Surgery by the Moon

Surgery tips are to plan surgery based on:

1. No full Moon to avoid swelling

2. Lunar Cycle: waxing to add or waning to remove

3. Moon Signs

4.  Seasonal Weather

5. Holidays and Medical Staff

First of all, good feng shui! Organize your home, especially the room where you will rest and recovery after surgery, so that your environment is set up to help you heal when you return from the hospital. Feng Shui tips.

And prepare your food before your surgery. Have in the fridge or freezer your soups, bone broth, juices, or whatever food is best for your recovery. You have time to read, so here’s the link to my books

No Full Moon for Surgery!
Don’t know when the Moon is new or full? Stay current by following my LUNAR BLOG

The most important surgery tip is to avoid the full Moon! So no surgery on the day of the full Moon, or during the 3 days before, or the 2 days after the full Moon to avoid swelling, bruising, and complications. Like sap rising in a tree or the powerful ocean tides, fluids rise on the full Moon. Bruising and swelling is much greater on a full Moon. 

So look at the monthly calendar to block out 3 days before, the day of, and the 2 days after the full Moon.

A full Moon is when the Sun and Moon are opposite, and that can bring tension to the surface. There’s much data on how emergency rooms are more active during full Moons, more babies are born due to the pull of the Moon, and more. So avoid it all by remembering no surgery 3 days before, the day of, and 2 days after the full Moon. So block out those 6 days each month because they are not good for surgery. 

What about Mercury Retrograde?
Mercury retrograde is usually not a problem for surgery. Surgery is very routine, not highly mercurial. Surgeons are not making up new methods as they go. Mercury is retrograde for three weeks, three times a year.

If your surgery is during the three week Mercury retrograde, allow enough time to get to your surgery appointment, and plan to arrive early. And know the exact surgery location if it’s different from where you usually see your doctor. Anticipate that there could be a mercurial mix-up, such as incorrect billing.

Lunar Cycles
Once you know the 6 days to avoid near and on the full Moon, then does your surgery add to the body, remove from the body, or both?

Add during the Waxing Moon:
The waxing Moon is best to add to your body. The waxing Moon starts on a new Moon, and lasts for the next two weeks, building up to the full Moon.

Schedule operations that add on the new Moon, or during the next 9 days (or so) after the new Moon. Stop 3 days before the full Moon.

So the 9 days of the waxing Moon is the time for surgery to add (not remove) something to your body, like a new hip, heart valve, or a breast implant for a cancer survivor. 

Remove during the Waning Moon:
The waning Moon is best to remove from your body. The waning Moon starts the day after the full Moon and lasts for the next two weeks as the full Moon wanes down. This is the time for surgery to remove something from your body, such as a tumor. 

So schedule operations to remove starting 2 days after the full Moon until the next new Moon. People often confuse waxing and waning because when they think of waxing, they think of candle wax melting. But waxing is building up to the full Moon, not melting down after the full Moon. 

What if your surgery does both; removes from the body and adds to the body? Then both the waxing or waning Moon cycles are fine. Just be sure to avoid the full Moon, and the 3 days before and the 2 days after the full Moon.


zodiac-man-1413-16-2Moon Signs

So avoid the full Moon, and figure out if you’re adding to or removing from your body. Then avoid the Moon sign that rules that body part. — from Aries the head down to Pisces the feet.

Aries rules the head, including face, brain, and eyes.

Taurus rules the throat, including neck, vocal chords, and thyroid gland.

Gemini rules the lungs, including the shoulders, arms, hands, and nervous system.

Cancer rules the breasts.

Leo rules the heart, and upper back.

Virgo rules digestion, intestines, and spleen.

Libra rules the kidneys, lumbar region, and buttocks.

Scorpio rules the sex organs and bowels.

Sagittarius rules the thighs, hips, and sciatic nerve.

Capricorn rules skin, teeth, and bones including the skeletal system.

Aquarius rules the ankles and circulatory system.

Pisces rules the feet including toes, lymphatic system, and adipose tissue.

The Moon changes signs every two to three days. For examples, avoid breast surgery during the Moon in Cancer because Cancer rules the breasts, avoid an abortion during Moon in Scorpio because Scorpio rules sex organs, and avoid knee surgery during Moon in Capricorn because Capricorn rules skin, teeth, and bones.

I wondered what if the rulership Moon sign strengthened surgery for that body part, not something to avoid. So I deliberately schedule a tooth implant during a Capricorn Moon. Plus I had to travel to the implant place so I thought that a Capricorn Moon would help to stay practical and focused. But it was not smooth sailing, to this day the implant is not right, and from now on I make a point to avoid the rulership sign!


The Four Seasons

Spring, Summer, Autumn – not Winter cold. You’ve avoided the full Moon days, know the lunar cycle to add to or remove from the body, and understand the Moon sign. Next when you are selecting your surgery date, consider the season! Of course, if there is an emergency or you cannot wait for better weather, then schedule right away to take care of your health. 

For most people, if you have a choice about when to schedule surgery, chose a time in spring, summer, or autumn. Avoid the cold and flu season of winter when hospital staff could be sick, people are distracted by the holidays, and when your own immune system is weaken by harsh weather. It’s much easier to heal in mild weather. If you have any sort of sensitivity to loss of light in winter, it will be easier to keep your spirits up when there is more light outside. Keeping your spirits up

A woman in Holland emailed me that she prefers surgery in winter when it’s comfortable to stay in bed, the long nights are better for deep sleep and rest, and it’s easier to take a work break during the holidays. So if winter works for you, then schedule during the winter months. 


Holidays and Medical Staff

Medical staff have a busy life too! Monday morning after a holiday weekend is not the best time to schedule your surgery. If you schedule on the day after people return to work after a holiday weekend, or any event with lots of eating and drinking such as Superbowl Sunday, anticipate that hospital staff probably won’t be rested.

On a Friday afternoon, most people who work Monday through Friday want to be out the door after lunchtime. So schedule your surgery for Friday morning, not late afternoon before the weekend.

Avoid scheduling surgery on dates that are on or too close to a holiday. For examples, the couple of days before Thanksgiving or Christmas, few people have their mind on work. Avoid surgery on Halloween when people come to work in costume and want to have fun. On or the day after St. Paddy’s Day, or April Fools Day, can be problematic because workers could be tired from celebratory activities.

So schedule a day and time when hospital staff are in their routine to avoid problems.


Earth, Air, Water, and Fire

All signs are good, they just offer different energy.
I feel that favorable lunar signs for surgery are Earth signs Virgo, Capricorn and Taurus. These Earth signs are grounding operations or change of the physical body. They are the best signs for good food, health focus, healing, and stamina.

My favorite Moon sign for anything medical is Virgo when people are more focused on details — unless the medical work is for digestion, stomach, or spleen because that part of the body is ruled by Virgo. 

Moon in one of the Air signs Gemini, Libra, and Aquarius are especially good for technology and modern medical procedures.

Moon in one of the Water signs Pisces, Cancer, and Scorpio events can flow and there can be good connections with healers, but people can be more emotional.

Fire sign Moons Sagittarius, Aries, and Leo are dynamic and focus on accomplishment. I recently did dental work (a new crown) on a Sagittarius Moon because my Moon is in Sagittarius. The dental work went quickly, and we stayed on target without distractions.

Still, I prefer Earth sign Moons for surgery. For examples, if you have a choice between an Aries Moon or a Taurus Moon on the following day, schedule for the Taurus Moon. Avoid scheduling on a Leo Moon if you can wait a day or two for the Virgo Moon.

If you can select your surgery date when the Moon is not void of course, then do so. Void of course means the Moon is changing to the next sign. But so much surgery is routine that the void Moon is usually not a strong influence because the doctor is not innovating new methods, and is not practicing on you!


Mutable, Cardinal, and Fixed Modes

Mutable, or changeable, astrology signs are Virgo (Earth), Gemini (Air), Pisces (Water), and Sagittarius (Fire).

Cardinal, or active, astrology signs are Capricorn (Earth), Libra (Air), Cancer (Water), and Aries (Fire).

Fixed, or solid, astrology signs are Taurus (Earth), Aquarius (Air), Scorpio (Water), and Leo (Fire).

Mutable Moon signs are fast and easy. Cardinal Moon signs are good for accomplishments. Fixed Moon signs are slow and steady.
All modalities are good, they just bring different energy. I like quick mutable energy, but liking cardinal energy probably makes the most sense for surgery, and I understand how people would like fixed Moon signs for stability. Go with the Moon sign you like, but just be sure that the Moon sign does not rule the body part that needs surgery. 



Egg in the light. Bleed in the dark.

Ovulate on the full Moon! Figure out when you menstruate and get your body in sync to produce your egg when the Moon is full. If you are trying to get pregnant, ovulation is the time you want . 

Menstruate during the dark Moon, preferably during the balsamic Moon that’s the final two or three days of the lunar cycle. This is the quiet time to rest, release your blood, and honor your body.

Then you can plan travel and other stimulating events on or near the full Moon. Plan quiet, restful time during the final days of the lunar cycle during your menstruation. And yes, men are influenced by lunar cycles too.


Water sign Full MoonENTERTAIN, WED, and CELEBRATE under the full Moon light

Celebrations, weddings, and parties are best on the full Moon, or as close to the full Moon as possible!

Planning an art opening or family get together? The best attendance will be on or close to a full Moon. An event held on a dark Moon at the end of the lunar cycle will attract fewer people.

Seasons can influence attendance. An event close to summer solstice is easier for most people to attend than the same event held close to winter solstice 



Avoiding the full Moon avoids a lot of strong energy, but flying on a full Moon is beautiful to see in the sky below the plane.

So decide what Moon phases you want to experience when you get to your destination. For a two-week vacation, I recommend to fly a week before the full Moon, be there for the full Moon, then fly out one week after the full Moon.

Wishing you good luck as you follow lunar cycles!




  1. Thankyou for all of your Moon Wisdom! As a Moon~in~Cancer Girl, I’m definitely always my happiest, most creative, and most energized when the Moon is Full! I love your new mobile site! Love, Jennifer

    • Thanks Jennifer. So nice to hear from you. Yes, we Water-sign sensitives are so influenced by Mother Moon. And keep reading your tarot cards! You’ve got it.

  2. hello…great article. I am planning a surgery to remove cartilage from my hip joint and the doc will then replace the cartilage with new tissue either from another part of my leg or even possibly from a cadaver. since its a remove and an add surgery what do you suggest is a best moon time. still waxing?
    thank u so much!

    • Dear Christy,
      Yes, do this surgery on the WAXING MOON if you have a choice about it. You want the new cartilage to bond and settle in place, getting stronger on the full Moon. Massage it, sing to it, and make it feel at home in the new location of your body. On a dark waxing Moon new cartilage might not take or need to be replaced. And don’t be freaked out by tissue from a cadaver. It’s recycling and reusing, very good ecological management. Good luck!

  3. I’m having an operation to explore my abdomen, just to see what’s going on. I’m not having anything removed or added into my body, the surgeon is just gonna look inside. I’m having this 3 days before the full moon as this is urgent. Do you think this is ok? I have sextiles between mercury and jupiter and mars that day, which I hear should indicate successful operations. I also have pluto trine sun in my solar return, with lots of eighth house action (the house of surgery) and lots of positive jupiter transits (to my natal chart) happening around the same time. Do you think this will be ok, as it’s just exploratory surgery, as opposed to more complicated surgery? Thanks for reading and I really enjoy reading your site 🙂

    • Dear friend,
      Since this is urgent, go ahead and take care of your health. Great that you are having such good transits at this time.
      To be very safe, plan for swelling and discomfort — even if you are fine. Take it very easy after the exam, and take very good care of yourself during the full Moon. So no big plans for a few days, and a Taurus full Moon on a double Pig day is perfect for relaxing, healing, and eating well.
      From now on, when you have a choice about surgery dates be sure to avoid full Moons when possible.
      Good luck,

  4. Hi Susan,
    I now have MAJOR, life changing surgery that I’m about to schedule soon.
    I know it is currently mercury retrograde season, so the whole of February is out – However, they’ve said the surgeons (who are VERY in demand) will only be available to schedule it for March? Another problem is, the surgeons are only available on a Saturday!
    So if you could advise me on a day to pick because I’m feeling really lost right about now.
    It has to be in March and on a Saturday, but I’m so confused about which one to choose as I remember you said to avoid the Full Moon, and to be as close to a New Moon as possible, etc.
    If it helps, I’m having this major surgery on my uterus area.
    If you could advise me on the best Saturday in March to go for I’d be so grateful, as I’m feeling really alone right now and have to make this huge decision all by myself.
    I just really don’t want to make a mistake by picking the wrong date because this is really major surgery.
    Thanks so much for reading xxx

    • Should have also made clear: I’m having major surgery, during which I will actually have my uterus removed. Thank you xx

    • Avoid the full Moon weekend of March 15 & 16. Sat Mar 22 is the best. Good luck!

  5. Dear Susan, thanks for such an awesome site that is so helpful and informative. I hope to achieve my dreams of being a successful astrologer like you one day and you’re a great inspiration. Since I was young I’ve been troubled by health problems but hope to resolve them soon by surgery which has been scheduled for April 12th. This date is definitely when I will be having it done, does it look ok to you? This surgery is extremely urgent and cannot be postponed any longer. Thanks a bunch! -Hope xoxo

    • Dear Hope,
      Thank you for your kind letter. Your surgery date is EXCELLENT! On a nice dark balsamic Moon.
      You can rest & heal that weekend, and into the new Moon eclipse on Tuesday.
      Be sure to lay low & take care. Don’t jump out of bed too soon in a Dragon month & Wood Horse year.
      Good luck!

  6. I plan to have hip replacement surgery but am concerned that it be at a good time. What dates in July or August would be the best?
    For the year 2014.

    • Avoid close to the full Moon on July 12, and avoid close to the full Moon on Aug 10.
      July 1 – 4 is good, then after the 15th to the end of the month.
      Aug 1 – 6 is good, then Aug 13 to the rest of the month except for Aug 30 and 31.

      Good luck and be sure to allow yourself enough time to heal.
      Do not hop out of bed too soon in this Horse year then and reinjure your hip.

      For more specific info, we should schedule a consultation.
      Good luck.

  7. My aunt is scheduled get surgery on March 25th. She is fixing a deviated septum, nose job and a surgical peel of her face. The things I’ve read lead me to believe this is not a good date. Should she reschedule? Or if it must be that day how do we counteract the date not being ideal?
    Please advise

    • Dear Christie,

      This date is fine. I do not know why you think it is not good. It is 5 days after the new Moon, well before the full Moon on April 4.

      Just stay out of the sun after her face is peeled. In general, schedule skin peels in winter not during the hot days of summer.

      Good luck!

  8. My younger brother had met with an Accident in March 2013..he had a multiple compound fracture in his right leg and a titanium rod was placed inside his Tibia bone ( the bone beneath the knee) . He has to remove the rod and we were thinking of 30th March. Kindly advise when I could schedule the Surgery. I would be really thankful as I am worried for him. He’s just two years younger to me but he’s like my baby. Thank you and please advise !!

  9. I should get removed my uterus which day is good in Feb16, pls reply me immediately as it is most urgent

  10. Dear susan, My daughter’s Adenoid removal surgery is planned thsi month.Please suggest suitable date for the same.
    Thanks & regards

    • Dear Deepa,
      Surgery to remove something from the body is best during the waning Moon.
      In April 2016, the waning lunar cycle begins after the full Moon on April 22.
      Friday April 23 is too close to the full Moon. And it’s Earth Day when people are not fully focused on work.
      Good days are Mon – Fri during the week of April 25 – 29.
      Good luck,

  11. Hi, Urgent I am scheduled for a sinus surgery: polyp removal & deviated septum, Friday 4/22/2016 @ 11:30am. Should I reschedule?

  12. Dear Susan,
    Would you please advise me if March 17 at 8am is a good day for a selective surgery?
    Thanks a bunch and best regards

    • Dear Peggy,
      March 17 is far enough from the full Moon that was on March 10, but it is St. Patrick’s day so people will be partying, or wanting to get off work to go party!
      Good you are scheduled for 1st thing in the morning before people are off to celebrate, and celebration could start at lunch.
      If you are not released right after your surgery, be aware that workers could be hung over or sick the next day, and make errors when they are attending to you on March 18.
      It’s best to avoid all holidays.
      But in general, 8 am on March 17 is good.
      Good luck,

  13. I’m trying to figure out what is a better date for surgery july11,2017 or August 15, 2017. Also can u give me pointer on how to figure out what to look for in determing the best dates

  14. Hi, I’m scheduled to have a total hip replacement on Aug 28,2017 and I just realized it is during the Mercury Retrograde Aug 12-Sept 5 2017…I thought the good news was that it was not during a Sagittarius moon and that it was within the 9 days following a new moon. A waxing moon is best right? Oh my goodness, it is hard to get it right, please help. I happen to be a double Libra with a Sagittarius Moon born 9/26/1960 7:49am Queens NY
    Thank you!!

  15. I am having hip replacement next fall 2019 and I can try to choose the best date. The New Moon is Saturday September 28th so it is best to have the surgery Monday 9-30 or October 1st? I can request. My BD is 02/02/1947 Aquarius with Moon in Cancer, Pisces rising.Thanks for advice.

  16. Dear Susan, I will be having a breast reduction procedure on April 21st 2020. The moon will be in Aries which means that breasts should be fine. The only problem is that the Doctor would also like to operate on my eyes to perfect the surgery done this year. A very minor procedure but do you see any problems arising from having both procedures done at the same time. Thank you so much for your advice 🙂

  17. Hello Susan,
    I’m having one Impacted wisdom tooth removed two days following a new moon. Also the moon is in Aries on evening of my surgery date. Is that ok or should I schedule another day?
