Filter Miss-Matched Dates Between 2 Columns

I have 3 times series data in excel (returns on stock, market return and risk free return), each has their own date corresponding to its return, so 6 columns all up.

Imagine it like this:
Date | Stock Return -- Date | Market Return -- Date | Risk Free Return

The problem is that the 3rd data set (risk free return), its date column mismatch the dates column of the first two (returns on stock and market). So the obviously solution is to basically get the third time series data to only show the same dates as the first two.

I want to use the first two data sets date's as like a benchmark for the third data set to only show those dates.

I have tried filter/advanced filter in Excel 2007 and spent ages on google/youtube but no luck; it wont let me try to match specific cells to filter out dates from a specific series of cells.
