highlight cell through conditional formatting if the date matches ?

Hi to all experts,

i am trying to define a conditional formatting that if any date of Column C matches to cell B4 then the selected cell must be highlighted in yellow color and this function should keep on working with my upcoming dates. (manually highlighted with yellow color) as a result i am looking for.

actually i defined this earlier but i do not know when my B4 value reached to 2019 the highlighted cell disappeared. i used =IF(WEEKNUM($C7,16)=WEEKNUM(TODAY(),16),1,0).

i attached the example sheet for reference.

thanks in advance

i tried your solution but does not work

i tried the formula =$A$7:$CC$187=$C7=$B$4 to CF by selecting the range as shown.

but my row are not getting highlighted.

for reference i attached the worksheet containing the above formula.

Thanks...... the mistake was mine that i was not placing the correct values to CF.

Thanks again
