This guide provides a practical overview of NETWORKDAYS. INTL Function, including its main features, benefits, limitations, and important considerations.

Description: The function returns the number of whole working days between two dates by using a parameter that determines the number of weekends and which day of the week.

Syntax: NETWORKDAYS. INTL (start_date, end_date, [weekend], [holidays])

Inside:

- start_date: Start date to calculate the number of working days, is a required parameter.

- end_date: The end date to calculate the number of working days, which is a required parameter.

- weekend: The method of calculating the number of weekends is not counted in the working day, including the values:

+ weekend = 1 or skip -> Weekends are Saturdays and Sundays.

+ weekend = 2 -> The weekend is Sunday, Monday.

+ weekend = 3 -> Weekends are Monday and Tuesday.

+ weekend = 4 -> Weekends are Tuesday and Wednesday.

+ weekend = 5 -> Weekends are Wednesdays and Thursdays.

+ weekend = 6 -> Weekends are Thursdays and Fridays.

+ weekend = 7 -> Weekends are Fridays and Saturdays.

+ weekend = 11 -> Sunday weekends.

+ weekend = 12 -> The weekend is Monday.

+ weekend = 17 -> Weekends are Saturdays.

- holidays: Holidays need to be excluded from the working day, these days are usually not on a fixed list, is an optional parameter.

Attention:

- If start_date > end_date -> The return value is negative and the magnitude of the value will be the number of complete working days.

- If the value of start_date or end_date is outside the current date range -> the function returns the #NUM! Error value

- If the weekend value is not valid -> the function returns the #VALUE! Error value

For example:

Calculate the number of whole working days to know the number of weekends not counted in working days.

In the cell to calculate enter the formula: = NETWORKDAYS. INTL (E7, F7, G7, H7).

- Press Enter -> return value is:

Here the total number of working days is 240 days except Saturday and Sunday not working and the total has 40 Sundays and 40 Saturdays.

- Similarly, there is an extra day off -> number of working days is:

- Copy the formula for the remaining values to get the result:

- Where start_date > end_date -> return value is less than 0 -> actual number of working days in the past.

Here the value is -270 -> past working days is 270 days.
