    I have a batch file that runs every day, which is fine, but there are certain parts of it that I want to run on a certain date. If it's not that certain date, then skip over that part of the batch file.

    I know how to use the "goto" command to redirect the batch file to the proper section, but how do I check the date in a batch file?

    Thanks in advance!

    %date% will give you the current date in a batch file. You can use an if statement to check it.
    The format will be the same as your regional settings, so it depends on your settings and what exactly you want to check, say skip a part every saturday/sunday, or skip on the 5th, 10th, 15th, etc.
    Couple of ways to break down the data, either use set (see set /?) to extract a substring (can be iffy if your system doesn't always use 2 digits for month/day), or a FOR statment with the proper delimiters
    For example on my system %date% is Fri 03/28/2008, so:
    Set _day=%date:~0,3% would set _day to Fri
    set _date=%date:~7,2% would set _date to 28
    If your settings don't display a leading zero, then this last one won't work consistantly because the position in the string changes. Better to use FOR in that case.

    This FOR statement will parse the %date% value using a space and / as delimiters, and puts all 4 values into separate variables:
    for /f "tokens=1-4 delims=/ " %%I in ("%date%") do Set _Day=%%I & Set _Month=%%J & Set _Date=%%K & Set _Year=%%L
    If you just need one value (say the date), change the tokens=1-4 to tokens=3 and just use set _date=%%I.
    If your settings don't display the day of the week, remove the space between the / and " after delims=

    See for /? for info on those options.

    Thanks Jerry - I was actually able to do this with just a line:

    if "%date%!" == "Tue 04/01/2008!" goto PRANK

    (guess what I'm doing to my boss on Tues... LOL)

    First Name:
    Hi there,
    I could not help but notice your post.

    I have some vbs code (requires WSCRIPT to be allowed) that sets a number op environment variables which you can use to create folders, logs, whatever, look into these maybe they can be of use.

    Create a directory C:\BAT (or anything you wish and wherever you wish)
    You will need to create the following files:

    Alls codes to be found hereunder:


    dtUur = Right("0" & hour(time),2)
    dtMin = Right("0" & Minute(time) ,2)
    dtTijd = dtUur & ":" & dtMin

    Years = year(date)
    Months = Right("0" & datepart("m",date),2)
    Days = Right("0" & datepart("d",date),2)

    WeekNr = wNumber(year(date), month(date), day(date))
    If Int(WeekNr / 2) = WeekNr /2 Then WeekOdd = "NO" Else WeekOdd = "YES"

    Public Const cHideWindow = 0, cNormalWindow = 1
    Set WSHShell = Wscript.CreateObject("WScript.Shell")
    Set FSO = Wscript.CreateObject("Scripting.FileSystemObject")
    Set EnvVar = wshShell.Environment("Process")

    tQ1 = Kwartaal(date)

    tQ2 = Kwartaal( date + 1)

    tempFile= EnvVar("TEMP") & "\EnvVars.bat"
    Set File2Write = fso.createtextfile(tempFile,1)
    File2Write.writeline("Set Hour=" & DtUur )
    File2Write.writeline("Set Time=" & dtUur & ":" & dtMin)
    File2Write.writeline("set Year=" & Years)
    File2Write.writeline("set Month=" & Months)
    File2Write.writeline("set MonthDay=" & Months & Days)
    File2Write.writeline("set YYYYMMDD=" & Years & Months & Days )
    File2Write.writeline("set MMDDJJJJ=" & Months & "-" & Days & "-" & Years)
    File2Write.writeline("set YearMonth=" & Years & Months)
    File2Write.writeline("set Today=" & Days & "-" & Months & "-" & Years )
    File2Write.writeline("set WeekNr="& WeekNr)
    File2Write.writeline("set WeekOdd="& WeekOdd)
    File2Write.writeline("set Quarter="& tQ2 - tQ1)
    File2Write.writeline("set StartDate=" & right("0" & day(date-6),2) & "-" & right("0" & month(date-6),2) & "-" & year(date-6))
    File2Write.writeline("set StopDate=" & right("0" & day(date-1),2) & "-" & right("0" & month(date-1),2) & "-" & year(date-1))

    tempFile= EnvVar("TEMP") & "\OK.txt"
    Set File2Write = fso.createtextfile(tempFile,1)


    function WNumber(Y, M, D)
    dim N, Tdy, Thu, SoY, YNo, WNo, DoW
    N = 2
    Tdy = DateSerial(Y, M, D) '' Date, args
    Thu = ((Tdy+3+N) \ 7) * 7 - N '' Nearest Thu
    YNo = Year(Thu)
    SoY = DateSerial(YNo, 1, 1) '' Date, YYYY-01-01
    WNo = ((Thu - SoY) \ 7) + 1
    WNumber = Right(100+WNo,2) '' always return two digits
    end function

    Function Kwartaal(tDate)
    mnd = Month(tDate)
    If mnd = 1 Or mnd = 2 Or mnd = 3 Then
    Kw = 1
    ElseIf mnd = 4 Or mnd = 5 Or mnd = 6 Then
    Kw =2
    ElseIf mnd = 7 Or mnd = 8 Or mnd = 9 Then
    Kw = 3
    Kw = 4
    End If
    Kwartaal = Kw
    End Function

    @echo off
    rem This file calls SetVars.vbs, make sure the path exists in my case C:\Bat
    rem First it deletes the files if they exist
    rem Setvars.vbs creates two (2) files in the user's TEMP foldeer
    rem OK.txt
    rem EnvVars,bat
    rem this batchfile loops until the %TEMP%\OK.txt is created
    rem Then it calls EnvVars.bat to have the varaiables active for use
    rem To view the values run EnvShow.bat

    if exist %TEMP%\Ok.txt del %TEMP%\Ok.txt
    if exist %TEMP%\EnvVars.Bat del %TEMP%\EnvVars.bat
    Wscript C:\Bat\SetVars.vbs
    if not exist %TEMP%\OK.txt goto waitloop
    CALL %TEMP%\EnvVars.Bat

    To see the results Wacht the C:\BAT path I use and make it your path


    @Echo off
    call C:\Bat\GetEm.Bat
    call %temp%\EnvVars.bat
    echo %date% %time%
    Echo HOUR=%hour%
    Echo TIME=%Time%
    Echo YEAR=%year%
    Echo MONTH=%month%
    Echo MONTHDAY=%monthday%
    Echo YYYYMMDD=%yyyymmdd%
    Echo YEARMONTH=%yearmonth%
    Echo MMDDJJJJ=%MMDDJJJJ% format is mm dd yyyy
    Echo TODAY=%today% format is dd mm yyyy
    Echo QUARTER=%quarter% (if value = 1 then tomorrow is a new Quarter)

    Echo StartDate=%startdate%
    Echo StopDate=%stopdate%
