How To Sort Excel Pivot table chronologically

Question

I need help sorting my pivot table by months over a couple years. I've tried using a hyphen on the date column, a space.

My date column looks like this:

Could it be because yearMo is a calculated field?

I am using this formula: =CONCAT(L2,CONCAT(" ",M2))

The column datatype is 'date' . Thank you.

Answer 1

I don't think that excel recognizes your date, instead of the concat you could use

=date(M2,L2,1)

then custom format as M YYYY so you get the same result visually

The graph can thereby recognize it has a date to sort chronologically
