Return just the last day of each month with SQL

I have a table that contains multiple records for each day of the month, over a number of years. Can someone help me out in writing a query that will only return the last d

This should work on Oracle DB

select  distinct last_day(trunc(sysdate - rownum)) dt

  connect by rownum < 430
   order by 1
