Hey Alex, heres the answer for days of the week. It all started with Caesar creating the calendar we have now which is approximately like a sphere as it spans 360 degree despite the leap year and it rotates in your mind. You have the 7 days where 7 is a god number and each day represents a god day for example monday means moon day, saturday saturns day, thursday or thorsday, sunday or sun's day and so on. Theres also a reason for 52 weeks of the years but I cant remember at the moment but 12 months in the year is significance as 12 much like the zodiac, disciplines, and so forth is incomplete in comparison to a divinity number like 13. thus such oppossor see themselves as rulers over 12 so they become the divinity.
