Using Excel 2016 on Windows 10.1803. Is there any way to permanently set the default date format to mm/dd/yyyy? I know how to adjust the format AFTER I enter a date, but the only format I ever use is mm/dd/yyyy, and 3-Sep never made any sense as a usable date anyway. Is there some way to set the default, so I don't have to change the format every time I add a column with dates in it?
