Here's one for fun.  I'm pretty sure you don't want to use this (for
all I know, you might be laughed out of the room :), but it
demonstrates some methods...

require 'enumerator'
o = (t = Date.today).wday
c = (-1..1).inject([]) {|a, i| a << (t.month + i)}.map {|i|
1..Date.new( t.year, i, -1 ).day}.map {|i| i.to_a}
o.times {c[1].unshift c[0].pop}
c[1..2].flatten.slice(0..35).compact.each_slice(7) {|i| p i}

You'd have to tidy up the output of course (using #join or whatever).
Also, as you can see, 5 weeks doesn't necessarily cover a month. In
March's calendar for 2008, there are 6 days out of February.
