I like my solution... Grosely bad.... :)

You MUST have a delimiter between the fields...

#include <Date.au3>
_DateYesterday ("D/M/Y")

Func _DateYesterday ($string)
    $string = StringSplit ($string, "")
    $yesterday=StringSplit (_DateAdd('d',-1, _NowCalcDate()),"/")
    $output = ""
    If $string[1] = "D" Then
        $output &= $yesterday[3] & $string[2]
    ElseIf $string[1] = "M" Then
        $output &= $yesterday[2] & $string[2]
    ElseIf $string[1] = "Y" Then
        $output &= $yesterday[1] & $string[2]
    EndIf
    
    If $string[3] = "D" Then
        $output &= $yesterday[3] & $string[4]
    ElseIf $string[3] = "M" Then
        $output &= $yesterday[2] & $string[4]
    ElseIf $string[3] = "Y" Then
        $output &= $yesterday[1] & $string[4]
    EndIf
    
    If $string[5] = "D" Then
        $output &= $yesterday[3]
    ElseIf $string[5] = "M" Then
        $output &= $yesterday[2]
    ElseIf $string[5] = "Y" Then
        $output &= $yesterday[1]
    EndIf
    MsgBox (0, "", $output)
EndFunc

Thats perfect, if -1 is a valid day on your calendar.

You can't perform math on dates, there is an algorithm to determine valid dates hence the need for _DateAdd.
