dates in Excel

To calculate the number of business days between two dates, you use the NETWORKDAYS function. This function automatically excludes Saturdays and Sundays, allowing you to focus on actual production time. It is the most efficient way to track project timelines, employee shifts, or financial delivery deadlines without manual counting.

For advanced use, the function accepts an optional third argument called 'holidays'. By highlighting a range of cells containing your specific company or regional holidays, Excel will exclude those dates as well, giving you a precise count of active working days between your start and end dates.
