Highlighting duplicate data based on two conditions


I want to make a formula to highlight whenever to cells contain the same data on the same date. I'm working with a marketing calendar and want to find a way to highlight whenever two campaigns are planned to go out to the same country on the same date. So, if two (or more) cells contain the same date as well as the same country locales. 

The only formula I can find is to check if there are duplicates in ONE column, but I want to check all columns against each other. 

I have created a helper column in which to place the formula and thinking to make conditional formatting, once it's ready. The conditional formatting should apply if more than one row has identical data in cell 1 (date) and cell 2 (country).

Is this possible?
