    This is my solution for you, in case you work with I18n-based projects, that requires multilingual features:

    def month_array
      # Gets the first day of the year
      date = Date.today.beginning_of_year
      # Initialize the months array
      months = {}
    
      # Iterate through the 12 months of the year to get it's collect
      12.times do |i| # from 0 to 11
        # Get month name from current month number in a selected language (locale parameter)
        month_name = I18n.l(date + i.months, format: '%B', locale: :en).capitalize
        months[month_name] = i + 1
      end
      return months
    end
    
    # => {"January"=>1, "February"=>2, "March"=>3, "April"=>4, "May"=>5, "June"=>6, "July"=>7, "August"=>8, "September"=>9, "October"=>10, "November"=>11, "December"=>12}
    

    Regards
