Is there coding for showing which Member customers have birthdays in a particular month?

Can coding be built into the CSV to highlight a Member’s Birthday Month? For example, Month ____ Day____ Year ____ which will trigger when the Member’s Birthday Month is reached? 2 conditions are needed (The customer is a Member & it is their Birthday Month). When I type in a search for Customer “X”, for example, could I see a small note on the side showing - Customer “X” & - his Birthday Month?
