NETWORKDAYS function

PRO BASIC

The NETWORKDAYS function in Jspreadsheet Formulas Pro calculates the total number of workdays between two specified dates. This function considers weekends (Saturday and Sunday by default) and optionally, any listed holidays, which are not counted. By using this function, you can easily determine the number of workdays in a given period, which is particularly useful for project planning or tracking attendance.

Documentation

Returns the number of whole workdays between start_date and end_date using parameters to indicate which and how many days are weekend days.

Syntax

NETWORKDAYS(start_date, end_date, [holidays])

Parameter	Description
`start_date`	The start date of the period.
`end_date`	The end date of the period.
`holidays`	Optional. A range of one or more dates to exclude from the working calendar, such as state and federal holidays and floating holidays.

Behavior

The NETWORKDAYS function is used to calculate the number of whole working days between two dates. It automatically excludes weekends (Saturday and Sunday) and optionally, a list of specified holidays.

Empty cells: If either start date or end date is left empty, the NETWORKDAYS function will return a #VALUE! error.
Text: If the start date or end date is entered as text that cannot be translated into a date, the function will return a #VALUE! error.
Booleans: The NETWORKDAYS function does not support boolean values. Boolean values are treated as numbers. Therefore, TRUE is regarded as 1 and FALSE as 0
Errors: If any of the provided arguments contain errors, the NETWORKDAYS function will propagate that error.
Date range: The start date should be less than or equal to the end date. If this rule is not followed, the NETWORKDAYS function will return a negative number.

Common Errors

Error	Description
`#VALUE!`	This error occurs when the start date or end date is not recognized as a valid date. This can happen when the cell is empty, contains text that cannot be translated into a date, or contains boolean values.
`#NUM!`	This error occurs when the start date or end date is out of Jspreadsheet's valid date range or is not a recognized date format.
`#REF!`	This error occurs when the list of holidays refers to a cell that is not valid.

Best practices

Always ensure that the start date and end date are valid dates, and the start date is less than or equal to the end date.

When specifying a list of holidays, make sure all the dates are valid and are in date format.

Use the NETWORKDAYS.INTL function if you want to customize which days of the week are considered weekends.

Remember that NETWORKDAYS function excludes the weekends and holidays in the calculation. If you want to include them, you may have to use other date functions.

Usage

A few examples using the NETWORKDAYS function.

NETWORKDAYS("2023-01-01","2023-03-15") returns the number of whole workdays between Jan 1, 2023 and Mar 15, 2023 excluding weekends  
NETWORKDAYS("4/1/2023","4/30/2023",B1:B10) returns the number of whole workdays in April 2023 excluding weekends and holidays listed in range B1:B10  
NETWORKDAYS(A2,B2,["12/25/2023","1/1/2024"]) returns the number of whole workdays between the dates in cells A2 and B2, excluding weekends and holidays Dec 25, 2023 and Jan 1, 2024
