Or at a higher level:

require 'date'
birthday = Date.parse(gets)
puts birthday.day, birthday.month, birthday.year

Warning: this accepts a lot of formats, including the unambiguous 
yyyy/mm/dd, but seems to default to American middle-endian dates.

irb(main):013:0> birthday = Date.parse("01/02/2003")
=> #<Date: 4905283/2,0,2299161>
irb(main):014:0> puts birthday.day, birthday.month, birthday.year

2003
