Yes. Here is my effort anyway:

require 'date'
require 'enumerator'

def days_to_show(year, month, num_week_rows)
  # returns an array of the dates in month,
  # with the last days of the preceding month
  # and the first days of the next month

  first_of_month = Date.new(year, month, 1)
  first = first_of_month - (first_of_month.wday)+1
  # +1 for weeks starting on monday, remove for weeks starting on sunday
  last = first + (num_week_rows * 7)
  (first...last).to_a
end

days = days_to_show(2008, 3, 6)
days.each_slice(7) do |week|
  print "| "
  week.each{|day| print day.to_s + "\t| "}
  puts
end

The only thing noteworthy is the range of dates, which produces an 
array.

Siep
