This is because you’ve accidentally input the values as text somewhere along the line. First make sure your format is set to date in the range in question.
Make use of the DATEVALUE formula in blank column =DATEVALUE(your_range). This will output your range as a number. Note that your_range needs to be in your computers date format (I have mine set to YYYY.MM.DD, so that what I have to use, else it won’t work. You might be American, so your dates would need to be MM/DD/YYYY) for DATEVALUE to recognise the text as a date string.
Then copy the output, paste as values only (alt, h, v, v), then copy that and paste it back into you range.
Make sure the format is set to date and you’re laughing.

The solution for that is using a sane format for dates.

When I worked in radio production, basically everything was formatted like YYYY-MM-DD. Which means stuff is really to find and properly in chronological order.
I still usw the MM-DD format for my own file formatting, even though DD-MM is the Dutch standard.
YYYY-MM-DD is god’s perfect date notation as far as I’m concerned.

Yeah - I don’t get to determine what date format 3rd party reports are generated in before I import into excel.
But excel has formatting options specifically designed to address this that it just ignores half the time.
