Question of batch file with if condition "and" / "or" in cmd

I would like to develop a batch file with the following condition:

1. Checking the DayOfWeek is whether equal to Mon - Fri --> (True) --> Copy ALL files --> (False) --> Go to check next condition
2. Checking the DayOfWeek is whether equal to Sat --> (True) --> Copy certain files --> (False) --> Go to check next condition
3. Checking the DayOfWeek is whether equal to Sun or public holiday --> Show an error message and exit

(Remark: My idea is put those date of public holiday store to the text file and get value to check on it.)

@ECHO OFF
FOR /F %%a IN ('Powershell -noP -c "(Get-Date).DayOfWeek.Value__"') DO SET week=%%a

IF %week% == "1" (GOTO ALLFOLDER) 
IF %week% == "2" (GOTO ALLFOLDER) 
IF %week% == "3" (GOTO ALLFOLDER)
IF %week% == "4" (GOTO ALLFOLDER)
IF %week% == "5" (GOTO ALLFOLDER)
IF %week% == "6" (GOTO CERTAINFOLDER)
IF %week% == "7" (ECHO ERROR! Script Exit!) EXIT(0)
