the problem is that you're using the same week array. Here's another  
solution for the same problem:

def cal_week(month, year = Date.today.year)
   fotm = Date.new(year,month,1) # first of the month
   lotm = (fotm >> 1) - 1 # last of the month
   weeks = []
   week = []
   fotm.upto(lotm) do |d|
     week[d.wday] = d.day
     if d.wday == 6
       weeks << week
       week = []
     end
   end
   weeks << week unless week.empty?
end

p cal_week(4)
