Here's a batch file I developed to subtract any number of days from the current date. It accepts a command line parameter of the number of days. The default is 1 day (yesterday):

@echo off

set yyyy=

set $tok=1-3
for /f "tokens=1 delims=.:/-, " %%u in ('date /t') do set $d1=%%u
if "%$d1:~0,1%" GTR "9" set $tok=2-4
for /f "tokens=%$tok% delims=.:/-, " %%u in ('date /t') do (
 for /f "skip=1 tokens=2-4 delims=/-,()." %%x in ('echo.^|date') do (
    set %%x=%%u
    set %%y=%%v
    set %%z=%%w
    set $d1=
    set $tok=))

if "%yyyy%"=="" set yyyy=%yy%
if /I %yyyy% LSS 100 set /A yyyy=2000 + 1%yyyy% - 100

set CurDate=%mm%/%dd%/%yyyy%

set dayCnt=%1

if "%dayCnt%"=="" set dayCnt=1

REM Substract your days here
set /A dd=1%dd% - 100 - %dayCnt%
set /A mm=1%mm% - 100

:CHKDAY

if /I %dd% GTR 0 goto DONE

set /A mm=%mm% - 1

if /I %mm% GTR 0 goto ADJUSTDAY

set /A mm=12
set /A yyyy=%yyyy% - 1

:ADJUSTDAY

if %mm%==1 goto SET31
if %mm%==2 goto LEAPCHK
if %mm%==3 goto SET31
if %mm%==4 goto SET30
if %mm%==5 goto SET31
if %mm%==6 goto SET30
if %mm%==7 goto SET31
if %mm%==8 goto SET31
if %mm%==9 goto SET30
if %mm%==10 goto SET31
if %mm%==11 goto SET30
REM ** Month 12 falls through

:SET31

set /A dd=31 + %dd%

goto CHKDAY

:SET30

set /A dd=30 + %dd%

goto CHKDAY

:LEAPCHK

set /A tt=%yyyy% %% 4

if not %tt%==0 goto SET28

set /A tt=%yyyy% %% 100

if not %tt%==0 goto SET29

set /A tt=%yyyy% %% 400

if %tt%==0 goto SET29

:SET28

set /A dd=28 + %dd%

goto CHKDAY

:SET29

set /A dd=29 + %dd%

goto CHKDAY

:DONE

if /I %mm% LSS 10 set mm=0%mm%
if /I %dd% LSS 10 set dd=0%dd%

echo Date %dayCnt% day(s) before %CurDate% is %mm%/%dd%/%yyyy%

Good Luck,
Steve
