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: Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo. 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 Hunter's Moon
The Hunter’s Moon is simply the full moon after the Harvest Moon, and the Harvest Moon is the one nearest the September equinox. Both are fixed to the equinox rather than to a month, so which month carries them moves from year to year.
