All numbers in the occult are linked to different things. Once you understand their meanings you can apply them to everything in magick. Look up the symbolism in numbers and you'll find you answers.
Sunwise and moonwise, deosil and widdershins, clockwise and counterclockwise all depend on your culture/path and location (southern hemisphere verses northern hemisphere).
In Cherokee medicine, counterclockwise is used almost always. My circles are always drawn in a widdershins direction.
Widdershins in european magick is moon associated and only became known as a decreasing/banishing movement in modern times.
Modern witches use deosil for invoking and widdershins for banishing. In pendulum usage, most view clockwise as a positive answer and counterclockwise as a negative one.
In the southern hemisphere the natural rotation is reversed. Toilets flush counterclockwise! Lol
