I know how to return current date like below.


set year=%date:~10,4%
set month=%date:~4,2%
set day=%date:~7,2%

echo %month%-%day%-%year%


but now I need to return yesterday's date. is it possible?

yes its possible to do with batch BUT at the expense of losing your brain cells.
try using vbscript

Probably the "easiest" way is dos is to convert to a julian date, subtract 1, and convert back to "normal" date using the various subroutines from this website:
