How to find Yesterday?

[ioliver]

Is there a way to find out Yesterday's date (YYYYMMDD)? I look throught the Macro Reference - Time And Date section of the Help File, but I can't figure out how to do the calculations to get Yesterday's date.

Any help is apperciated.

Thanks,

Ian

Download the DateNew.au3 from my autoit stuff page and put it into the autoit3\include directory.

#include <DateNew.au3>
$yesterday = _DateAdd('d', -1, @YEAR & "/" & @MON & "/" & @MDAY)
MsgBox(4096, 'debug:', '$yesterday:' & $yesterday);### Debug MSGBOX

I need to do two things.

#1 - go back 13 calander days

#2 - format the return values as MMDDYY

I used this DateNew.au3 and it works great, but it would sure be neater if I had an array. I just can't figure out how to make one.

I need to do two things.

#1 - go back 13 calander days

#2 - format the return values as MMDDYY

I used this DateNew.au3 and it works great, but it would sure be neater if I had an array.  I just can't figure out how to make one.

Anyone care to assist? 

Something like this

#include <DateNew.au3>
Dim $Bck[13]
Dim $msg = ""
For $x = 0 To 12
   $Bck[$x] = _DateAdd('D', -1 - $x, @YEAR & "/" & @MON & "/" & @MDAY)
   $n_DATE = StringMid($Bck[$x], 6, 2)                ;get month
   $n_DATE = $n_DATE & StringMid($Bck[$x], 9, 2)      ;get wday
   $Bck[$x] = $n_DATE & StringMid($Bck[$x], 3, 2)    ;get year and replace Array value
   $msg = $msg & $Bck[$x] & @CRLF                    ;add to msg for magbox
Next
MsgBox(4096, 'Debug', $msg)

Are you able to link to the #include <DateNew.au3>. I am not able to locate it on your stuff. It could just be me...

UnknownUser,

Welcome to the AutoIt forums.

But do you realise that the post above yours is from 14 years ago? Please do not necro-post like this again.

And _DateAdd is now in the standard Date.au3 include file - which is why necro-posting is a bad idea as the language advances and past-requested functionalities might well be included in core or UDF code by now.
