It's a Rational:

(Date.new(2001,2,3) - Date.new(2001)).class
#=> Rational

and this is just how k's are displayed via inspect:

Rational(1)
#=> (1/1)

if you want an Integer, then just convert it to one:

(Date.new(2001,2,3) - Date.new(2001)).to_i
#=> 33

This is just a rational number:

(Date.new(2001,2,3) - Date.new(2001)).class
#=> Rational

You just got the number of days between the two date in rational format.
