Day by day
The four quarter instants are marked on the day they fall; every other day carries the interval it is in. Four of the eight phases are moments and four are stretches, which is the one thing most calendars leave out.

The Moon passes through 15 signs this month, in order: Capricorn, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces. It changes sign 14 times — roughly every two and a third days, though not evenly, because the Moon’s speed varies about twelve per cent over an orbit.
This month’s full moon is the Harvest Moon
The Harvest Moon is the full moon falling nearest the September equinox — a rule about the sky, not a slot in a month table. That is why it moves between September and October from year to year, and why a calendar that reads the name off a fixed twelve-row list gets it wrong in the years it lands in October.
