How to use the Excel NETWORKDAYS.INTL function

Summary

The Excel NETWORKDAYS.INTL function calculates the number of working days between two dates. NETWORKDAYS.INTL excludes Saturday and Sunday by default, but provides a way to specify which days of the week are considered weekends. The function can optionally exclude a list of holidays supplied as dates.

Purpose

Get work days between two dates

Return value

A number representing days.

Syntax

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

Arguments

start_date - The start date.
end_date - The end date.
weekend - [optional] Setting for which days of the week should be considered weekends.
holidays - [optional] A reference to dates that should be considered non-work days.

Usage notes

NETWORKDAYS.INTL calculates work days between two dates. Work days exclude weekends (Saturday and Sunday by default) and can optionally exclude holidays. This function is more robust that the NETWORKDAYS function, because it allows you to control which days of the week are considered weekends. The weekend argument is set using the codes listed in the table below.

NETWORKDAYS.INTL can also optionally take into account holidays. For the holidays argument, supply a range that contains holiday dates. These are also treated as non-working days and will not be included in the result.

In the example shown, the following formulas are used:

D4=NETWORKDAYS.INTL(B4,C4)
D5=NETWORKDAYS.INTL(B5,C5,17)
D6=NETWORKDAYS.INTL(B6,C6,1,B9:B10)

Weekend number	Weekend days
1 (default)	Saturday, Sunday
2	Sunday, Monday
3	Monday, Tuesday
4	Tuesday, Wednesday
5	Wednesday, Thursday
6	Thursday, Friday
7	Friday, Saturday
11	Sunday only
12	Monday only
13	Tuesday only
14	Wednesday only
15	Thursday only
16	Friday only
17	Saturday only

Notes:

If start_date is greater than end_date, the the function returns a negative value.
If start_date or end_date are out of range, NETWORKDAYS.INTL returns the #NUM! error.
If weekend is invalid, NETWORKDAYS.INTL returns the #VALUE! error.
