Answer 1

If I get the question right, with [:start, :end] being your date range of interest, you're looking for:

select *
 from event
where -- event started earlier, ends later
      start <= :start and :start <= end
   or -- event starts during [:start, :end]
      :start <= start and start <= :end
   or -- event ends during [:start, :end]  
      :start <= end and end <= :end;

If you're looking for a particular :day, use :day as :start and :day + 1 day as :end.
