The lunar calendar offers no advantage or benefit, compared to the one thatwe're using.The moon goes through its complete set of phases 12.368 times in one year. So if you're going to flip your calendar to a new month each Full Moon, let's say, then after 12 of them, you still have 10.9 days left until another year begins. So #1). you have to figure out something creative to do with 10.9 days, and #2). the next year won't start with a Full Moon.It's just too messy, trying to invent a schedule that matches up with the moon phases and the seasons both. And since the whole process of producing food in order to avoid starvation is closely tied in with the seasons but not with themoon phases, every civilized culture eventually came around to using a solar calendar, rather than a lunar one.
Accepted Answer
The seasons affect the schedule of more events than the moon phases
