How do I format a date in ruby to include “rd” as in “3rd”

by

Unless you’re using Rails, add this ordinalize method (code shamelessly
lifted from the Rails source) to the Fixnum class

class Fixnum
  def ordinalize
    if (11..13).include?(self % 100)
      "#{self}th"
    else
      case self % 10
        when 1; "#{self}st"
        when 2; "#{self}nd"
        when 3; "#{self}rd"
        else    "#{self}th"
      end
    end
  end
end

Then format your date like this:

> now = Time.now
> puts now.strftime("#{now.day.ordinalize} of %B, %Y")
=> 4th of July, 2009
