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.
