从日期中获取日期名称

Question

我想显示给定日期的星期几。我有一个代码可以根据系统日期给我名字的日期。

@for /F "tokens=1 delims=, " %%i In ('powershell date') do set dow=%%i
echo %dow%

我怎样才能显示我要输入的任何日期的日期名称？我想做这样的事情（我已经在之前设置了变量日，月和年）：

@for /F "tokens=1 delims=, " %%i In ('powershell %day%/%month%/%year%') do set dow=%%i
echo %dow%

改编自https://technet.microsoft.com/en-us/library/ff730960.aspx：

for /f "delims=" %%d in ('powershell (get-date  %day%/%month%/%year%^).dayofweek') do set dow=%%d

出于测试目的：

@echo off
:...
echo Command line: powershell (get-date  %day%/%month%/%year%).dayofweek
echo Result:
powershell (get-date  %day%/%month%/%year%).dayofweek
for /f "delims=" %%d in ('powershell (get-date  %day%/%month%/%year%^).dayofweek') do set dow=%%d
echo dow=%dow%
