Moon phase
More than half and swelling — the least romantic phase, and the one where the work actually gets finished.
These are associations the community holds, not settled fact — the more a reading is shared, the bolder it sits.
Gibbous comes from the Latin for humped, which is a fair description of a moon that is more than half lit but not yet round. This is the stretch between first quarter and full, about seven and a half days, and it is up through most of the evening — rising in the afternoon, setting well after midnight. It is bright enough by the end to read a headline by on a clear night.
Almost nobody names a working after this phase, and that is a small injustice. It is the part of the cycle that corresponds to the least interesting portion of any project: the thing is committed to, the excitement has gone, and what remains is adjusting, correcting and grinding it towards done. Traditions that talk about lunar timing at all tend to fold it into the general waxing rule.
So the practice is plain. Refine, tidy, feed the thing that is nearly there, and fix what you already know is wrong with it. Practitioners who keep a lunar diary usually find this is where the honest entries are.
Readings practitioners have offered, ordered by how many recognise them. Take what serves, leave the rest.
Carried forward
James Frazer, The Golden Bough (1890)
Frazer treats moon-timed farming as a clean case of homeopathic magic: what grows in the sky is expected to make things grow on the ground, so seed goes in with a swelling moon. He is unpersuaded by the physics and impressed by how far the same rule travels.
Credit what you carry. Much of this comes from living traditions, and some of it from traditions that are closed — held by particular peoples and not offered for general use. Where you know whose practice a reading came from, name them; where you don't, say that too.
