Below is a batch file that will wait for 1 minute, check the day, and then perform an action. It uses PING.EXE, but requires no files that aren't included with Windows.
@ECHO OFF
:LOOP
ECHO Waiting for 1 minute...
PING -n 60 127.0.0.1>nul
IF %DATE:~0,3%==Mon CALL SomeOtherFile.cmd
IF %DATE:~0,3%==Tue CALL SomeOtherFile.cmd
IF %DATE:~0,3%==Wed CALL SomeOtherFile.cmd
IF %DATE:~0,3%==Thu CALL WootSomeOtherFile.cmd
IF %DATE:~0,3%==Fri CALL SomeOtherFile.cmd
IF %DATE:~0,3%==Sat ECHO Saturday...nothing to do.
IF %DATE:~0,3%==Sun ECHO Sunday...nothing to do.
GOTO LOOP
It could be improved upon in many ways, but it might get you started.
