I am using Excel 2013. I have a worksheet that has training completion dates for our employees. I need to determine the percentage of employees that have completed the training. I am using the below COUNTIF formula, but the return is a 0 even though the majority of dates are after 1/1/2018.
=COUNTIF(J9:J444,">=1/1/2018")
I thought maybe the excel report I am exporting from our tracking system is putting the dates in an unrecognized format but the below formula works just fine:
=IF(J9>=1/1/2018,"YES","NO")
Am I using the wrong format for the COUNTIF function? I don't think I am because excel is not giving me an error, it is just returning a 0.
Thank you for your assistance! -Curtis
