Usual chaldean order:
Saturn Jupiter Mars Sol Venus Mercury Luna
This is the order, slowest to fastest, of their apparent speed of movement. It's basically the order used everywhere for everything; it's what our eyeballs could see.

Weekday order:
As above, skipping by 3. Or by arranging the above clockwise in a circle, drawing a heptagram between them, and following the heptagram's lines.
---
Enochian order:
Venus / Friday
Sol / Sunday
Mars / Tuesday
Jupiter / Thursday
Mercury / Wednesday
Saturn / Saturday
Luna / Monday
It's almost skipping forward by 2's, but Mercury would need moved to the end for that to work. Mercury has a way of being a dick like that.
I have no idea how this order came about but there is internal consistency:
where a prince of a given planet is 'X of Y', the following planet's king is invariably 'X of X', and they're following this same order.
e.g.:
Venus of Venus (King)
Sol of Venus (Prince)
...
Sol of Sol (K)
Mars of Sol (P)
...
Mars of Mars (K)
Jupiter of Mars (P)
...
Mercury of Jupiter (P)
Saturn of Mercury (P)
Luna of Saturn (P)
Venus of Luna (P)
The next king ofc is back to the top with Venus of Venus, and all the Governers are the same order, still, for any given planet. This is all rather similar to how planetary hours work but those use the chaldean order and there's 12 hours per day/night and aside from 'follows a cycle' isn't really relevant.
But I can't work with things I don't grok so for shits and giggles I also arranged this order with a heptagram, the way the week day order can be derived from the chaldean order. See attachment. Considering he's possibly (not likely, but supposedly attributed) the author of "The Little Book of Black Venus" ( http://jwmt.org/v2n12/venus.html ) and most definitely the author of the Heiroglyphic Monad (regardless what the text says, if you just stare at it off hand I'm sorry but it looks like a buncha shit added to venus), this arrangement basically reeks of Dee.
I don't know if this arrangement is at all relevant, but just tossing mercury to the end of the series between luna and venus would definitely cock up the nice thing where blatant opposites aren't directly in line with eachother.

Chaldean order: Saturn Jupiter Mars Sol Venus Mercury Luna
Backwards: Luna Mercury Venus Sol Mars Jupiter Saturn
Backwards, Venus origin: Venus Sol Mars Jupiter Saturn Luna Mercury
Enochian/Dick-Mercury: Venus Sol Mars Jupiter Mercury Saturn Luna
Aside from Saturnday, Sunday, and Monday. The rest of the names of the days of the week come from the Norse and Germanic traditions. Tuesday is named after Tyr ( a war god), Wednesday is named after Wotan (trickster and psychopomp), Thursday is named after the Thurses (or Thurs Giants, not Thor), and Friday after Freya (love goddess). The planetary attributes came after the Romans spent time in the Germanic lands and compared the Northern gods to their own.
Most classic example is with Odin/ Wotan and how they compared him to the Roman god Merurius. Both would communicate messages to mankind, both were tricksters, both sought knowledge and were lords of magic, and both were psychopomps for the dead. Because of this Tacitus naturally stated that they are one and of the same. So Wotan and Mercurius would assimilate into each other. And what better way to bring a subjugated people under your rule than to turn their god into your god.. So Wotan and Mercurius melded. And Wotan became associated with the planet Mercury. And the day of Mercury became Wotansday or Wednesday. Granted there is a lot more to it than that, but this is the extremely simplified veraion due to space restrictions and I am replying using my phone. Hope this may help..
