I think a rather nice way of doing this is "by example":

def loop_over(v1,v2,vn)
   x = v1
   step = v2 - v1
   while x <= vn
     yield x
     x += step
   end
end

loop_over(1,2,10)  {|x| puts x} # -> 1,2,3,4,5,6,7,8,9,10

day = 60 * 60 * 24
t = Time.now

loop_over(t, t + day, t + 7*day) do |weekday|
