Astrology CalendarMercury Retrograde 2027: The Exact Dates
Three windows in 2027, with stations to the minute and the degrees each one covers. Computed from an ephemeris, not copied, and dated so you can tell.
Moon Phases
Full Moon in Aries is a culmination: the point where holding your tongue stops being diplomacy. Every date for the next six years computed from the ephemeris, which ones are eclipses, and how to tell whether one is yours.

A full moon lands in each sign roughly once a year, because the Sun takes a year to go round and the lunar month fits into it about twelve and a half times. These are computed from the ephemeris, in US Eastern time.
| Date | Exact degree | Also an eclipse? |
|---|---|---|
| October 15, 2027 | 21°59' Aries | No |
| October 3, 2028 | 11°00' Aries | No |
| October 22, 2029 | 29°16' Aries | No |
| October 11, 2030 | 18°11' Aries | No |
| September 30, 2031 | 7°26' Aries | No |
The degree matters more than most pages admit. A lunation only means much for you personally if that degree is close to something in your own chart, within a few degrees. A full moon at 12 degrees of Aries is a significant week for somebody with a planet at 11 degrees of Aries and an ordinary one for everybody else.
At a full moon the Moon is exactly opposite the Sun, which is why it is fully lit and why it rises as the Sun sets. Astrologically that opposition is the whole meaning: two ends of an axis, both visible at once, which is why full moons have the reputation for bringing things to a head.
The sign tells you the subject. Aries is Fire, Cardinal, ruled by Mars, and its keyword is I am. So a full moon here puts the point where holding your tongue stops being diplomacy on the table.
| Moon in | Aries |
| Sun in | Libra |
| Element and mode | Fire, Cardinal |
| Ruled by | Mars |
| Good for | finish, decide or let go of something already underway |
| The Aries version | the point where holding your tongue stops being diplomacy |
A full moon is always an opposition, so it is never about one sign alone. The Moon in Aries wants i am; the Sun opposite in Libra wants i balance. Those two pull against each other and the full moon is the point where you can see both at once.
That is why full moons feel like a reveal rather than an event. Nothing new arrives. Something already running becomes impossible to keep ignoring, which is a different and usually more uncomfortable thing.
The sign is the same for everybody. The house it falls in is not, and that is what decides whether a lunation is about your job, your money or your marriage. On whole sign houses, which is the system this uses, it follows directly from your rising sign.
| Rising sign | House it lands in | So it is about |
|---|---|---|
| Aries | 1st | you, your body, how you come across |
| Taurus | 12th | rest, grief and what nobody sees |
| Gemini | 11th | friends, groups and hopes |
| Cancer | 10th | career and reputation |
| Leo | 9th | travel, study and belief |
| Virgo | 8th | shared money, intimacy and endings |
| Libra | 7th | partnership, marriage and open conflict |
| Scorpio | 6th | daily work, health and routine |
| Sagittarius | 5th | romance, children and creative work |
| Capricorn | 4th | home, family and property |
| Aquarius | 3rd | talking, learning, siblings, short trips |
| Pisces | 2nd | money you earn and what you own |
That table is the single most useful thing on this page. A full moon in Aries is a career event for one person and a money event for another, and which one it is for you is fixed by a birth time rather than by a birthday.
That depends on where Aries falls in your chart, which needs your birth time. The same full moon lands in your career house, your money house or your marriage house depending on what was rising when you were born. Here is how to find your birth time.
October 15, 2027, 9:47 AM ET, at 21°59' Aries.
Finish, decide or let go of something already underway. The Aries version: the point where holding your tongue stops being diplomacy.
In Libra, exactly opposite. That opposition is what makes the Moon look full.
Only loosely. It matters to you personally when its degree is within a few degrees of something in your own chart. Otherwise it is a date in a shared calendar.
