Windows console

Question

I would like to set the date in a Windows batch file to 7 days ago from today. I would like to do this in the following format.

Answer 1

AdamEstrada asked about subtracting dates. I had a tough time subtracting two Julian dates because of the SETLOCAL in the Julian functions. I did it by calling a function.

call:sub_Julians !Julian! %Today_Julian%

:sub_Julians

set /a delta_dates=%~1-%~2

...

goto:eof ::end:age_of_EPSdate
