Maybe I am missing something but you are simply decrementing the day by one. There is nothing here to handle month or year transitions. Too bad one cannot get to the epoch time as with Linux.
: Use the /A option in the Set dwday line of your file as below and note the -1 to decrement the day by 1.
: SETLOCAL
: SET dwMONTH=%DATE:~4,2%
: SET /A dwDAY=%DATE:~7,2%-1
: SET dwYEAR=%DATE:~10,4%
: SET dwDate=%dwYEAR%-%dwMONTH%-%dwDAY%
: ECHO %dwYEAR%-%dwMONTH%-%dwDAY%
: ECHO %dwDate%
: See this site for other arithmetic operators. http://www.robvanderwoude.com/ntset.html
: Good luck
