Not all that arbitrary. It makes perfect sense to divide a lunar cycle in to a bright period and a dark period; both of those are about 14 days long. If you subdivide that further in to "bright growing brighter", "bright growing darker", "dark growing darker" and "dark growing brighter" phase, you end up with a month consisting of four seven day weeks.
