"the obvious way to keep track of their comings and goings is to count the days passing, which gives you a 365 day calendar." it doesnt seem obvious to me, how exactly do you know when to stop counting? i mean how do you know when its starting to repeat? by measuring the lengths of consecutive nights and counting how many days have passed since one summer solstice to the next one? haha have i answered myself?
