Any anniversary today?

SELECT *
FROM your_table_with_timestamp_column
WHERE EXTRACT(DAY FROM your_column) = EXTRACT(DAY FROM now())
AND EXTRACT(MONTH FROM your_column) = EXTRACT(MONTH FROM now())
AND your_column <= now(); -- prevent to show events that will
be in the future

Or May 5th:
SELECT *
FROM your_table_with_timestamp_column
WHERE EXTRACT(DAY FROM your_column) = EXTRACT(DAY FROM TIMESTAMP
'2008-05-05')
AND EXTRACT(MONTH FROM your_column) = EXTRACT(MONTH FROM TIMESTAMP
'2008-05-05')
AND '2008-05-05'::timestamp <= now(); -- prevent to show
events that will be in the future

Sorry, if I misunderstood your question.
