# NETWORKDAYS.INTL

The NETWORKDAYS.INTL function calculates the number of workdays between two dates, considering specified weekend days and holidays. This function is useful for project management, tracking timelines, and managing work schedules efficiently.

## Syntax

=NETWORKDAYS.INTL(`start_date`, `end_date`, `[weekend]`, `[holidays]`)

When you need to determine the number of workdays between two dates in a project plan with unique weekend configurations and public holidays, turn to NETWORKDAYS.INTL in Excel. This function simplifies the task by offering flexibility in handling non-standard weekend days and specific holiday exclusions, streamlining work time calculations for enhanced productivity and project management efficiency.

## Examples

Suppose your project starts on May 1, 2023, and ends on May 15, 2023, with weekends set to Friday (6) and Saturday (7). You also want to exclude May 5 and May 10 as holidays. The NETWORKDAYS.INTL formula would be: =NETWORKDAYS.INTL("5/1/2023", "5/15/2023", '67', {"5/5/2023", "5/10/2023"}) This will return the total number of workdays between the specified dates excluding the defined holidays and weekends.

Suppose you want to calculate the workdays between January 1, 2023, and January 20, 2023, considering only Sunday (1) as a weekend day and excluding January 5, 2023, as a holiday. The NETWORKDAYS.INTL formula would be: =NETWORKDAYS.INTL("1/1/2023", "1/20/2023", 1, {"1/5/2023"}) This will provide the count of workdays within the specified range, accounting for the specified weekend day and holiday exclusion.

## Notes

Ensure that the start_date and end_date parameters are valid Excel date values or references to cells containing valid date values. The weekend parameter allows customization of weekend days by providing a number string that represents the days of the week (e.g., '67' for Friday and Saturday). The holidays parameter should be a range of valid dates or references to cells with date values to exclude them from workday calculation.
