我将尝试从今天减去 60 天,但我不知道该怎么做。

我的约会对象是这样的:

@echo off
pause

SET currentYear=%date:~9,4%
ECHO %currentYear%
SET month=%date:~6,2%
ECHO %month%
SET day=%date:~3,2%
SET date=%day%%month%%currentYear%

ECHO %day%
ECHO %date%

pause

我浏览了互联网,但没有找到简单有用的东西!

最佳答案

试试这个:

@echo off
setlocal

Call :GetDateTime Year Month Day
Echo %Year% %Month% %Day%
Call :SubtractDate %Year% %Month% %Day% -60 Ret
echo %Ret%
exit /b


:SubtractDate Year Month Day <+/-Days> Ret
::Adapted from DosTips Functions::
setlocal & set a=%4
set "yy=%~1"&set "mm=%~2"&set "dd=%~3"
set /a "yy=10000%yy% %%10000,mm=100%mm% %% 100,dd=100%dd% %% 100"
if %yy% LSS 100 set /a yy+=2000 &rem Adds 2000 to two digit years
set /a JD=dd-32075+1461*(yy+4800+(mm-14)/12)/4+367*(mm-2-(mm-14)/12*12)/12-3*((yy+4900+(mm-14)/12)/100)/4
if %a:~0,1% equ + (set /a JD=%JD%+%a:~1%) else set /a JD=%JD%-%a:~1%
set /a L= %JD%+68569, N= 4*L/146097, L= L-(146097*N+3)/4, I= 4000*(L+1)/1461001
set /a L= L-1461*I/4+31, J= 80*L/2447, K= L-2447*J/80, L= J/11
set /a J= J+2-12*L, I= 100*(N-49)+I+L
set /a YYYY= I, MM=100+J, DD=100+K
set MM=%MM:~-2% & set DD=%DD:~-2%
set ret=%MM: =%/%DD: =%/%YYYY: =%
endlocal & set %~5=%ret%
exit /b

:GetDateTime Year Month Day Hour Minute Second
@echo off & setlocal
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"
( ENDLOCAL
IF "%~1" NEQ "" set "%~1=%YYYY%"
IF "%~2" NEQ "" set "%~2=%MM%"
IF "%~3" NEQ "" set "%~3=%DD%"
IF "%~4" NEQ "" set "%~4=%HH%"
IF "%~5" NEQ "" set "%~5=%Min%"
IF "%~6" NEQ "" set "%~6=%Sec%"
)
exit /b
