Hecate's Day today, Ancestors Day/Deipnon tomorrow, Noumenia after that, then the Agathos Daimon after that. Four days of strict ritual and offerings ahead of me.
Hecate's Deipnon (Dark Moon) is about Purification of self and home. Clean, clean, clean; and take care of home affairs, like bills and restocking the pantry. Noumenia (New Moon) is about Renewal, and worshiping the household Deities. Agathos Daimon (Waxing Moon) is about Replenishing, and honoring the House Spirits, and asking for protection over home and family.
I'm going to add the making of a Kathiskos on the Deipnon this month. A Kathiskos is a jar containing mostly dry items from your pantry. Once made, you ask for protection over your food stores from Zeus Ktesios (Protector of Household Goods and Home Prosperity), for the month. Next Deipnon you dump the jar outside, and refill it on the Noumenia for the month.
This is just the tip of the iceberg of my monthly rituals. I asked for more ritual and structure in my faith, and I certainly got it when led to Hellenic Polytheism! :-)
Also on the Dark Moon, I honor the Ancestors', Spirits, and Guides.
Also on the New Moon, I honor Kuan Yin and make more Lotus Water.
The 6th, is Artemis' Day.
8th is Poseidon's Day.
Full Moon's I honor Sister Moon, Tara, Bear, The Madonna, Mary Magdalene, Ceres, Dionysus, Dibella....and I think that's it.
I'm pretty sure there's other monthly rituals for HP, but I'm not fully aware of them right now. I do have the Hellenimos Calendar saved in my bookmarks, but I want to get what I know of down first.
