Date and Time - NETWORKDAYS Function
Description
The NETWORKDAYS function returns the number of whole working days between start_date and end_date. Working days exclude weekends and any dates identified in holidays.
Syntax
NETWORKDAYS (start_date, end_date, [holidays])
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Start_date | A date that represents the start date. | Required |
| End_date | A date that represents the end date. | Required |
| Holidays | An optional range of one or more dates to exclude from the working calendar, such as state and federal holidays and floating holidays. The list can be either a range of cells that contains the dates or an array constant of the serial numbers that represent the dates. |
Optional |
Notes
Microsoft Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2012 is serial number 40909 because it is 40,909 days after January 1, 1900
If any argument is not a valid date, NETWORKDAYS returns the #VALUE! error value
