Experts, I'm doing data backup and need to judge by the day of the week which corresponding files to compress. How should I write the batch file? I just looked it up and someone said to use %date%, but on my system %date% only returns the date and not the day of the week. What should I do? Waiting online

An update on the problem: the issue that %date% only returns the date has already been solved, but now a new problem has come up. For %date% to show the time, the system date format must be set to yyyy-mm-dd dddd, but my office system requires the date format to be yyyy-mm-dd. Is it possible to set it to yyyy-mm-dd dddd before the batch command runs, and set it back to yyyy-mm-dd after it finishes?

regedit -s DateFormatA.reg if %date:~-3%==Sunday call rar.bat pause regedit -s DateFormatB.reg pause In DateFormatA.reg, set the date format to yyyy-mm-dd dddd In DateFormatB.reg, set the date format to yyyy-mm-dd This doesn't work. The date doesn't get set back; it seems the second reg wasn't executed

@echo off rem Before executing the batch command reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /t REG_SZ /d "yyyy-mm-dd dddd" /f rem After executing the batch command reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /t REG_SZ /d "yyyy-mm-dd" /f
