While philosophers debate whether the glass is half empty or half full, Excel is over here interpreting your liquid level as a date because why not? This perfectly captures Excel's notorious habit of converting anything remotely numeric into dates whether you want it to or not. Type "1/2" meaning one-half? Nope, that's January 2nd now. Your simple fraction? Sorry, it's February 1st. The eternal struggle of every data analyst who's ever screamed at their screen: "NO EXCEL, THAT'S NOT A DATE!"
