How to extract Day of Week

Message

I suppose I'm missing something really obvious, but I can't find much on date formats. I need to determine the day of the week from %DATE% and set a variable to format such as MONDAY, TUESDAY, etc. Note that I also need the day in caps.

Thanks for the info. Much more elaborate than the simple approach I ended up taking:

set day=%DATE:~0,3%

IF %day% == Mon set dayofweek=Monday
IF %day% == Tue set dayofweek=Tuesday
IF %day% == Wed set dayofweek=Wednesday
IF %day% == Thu set dayofweek=Thursday
IF %day% == Fri set dayofweek=Friday
IF %day% == Sat set dayofweek=Saturday

Just remember -- not all OS version actaully include the DAY in the %date% variable

Alternatively use Julian days modulo seven to look up a string like this:

Code: Select all

@Echo Off

call:jdate JD
set /a d=1+(JD%%7)
for /f "tokens=%d%" %%A in ("MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY SUNDAY") do echo.%%A

GOTO:EOF


::-----------------------------------------------------------------------------------
::-- Functions start below here
::-----------------------------------------------------------------------------------


:jdate JD DateStr -- converts a date string to Julian day number with respect to regional date format
