It strikes me that week is a fairly artifical unit, being intermediate between
a day (roughly one sleep-wake cycle) and a month (roughly one lunar
cycle), not not really being significant otherwise. Though, if the orcs have
evolved underground, I'm not so sure the queen's cycle would be related
to the lunar cycle...
