I need a query to list all dates in the last 6 months.
for example eg. we're currently in November,  so if i ran the query today it would list dates back to May. The first date always needs to be a friday so in this instance it will return the 1st Friday before the 1st of May (or return the 1st of may if its a friday), the last day would be the last friday before today (or today if today was friday). I hope this makes sense - i'll include some sample data which will hopefully make my requirments clearer.

try this...

select next_day(add_months(trunc(sysdate,'mm'),-6)-7,'Friday') + level - 1 d from dual
connect by next_day(add_months(trunc(sysdate,'mm'),-6)-7,'Friday') + level <= sysdate

I'm trying, I really am. But I've seen so many wrong approaches involving date(time) boundaries I despair about my inability to explain it. I've seen quite a few recently that define a non-leap year as 364 days, or 366 days and the list goes on. …
