# NETWORKDAYS

The NETWORKDAYS function is used to calculate the number of working days between two specified dates, excluding weekends and optionally, specified holidays. This function is handy for scheduling and project management tasks where you need to determine the number of business days.

## Syntax

=NETWORKDAYS(`Start_Date`, `End_Date`, `[Holidays]`)

When you're faced with the task of determining the number of working days between two dates, enter the NETWORKDAYS function in Excel. Particularly beneficial for individuals managing time-sensitive projects or planning schedules, this function provides a straightforward solution to exclude weekends and predefined holidays from the calculation of the duration between two dates. By utilizing NETWORKDAYS, you obtain a precise count of business days, enabling efficient scheduling and resource allocation in various scenarios. You can enhance the accuracy of the calculation by specifying holidays to be excluded, accommodating different regional or organizational holiday schedules. Whether you're coordinating project timelines or estimating delivery dates, NETWORKDAYS proves to be a reliable ally in your Excel toolkit.

## Examples

Suppose a project starts on August 1, 2022, and ends on August 31, 2022. You want to calculate the number of working days between these dates excluding weekends. The NETWORKDAYS formula would be: =NETWORKDAYS("8/1/2022", "8/31/2022")

If you want to exclude specific holidays, let's say September 5, 2022, and October 10, 2022, from the calculation, you can modify the formula as follows: =NETWORKDAYS("8/1/2022", "8/31/2022", {"9/5/2022", "10/10/2022"})

In the case where your organization has a list of holidays stored in cells A1:A5, you can refer to this range by inputting it as the `Holidays` argument: =NETWORKDAYS("8/1/2022", "8/31/2022", A1:A5)

## Notes

Ensure that the dates entered are in a valid Excel date format or references to cells containing valid date values. Weekend days (Saturday and Sunday) are automatically excluded from the calculation. Make sure to adjust the function parameters according to the specific requirements of your project or scheduling task.

## Questions

Can I use the NETWORKDAYS function to calculate the duration in hours or minutes?

No, the NETWORKDAYS function specifically calculates the number of working days between two dates, excluding weekends and optional holidays. To calculate the duration in hours or minutes, you would need to use other functions or formulas in Excel.

How does the NETWORKDAYS function handle weekends in different regions or countries?

The NETWORKDAYS function automatically considers Saturday and Sunday as weekends, which aligns with the typical workweek structure in many countries. However, the function does not account for custom weekend definitions specific to certain regions or organizations.

Is it possible to use the NETWORKDAYS function to exclude custom-defined non-working days other than weekends and holidays?

The NETWORKDAYS function does not provide direct support for excluding custom-defined non-working days beyond weekends and specified holidays. If you need to account for additional non-working days, you may need to explore more advanced solutions involving custom formulas or VBA programming.
