Have "Today" show instead of the todays date

My current agenda formula:

How can I have this read "Today - Roman's Birthday" instead without ruining the rest of the formula?

Use this $if(df(D) = df(D, ci(start, 0)), "Today", df(EEE M/d, ci(start, 0)))$, which translates to "if day of the year of today is same as day of the year of first calendar event write Today otherwise format as "EEE M/d"

I hear you're the man around these parts...thanks for getting back to me, I'll test when I get home from work...also, what if I want it to say "Tomorrow" as well within that same formula?
