Check Month year if exists

I have a column called Recevieddate (datetime). I have a string '2/1/2015'. I want to check if month and year exists in Recevieddate when I pass @mydate. Date does not matter.


Sample date

2015-02-01 00:00:00.000
2015-02-06 00:00:00.000
2015-03-05 00:00:00.000
2015-04-15 00:00:00.000



declare @mydate varchar(12)
set@mydate = '2/1/2015'
declare @tf    char(1)


if exists(select *from table1 where receiveddate = @mydate ???)
  begin
    set @tf = 'True'
  end
  else
  begin
    set @tf = 'false
  end


Sample
2/1/2015 should return true because month year exists in Recevieddate
2/15/2015 should return true
