Duplicate Keys in Hash throw a warning

Starting a rails (3.2) app using Ruby 2.2 output the following:

yada/yada/yada/.rvm/gems/ruby-2.2.6@gemsetname/gems/timetwister-0.2.5/lib/timetwister/utilities.rb:124: warning: duplicated key at line 138 ignored: "marzo"

I know those month names exist in multiple languages but maybe you can move it to a unique key with a comment letting folks know the languages.

Sounds like a plan; I'll remove it from redundant languages and note the gap.
