def age_date(date)
  date.nil? ? 'n/a' : (date.to_age.to_s + ' / ' + format_date(date))
end

#format_date(start_date, full_date = false, options = {}) ⇒ Object

format a date or date range, using the same format for each date Mar 3, 2012 – Mar 5, 2012

options
 :format => specifies the localize format to use, rather than the default
 :ignore_year => don't display the year

end

#format_date_range(start_date, end_date, full_date = false, options = {}) ⇒ Object

We check the start_date year in case it’s a null date (set to a zero date, not just nil)
