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 14 signs this month, in order: Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio. It changes sign 13 times — roughly every two and a third days, though not evenly, because the Moon’s speed varies about twelve per cent over an orbit.
A lunar eclipse this month
The full moon on December 20 is a Total lunar eclipse, with 100% of the disc inside the Earth’s umbra at maximum, at Gemini. An eclipse can only fall on a full moon, because it needs the Moon exactly opposite the Sun and close to a node — which is also why they arrive in pairs a fortnight either side of a solar eclipse.
