如何突出显示指定范围内的日期？

Question

I have one column ( A ) of dates in Excel, each row representing one day of the year. I want to highlight a date if it's included in a list of dates ( $C$3:$C$28 ) on the same page.

I want the date highlighted if it's a pay date that occurs every second Friday (every other Friday). I don't want to manually go through and select them piecemeal.

I've tried conditionally formatting the range by going to "Conditional Formatting" > "Highlight Cell Rules" > "Equal To" and specifying $C$3:$C$28. This obviously doesn't work.

Is there a conditional formatting formula I can plug in to highlight pay dates in my data range? Or, is there a macro that I can use?

Answer 1

How about: "Conditional Formatting" > "Highlight Cell Rules" > "Duplicate Cell Values" and select all of Column A and $C$3:$C$28

It will highlight both columns A and C, but A will be highlighted.

Answer 2

A CF formula rule of:

=AND(WEEKDAY(A1)=6,MOD(COUNT(A$1:A1),2))  

should work for every other Friday.

For the other Fridays from the above:

=AND(WEEKDAY(A1)=6,NOT(MOD(COUNT(A$1:A1),2)))
