Electing a date for a surgery or other medical procedure
This is a step by step guide to how I pick good surgery dates— or at least avoid bad ones. It’s based largely on Eileen Naumann’s the Planets and Operations, but I have added a bit, repackaged the info and presented it in a way that reflects the thought process I use.
If you want my help picking a surgery or medical appointment for yourself or a loved one, please read about this service and submit your information. The fee is reasonable, and I may offer a fee reduction or waiver if you cannot pay.
This is not beginner level astrology. If you aren’t comfortable working with astrology at this level, please don’t try to slog your way through this guide. Submit your information and let me help you. I have been doing this for several years, and I am happy to help.
What you’ll need
- A good astrological calendar that gives you dates and times for transits of the Moon and planets, and Moon v/c information (I suggest the Celestial Guide calendars from Quicksilver Productions, if you’re in the United States.)
- A transit list for the patient including transits of and to the personal planets and the outer planets. You can include Moon transits here if you want. I usually omit them from the list and eyeball them when I have found a date that looks good.
- A natal chart for the patient.
- (optional) a couple of highlighters
You can look at every possible calendar day if you want, but be aware that surgeons tend to have tight scheduling limitations. It is far easier to start with the surgeon’s availability and consider only those days that you know have open appointments.
What you’re looking for
A day that meets two criteria: (1) clear skies, and (2) good transits— or at least a lack of bad transits— to your chart.
The most important planets to consider are Mercury (which rules doctors) and Mars (which rules surgery). Avoid surgery when either of these planets is under stress, either in the sky or in your chart. Look for days when they make easy aspects (trines and sextiles) with natal and transiting planets. If the surgery is cosmetic, look for a date when Venus is well placed.
Also important are the Sun (patient’s vitality), the Moon, and the planet that is associated with the part of the body being cut.
Before I begin, I go over my transit list and highlight transits from outer planets with my pink highlighter, Mars transits with my yellow highlighter. It makes it easier to read the most important transits.
I also highlight planet transits on my calendar, to distinguish them from Moon transits. There are many more Moon transits than planet transits, and this helps make the planet transits more obvious. I also highlight Moon v/c days in a different color, so I won’t miss them. If there’s an outer planet transit (like Saturn opposite Uranus) coming up, its energy has a stronger impact and longer duration. I’ll circle it so I won’t forget it’s there.
Be aware of the time frame for transits. Moon transits last about 2 hours. Sun, Mercury and Venus transits last about a day. Mars transits last 2 days. Outer planet transits last 2-4 weeks. Transits can last longer if the planet is stationary or close to it. Transits are strongest just before they are exact, and the energy tends to dissipate pretty quickly afterward.
Also check the 3-5 days following the surgery, the most critical dates for recovery. Occasionally I’ll see a suitable date for surgery with something rough coming up afterward. In that case, I’ll point out the upcoming rough energy and advise the client to take it easy.
- The week before the New Moon. Do this, and you are halfway there. Waning Moon, at least 5 days past full is best.
- Trines and sextiles from transiting Mars. Mars trine or sextile the Sun, Moon, Ascendant, Saturn, or Pluto is especially good. But any “kiss” (favorable transit) from Mars is good and supports a positive outcome. Remember we are concerned with transits to the patient’s birth chart and to other transiting planets in the sky. So if, for example, transiting Mars is trine the patient’s Sun but square transiting Saturn, look for another day.
- Trines and sextiles to and from Mercury. Mercury governs the information, details, logistics, and minute procedures of the operation.
- Mercury or Mars conjunct Jupiter. Mercury or Mars conjunct or opposite Venus, Jupiter or each other may work if there is support from other planets or the Moon. But not if there’s a planet or the Moon squaring it. Mars conjunct Mars is good. Avoid Mars opposite Mars.
- Favorable transits from outer planets (Jupiter-Pluto) to patient’s natal chart
- Favorable transits from the Moon to other transiting planets, especially Sun, Mercury, Mars, Saturn, Uranus, Neptune, Pluto. Venus isn’t that important unless it’s a cosmetic procedure.
Nice if you can get it
- Moon in a fixed sign— Taurus, Leo, Scorpio, Aquarius
- The Moon’s final aspect before going void of course being favorable
- (for cosmetic procedures) Venus in Taurus, Cancer, Libra, or Pisces
- Avoid surgery within 3-5 days of the full Moon. Avoid the waxing Moon. Just a few days after the new Moon is ok, but the closer to full, the more potential for problems.
- Mars squares. Mars under stress signals hasty action, accidents, pain, inflammation, bleeding, arguments, anger, fighting. Basically all the stuff you don’t want around you when you’re having surgery. I do not recommend surgery when there is a square from transiting Mars or to natal Mars. (Venus square Mars could go under “avoid if you can”, if it’s not a cosmetic surgery, if there’s no other trouble around it, and if there is something good or very good to offset it.)
- Mars conjunct or opposite Sun, Moon, Saturn, Uranus, Neptune, Pluto. Mars conjunct or opposite Mercury or Venus may work if there is support from other planets or the Moon. If there’s another squaring planet, probably not.
- Mercury or Sun square or opposite Mars, Saturn, Uranus, Neptune, Pluto
- Mars retrograde
- Mercury retrograde
- Unfavorable transits from the Moon to to other transiting planets, especially Sun, Mercury, Mars, Saturn, Uranus, Neptune, Pluto. Venus isn’t that important unless it’s a cosmetic procedure.
- Unfavorable transits to the planet that rules the part of the body undergoing surgery. Moon for stomach and breasts, Mercury for lungs and hands, Jupiter for liver, Sun for the heart, etc.
Avoid if you can
- Moon in the sign that rules the part of the body being operated on. (Every sign corresponds to a part of the body. For example Aries is associated with the head. Therefore, Moon in Aries is not the time to operate on the ears, jaw, brain, eyes, head, or face.)
- Moon void of course
- Moon in the sign opposite your Sun sign
- Mars in the sign opposite your Mars sign
- Moon in a mutable sign— Gemini, Virgo, Sagittarius, Pisces.
- Unfavorable transits from outer planets to patient’s natal chart.
- The Moon’s final aspect before going void of course being unfavorable
- (for cosmetic procedures) Venus in Aries, Virgo, or Scorpio
About the Scorpio Moon. I have read in more than one place that the Scorpio Moon is to be avoided. I don’t know where that came from. If someone has some research to back up that claim, I would be happy to take a look. But until I see it, I will continue to maintain that Scorpio is one of the better Moon signs for surgery, as it is a fixed sign. In my own research, I have seen plenty of evidence of the power of Mars and Mercury transits, confirmation of potential for problems around the full Moon, but I have never seen a problem with the Scorpio Moon. (unless the Moon was nearly full or accompanied by a bad Mars or Mercury transit!) Do with that information what you will.
