＃handle invalid date 
 end 
 

Say I have a string: "31-02-2010" and I want to check see whether or not it is a valid date or not. What is the best way to do it?

I need a method which I can call on string which returns true if the string is a valid date and false if it is not.

require 'date'
begin
   Date.parse("31-02-2010")
rescue ArgumentError
   # handle invalid date
end
