My only comment is if your Date column is actually Date-Time then a minor tweak like the following is needed:
=COUNTIFS($D$3:$D$36,">="&INT($D3), $D$3:$D$36,"<"&INT($D3)+1, $E$3:$E$36,$E3)>1note: you can also replace $D$3:$D$36 with something like $D$3:.$D$999 where the period after the colon is a shortcut to the TRIMRANGE function to automatically find the end of the 'used' range so you can use this formula on columns of various length and/or continue to add rows and still have the formula work.
