ExampleFormulaResult

Include Holidays=WORKDAY(C7,D7,F7)12/7/2015

Syntax and Arguments:

The Syntax for the WORKDAY Formula is:

Function Arguments ( Inputs ):

start_date – The start date in Excel serial number format or entered as a date with quotations (“s) surround the date. Example: You can not enter 11/12/2015 directly into the cell. Instead you need to enter “11/12/2015” or you would need to use the corresponding serial number: 42320. Alternatively, you can reference a cell with the date 11/12/2015 entered. Excel automatically converts dates stored in cells into serial format (unless the date is entered as text).

days – The number of non-weekend and non-holiday days from the start date.

holidays – OPTIONAL. An array with a list of dates representing holidays that should be excluded from workdays.

Additional Notes

The result of the WORKDAY Function may appear as a serial number. Change the cell Number Formatting to Short Date to display the serial number as a date:
