Although, to answer one question:

“How do I figure out the planetary hours and days?”

In the past, you’d have calculated the planetary hours with a pen and paper based on the time of sunrise (Jason Miller discusses how to do so in Advanced Planetary Magic). But that’s tedious. If you visit Lunarium, and feed them the relevant information on your location (the default is London, England, so you’ll probably change it), then it’ll calculate the hours for you. Additionally, there’s an “Hours” app (I believe put out by the same folks) which will calculate it for you on your cellphone (iPhone and Android).
