displaying people's birthday with users selected day

Dear Abap Experts.

Suppose at a select options field any date can be

choosen or selected up to you. In the next field you can

select a weekday. And now the requirement is

to select "all the people" where have their birthday

on the users selected weekday (e.g. Tuesday) and starting from the

selected date. Only the birthdays where are on tuesdays.

How can this requirement be implemented ?
