How to place enter in function.php?

I have a code :
// [date]
function displaydate(){
return date(‘F jS’);
}
add_shortcode(‘date’, ‘displaydate’);
// end date

This displays in my page like: June 13th
But i want is like:
June
13th

I tried to use
tags and \n in the code.
If i am useing \n than i get something like this:

June
n13th

How do i get rid of the “n”?
