Returns the number of whole workdays between two dates using parameters to indicate which and how many days are weekend days. Weekend days and any days that are specified as holidays are not considered as workdays.
NETWORKDAYS.INTL(start_date, end_date, [weekend], [holidays])
The NETWORKDAYS.INTL function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Start_date and end_date Required. The dates for which the difference is to be computed. The start_date can be earlier than, the same as, or later than the end_date.
- Weekend Optional. Indicates the days of the week that are weekend days and are not included in the number of whole working days between start_date and end_date. Weekend is a weekend number or string that specifies when weekends occur.
Weekend number values indicate the following weekend days:
|1 or omitted
Weekend string values are seven characters long and each character in the string represents a day of the week, starting with Monday. 1 represents a non-workday and 0 represents a workday. Only the characters 1 and 0 are permitted in the string. Using 1111111 will always return 0.
For example, 0000011 would result in a weekend that is Saturday and Sunday.
- Holidays Optional. An optional set of one or more dates that are to be excluded from the working day calendar. holidays shall be a range of cells that contain the dates, or an array constant of the serial values that represent those dates. The ordering of dates or serial values in holidays can be arbitrary.
- If start_date is later than end_date, the return value will be negative, and the magnitude will be the number of whole workdays.
- If start_date is out of range for the current date base value, NETWORKDAYS.INTL returns the #NUM! error value.
- If end_date is out of range for the current date base value, NETWORKDAYS.INTL returns the #NUM! error value.
- If a weekend string is of invalid length or contains invalid characters, NETWORKDAYS.INTL returns the #VALUE! error value.
