WorksheetFunction.WorkDay Method (Excel)

Published: July 16, 2012

Returns a number that represents a date that is the indicated number of working days before or after a date (the starting date). Working days exclude weekends and any dates identified as holidays. Use WORKDAY to exclude weekends or holidays when you calculate invoice due dates, expected delivery times, or the number of days of work performed.

expression A variable that represents a WorksheetFunction object.

Parameters

Name

Required/Optional

Data Type

Description

Arg1

Required

Variant

Start_date - a date that represents the start date.

Arg2

Required

Variant

Days - the number of nonweekend and nonholiday days before or after start_date. A positive value for days yields a future date; a negative value yields a past date.

Arg3

Optional

Variant

Holidays - an optional list 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 contain the dates or an array constant of the serial numbers that represent the dates.

Return Value

Double

Important note Important

Dates should be entered by using the DATE function, or as results of other formulas or functions. For example, use DATE(2008,5,23) for the 23rd day of May, 2008. Problems can occur if dates are entered as text .

  • 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, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900. Microsoft Excel for the Macintosh uses a different date system as its default.

    Note Note

    Visual Basic for Applications (VBA) calculates serial dates differently than Excel. In VBA, serial number 1 is December 31, 1899, rather than January 1, 1900.

  • If any argument is not a valid date, WORKDAY returns the #VALUE! error value.

  • If start_date plus days yields an invalid date, WORKDAY returns the #NUM! error value.

  • If days is not an integer, it is truncated.
