Showing only columns with data...

Hello and Good Day,

I have 3 columns of information.

In column a, I have a helper row (I think that's what it is called) to show a number if the cell next to it in row B contains information. In column C is where I would like the information to be displayed. The trick is, I would like the information in column C to begin on the first row as the information in column B (Based on criteria of month and date) expires throughout the course of the month. How can this be done?

I have attached an example...

Once again I call upon the help of the experts, and once again, thank you.
