In Rails, display time between two dates in English

Question

In a Rails project I want to find the difference between two dates and then display it in natural language. Something like

>> (date1 - date2).to_natur         


        

Answer 1

def date_diff_in_natural_language(date_from, date_to)
  components = []
  %w(years months days).each do |interval_name|
    interval = 1.send(interval_name)
    count_intervals = 0
    while date_from + interval <= date_to
      date_from += interval
      count_intervals += 1
    end
    components << pluralize(count_intervals, interval_name) if count_intervals > 0
  end
  components.join(', ')
end
