I\'m in the U.S., and we usually format dates as "month/day/year". I\'m trying to make sure that my Rails app, using Ruby 1.9, assumes this format everywhere, and
Date.strptime is probably what you're looking for in ruby 1.9.
Date.strptime
You're probably stuck monkeypatching it onto string.to_date for now, but strptime is the best solution for parsing dates from strings in ruby 1.9.
Also, the formats are symmetric with strftime as far as I know.
