    Formula for adding days to a date excluding weekends and holidays?

    Ok I have done some searching on this forum and others but can't seem to find
    the answer i am looking for so hopefully somebody can help me. I am trying
    to setup a sheet that will produce production dates for me. My problem is
    that we do not work on the weekends or holidays. I have one formula that
    calculates the number of days a process takes to complete and I link that to
    the date the previous process ended. For example if the last process ended
    on a thursday and the next process takes 3 days I want the formula to skip
    over the saturday and sunday when it calculates what day the process will
    finish. I have tried to use the NETWORKDAYS function but I can't seem to get
    that to work. Any help is greatly appreciated as I seem to be fairly
    braindead today and cant figure it out myself. Thanks alot!!

    Use the WORKDAY function instead:

    A B C
    1 Task Duration Completed
    2 First Task 4 01/06/06
    3 Task 2 6 =WORKDAY(C2,B3,HOLIDAYS)

    Where "HOLIDAYS" is a named range of all of your holiday dates (see
    http://www.contextures.com/xlNames01.html for details on naming ranges)

    Jake, I have xl3000 and the Excel Help seems straight forward. Just put all your holidays in a range and include it in the formula:

    NETWORKDAYS
    Show All
    Hide All
    Returns the number of whole working days between start_date and end_date. Working days exclude weekends and any dates identified in holidays. Use NETWORKDAYS to calculate employee benefits that accrue based on the number of days worked during a specific term.

    NETWORKDAYS(start_date,end_date,holidays)

    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.

    Start_date is a date that represents the start date.

    End_date is a date that represents the end date.

    Holidays is 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 (array: Used to build single formulas that produce multiple results or that operate on a group of arguments that are arranged in rows and columns. An array range shares a common formula; an array constant is a group of constants used as an argument.) of the serial numbers that represent the dates.

    Date Description
    10/01/2008 Start date of project
    3/01/2009 End date of project
    11/26/2008 Holiday
    12/4/2008 Holiday
    1/21/2009 Holiday
    Formula Description (Result)
    =NETWORKDAYS(A2,A3) Number of workdays between the start and end date above (108)
    =NETWORKDAYS(A2,A3,A4) Number of workdays between the start and end date above, excluding the first holiday (107)
    =NETWORKDAYS(A2,A3,A4:A6) Number of workdays between the start and end date above, excluding every holiday above (105)
