Your Array should really contain Date instances and not String 
instances.  Usually parsing is done when the data is read from some 
external source (command line, file, prompt) so you can continue to work 
with proper methods of the particular type.

Not sure what you mean.  Is it this?

irb(main):003:0> Date.strptime("24 Aug 2010", "%d %b %Y")
=> #<Date: 2010-08-24 (4910865/2,0,2299161)>
irb(main):004:0> Date.strptime("24 Aug 2010", "%d %b %Y").to_s
=> "2010-08-24"

Kind regards
