I need a CF formula that compares each date in row 3 to the vertical holiday list on worksheet 'Holidays' and colors the cell(s) in row 3 when there is a match for the same WEEKNUM(nn,2) in range 'Holidays'$D$5:$D$40. &nbsp;The expected quantity of CF-colored dates should equal the 3-year range of the Holiday list... &nbsp;<br />
<br />
Attempted CF formula =WEEKNUM(L$3,2)=MATCH(WEEK<wbr />NUM(L$3,2)<wbr />,Holidays!<wbr />$D$5:$D$40<wbr />,1)... but this does not work correctly. Trying CF TEXT() formulas limits to only 3 correct 'hits' and only if using single-digit values in a series 1 to nn &nbsp;beneath the date series<br />
<br />
sample workbook attached has layout and &nbsp;several attempts with CF formulas<br />
