Count occasions when my birthday falls on a weekend - oracle

Question

I want to calculate how many times my birthday is on a weekend.
declare
v_count number;
v_birthday date := '22-07-1993';
v_sysdate date := sysdate;
begin
--1) first i have to know all the dates when it was my birthday till sysdate.
--2) then i have to convert it to a char(?) and look if its in the weekend (saturday or sunday)
--3) if yes, count have to be increased by one, if not, go to the next birthday till sysdate.
--4) show count in dbms.output_put_line(v_count);
-- ("for i_counter in 1..10 loop" and "while i_counter <=10 loop"
end;
I think I have to use a LOOP, but I only know LOOPs with numbers, not dates.

Answer 1

This code will count the number of days that JULY 22 will occur on a weekend (SATURDAY or SUNDAY) between 1993 and 2014 inclusive:
set serveroutput on size 100000
declare
V_DATE DATE;
I NUMBER;
WEEKEND_COUNT NUMBER;
begin
WEEKEND_COUNT := 0;
FOR I IN 1993 .. 2014
LOOP
V_DATE := TO_DATE('07/22/' || TO_CHAR(I), 'MM/DD/YYYY');
DBMS_OUTPUT.PUT_LINE(
'DATE: ' || V_DATE || ' ' ||
'DAY_OF_WEEK: ' || TO_CHAR(V_DATE, 'DY'));
IF TO_CHAR(V_DATE, 'DY') = 'SAT' OR
TO_CHAR(V_DATE, 'DY') = 'SUN' THEN
WEEKEND_COUNT := WEEKEND_COUNT +1;
END IF;
END LOOP;
DBMS_OUTPUT.PUT_LINE ('NUMBER OF BIRTHDAYS ON WEEKENDS: ' ||
WEEKEND_COUNT);
end;
The output is:
