Highlighting range of cells based on start and end dates

[d0gp1l3]

Hi

New to this.
I am trying to highlight a range of cells based on the start and end dates in 2 othe columns.

I.e. Column B contains Start date, Column C contains End date.
Row 2 contains Dates for 2012 by days

I would like to be able to highlight the repective cells green when a start and end date are entered.

Thank you in advance
