The eight day system stands out though as it's the Buddhist equivalent of sabbath. They valued lunar patterns (many went to their mass at night) and moon phases marked temple days, which they based an eight-day division on, while the weird daytime divisions were common in every culture until the clock was invented. The six day week is used because six is the most useful one-digit number when making unitary constructs, not so much with time in particular in mind (whether it divides into 365 was not contemplated anymore than whether the traditional seven does, with the earliest recorded year being rooted in archaeology, though yes it's not unquestionable except for the fact that the next best conclusion I'm aware of would be that something like the Toba super-eruption should be the starting point, and there is difficulty in that).

The thing about aesthetics is, while things that are useful could be said to be anti-aesthetic, things that are aesthetic could be said to be anti-useful (think handwriting versus print; one is far more practical). Both may be satisfying, but only one can go places. Admittedly it's a rough balance between natural and mathematical aspects of time, albeit it wouldn't have it any other way.
