任意一个日期将其转换成相应的星期的代码怎么写。
如：2008/02/26
转换得到：星期二

vbs的话很简单就1~2条命令,但是现在还不知道函数
稍等~

datepart("w",date)
作者: qnaqwtwc 时间: 2008-2-26 13:40 标题: 回楼上
datepart("w",date)
这命令行似乎不行，命令err.

aDate = InputBox("请输入一个日期：", "BY: fastslz",date)
aWeek = DatePart("w", aDate)
Select Case aWeek
Case 1 Wscript.Echo "星期天"
Case 2 Wscript.Echo "星期一"
Case 3 Wscript.Echo "星期二"
Case 4 Wscript.Echo "星期三"
Case 5 Wscript.Echo "星期四"
Case 6 Wscript.Echo "星期五"
Case 7 Wscript.Echo "星期六"
End Select
aWeek = DatePart("w", aDate)
Select Case aWeek
Case 1 Wscript.Echo "星期天"
Case 2 Wscript.Echo "星期一"
Case 3 Wscript.Echo "星期二"
Case 4 Wscript.Echo "星期三"
Case 5 Wscript.Echo "星期四"
Case 6 Wscript.Echo "星期五"
Case 7 Wscript.Echo "星期六"
End Select

以上代码是让我保存成bat来运行吗？还是其他

vbs
作者: fastslz 时间: 2008-2-26 14:36
我不是说了吗，vbs
这个bat的
@echo off
>tmp.vbs Echo aDate = InputBox("请输入一个日期：", "BY: fastslz",date)
>>tmp.vbs Echo aWeek = DatePart("w", aDate)
>>tmp.vbs Echo Select Case aWeek
>>tmp.vbs Echo Case 1 Wscript.Echo "星期天"
>>tmp.vbs Echo Case 2 Wscript.Echo "星期一"
>>tmp.vbs Echo Case 3 Wscript.Echo "星期二"
>>tmp.vbs Echo Case 4 Wscript.Echo "星期三"
>>tmp.vbs Echo Case 5 Wscript.Echo "星期四"
>>tmp.vbs Echo Case 6 Wscript.Echo "星期五"
>>tmp.vbs Echo Case 7 Wscript.Echo "星期六"
>>tmp.vbs Echo End Select
for /f "delims=" %%i in ('cscript.exe //nologo tmp.vbs') do set aDate=%%i&del tmp.vbs
Echo %aDate%
pause
>tmp.vbs Echo aDate = InputBox("请输入一个日期：", "BY: fastslz",date)
>>tmp.vbs Echo aWeek = DatePart("w", aDate)
>>tmp.vbs Echo Select Case aWeek
>>tmp.vbs Echo Case 1 Wscript.Echo "星期天"
>>tmp.vbs Echo Case 2 Wscript.Echo "星期一"
>>tmp.vbs Echo Case 3 Wscript.Echo "星期二"
>>tmp.vbs Echo Case 4 Wscript.Echo "星期三"
>>tmp.vbs Echo Case 5 Wscript.Echo "星期四"
>>tmp.vbs Echo Case 6 Wscript.Echo "星期五"
>>tmp.vbs Echo Case 7 Wscript.Echo "星期六"
>>tmp.vbs Echo End Select
for /f "delims=" %%i in ('cscript.exe //nologo tmp.vbs') do set aDate=%%i&del tmp.vbs
Echo %aDate%
pause

好的谢谢

bat版本的:
@echo off
:支持2008年,其他年份算法类似
:没有容错处理
:s
set "mod=145136140250"
set /p rq=输入:月/日[例:3/26]
for /f "delims=/ tokens=1,2" %%a in ("%rq%") do set d=%%b&call set n=%%mod:~,%%a%%
set s=%n:~-1%
set/a w=(%d%+%s%)%%7
if %w% equ 0 set w=日
echo 2008/%rq%这一天是:星期%w%&echo.
goto :s
其实关于星期计算有::支持2008年,其他年份算法类似
:没有容错处理
:s
set "mod=145136140250"
set /p rq=输入:月/日[例:3/26]
for /f "delims=/ tokens=1,2" %%a in ("%rq%") do set d=%%b&call set n=%%mod:~,%%a%%
set s=%n:~-1%
set/a w=(%d%+%s%)%%7
if %w% equ 0 set w=日
echo 2008/%rq%这一天是:星期%w%&echo.
goto :s
基姆拉尔森计算公式
W= (d+2*m+3*(m+1)/5+y+y/4-y/100+y/400) mod 7
在公式中d表示日期中的日数＋1，m表示月份数，y表示年数
只是这个算法比上面的算法复杂,代码也长.
