Have you noticed that these are 2011-10-05 and you said in the first sentence
2011-05-10.
Depending on which version of Ruby, a/b/YYYY where both a<=12 and b<=12,
sometimes a is the month and sometimes b is the month.
Your first issue is parsing the date format as input from the user.
Take a look at Date#strptime
irb(main):003:0> Date.strptime('5/10/2011', '%m/%d/%Y').to_s
=> "2011-05-10"
irb(main):004:0> Date.strptime('5/10/2011', '%d/%m/%Y').to_s
=> "2011-10-05"
