I want to make a batch file that designated as a folder name date of a previous day.How can I do?

Here is my batch file.

Set Tarih1=%date:.=%


cd  Yeni Klasör

md %date:.=%

cd %date:.=%

thanks in advance.

Solution :

It’s possible, but…

set _today=%date:.=%
set _year=%_today:~0,4%
set _month=%_today:~4,2%
set _day=%_today:~6,2%

:: leap year?
set /a _yearm400=_year %% 400
set /a _yearm100=_year %% 100
set /a _yearm4=_year %% 4

if %_yearm400% equ 0 (set _leap=1) ^
else (if %_yearm100% equ 0 (set _leap=0) ^
else (if %_yearm4% equ 0 (set _leap=1) ^
else (set _leap=0)))

:: strip leading zeros
if %_month:~0,1% equ 0 set _month=%_month:~1%
if %_day:~0,1% equ 0 set _day=%_day:~1%

:: decrement day
set /a _day-=1

:: decrement month
if %_day% equ 0 (
    if %_month% equ 2 set _day=31
    if %_month% equ 3 set /a _day=28+_leap
    if %_month% equ 4 set _day=31
    if %_month% equ 5 set _day=30
    if %_month% equ 6 set _day=31
    if %_month% equ 7 set _day=30
    if %_month% equ 8 set _day=31
    if %_month% equ 9 set _day=31
    if %_month% equ 10 set _day=30
    if %_month% equ 11 set _day=31
    if %_month% equ 12 set _day=30
    if %_month% equ 1 set _day=31
    set /a _month-=1

:: decrement year
if %_month% equ 0 (
    set /a _year-=1
    set _month=12

:: format new date
if %_month% leq 9 set _month=0%_month%
if %_day% leq 9 set _day=0%_day%

echo %_year%%_month%%_day%

I suggest using a more capable programming languages – PowerShell, maybe Python or Perl.


$yesterday=(get-date (get-date).AddDays(-1) -uformat %Y%m%d)
mkdir $yesterday


import os
import time
yesterday = time.strftime("%Y%m%d", time.localtime(time.time() - 86400))

Also, when changing drives, you must use only the drive letter, without a path. d: should be replaced with d: … Or just use cd /d D:Yeni Klasör.

If you really don’t want (or can’t) use Powershell, then you could do it calling a .vbs (VBScript file)

File CreateYesterdayFolder.vbs

' yyyymmdd.vbs - outputs the current date in the format yyyymmdd
Function Pad(Value, PadCharacter, Length)
Pad = Right(String(Length,PadCharacter) & Value, Length)
End Function

Dim yesterday, folderName

yesterday = Date() - 1
folderName = Pad(Year(yesterday), "0", 4) & Pad(Month(yesterday), "0", 2) & Pad(Day(yesterday), "0", 2)

Dim objFSO, objFolder, strDirectory
newDirPath = "c:temp" &

folderName ' example
