The moon, as it makes it's way around the zodiac, makes a connection to the different planets along the way. The connection, whether it's a conjunct, sextile, square, trine, quinqux, or an opposite, create a different emotion depending on what kind of aspect it is and which planet it aspects. This feeling it creates, is a collective mood, an overtone, of the day. Sometimes it lasts a day, or sometimes only a few hours. Every time that aspect changes, so does the mood, the collective feeling. Sometimes, it doesn't make any aspect at all, which we call a moon void of course. This creates it's own special feelings too. I've assigned a picture and a mood to each of these feelings and displayed them in the project called Mood of the Moon. I also decided to turn it into an oracle deck to complement The Serpent and the Peacock. Currently, the Mood of the Moon can be found on the the web at moodofthemoon.com, and on android app Libra Moon Inc (sorry it didn't get accepted to apple) and it is also part of the Lunar Affirmation App. . Some time in 2025 I do plan on making a stand alone app for just the Mood of the Moon
