Answer 1

Declare @t table(StartDate date ,Year1 int)
insert into @t values('04/01/2012',2013),('01/01/2012',2012),('09/15/2013',2014)
;with CTE as
(select max(year1) maxyear from @t)
, cte1 as
 (select cast('04/01/'+convert(varchar(4),a.year1) as  date) FromFY,dateadd(day,-1,dateadd(year,1,cast('04/01/'+convert(varchar(4),a.year1) as date))) ToFY


,b.year1 from @t a  inner join (select min(year1)year1 from @t) b on a.year1=b.year1
    union all
   select cast(dateadd(day,1,ToFY) as date),cast(dateadd(year,1,ToFY) as date),year1+1 year1 from     cte1 where year1<=(select maxyear from cte)
)
