Does anyone have insights into the relationship between moon phases, the elemental relationship between days and hours, and their effects on crafting?

Moon phases appear in the upper righthand corner of the screen, and they do seem to have some effect on crafting success rates -- with certain players favoring certain moon phases, perhaps determined by your guardian, birth date, or even race? With observation, you can figure out which moon phases work better for you and which to avoid if possible.

But elemental alignment is still a big mystery. I have read that some days and some hours are aligned with certain elements, and indeed performing a synthesis during certain hours just seems destined for failure no matter what abilities I apply. There seems to be no way to tell which element is currently dominant.

I hope someone here is more insightful than I am, and has managed to make sense out of these aspects of crafting.
