The Blue Moon Periods
There is always a lot of talk about the Blue Moon periods. This is a period when there are two Full Moons in one month. This is supposed to occur once every two years. At first, when friends would inquire about the Blue Moon, I would casually state that it was nothing more than two Full Moons in one month… PERIOD.
As I experienced the energies the events that occurred during a Blue Moon month, I realized that there was an excess of amplified lunar energies such as would be found in a Crisis Full Moon period. In May of 1988, I wrote an that I was trying to suppress “homicidal tendencies,” especially when anything would go wrong. Never again did I say that there was nothing to a Blue Moon period. So, with any Moon period, know that you are not crazy— it is the Lunar Phenomena. Know that there are dynamic forces in the cosmos hitting you and be assured that these feelings are normal.
In May 2007, the entire month of May seemed like Mercury was retrograde. If anything could go wrong, it did… but Mercury does not turn Retrograde until June 15! Because of the time zone differences, Europe will experience its Blue Moon month in June.
What is a Blue Moon? Full moons are separated by 29.5 day intervals— the moon’s Synodic Period. By counting out synodic intervals, and checking to see when a pair of full moons falls into a single 30- or 31-day month, we can easily and precisely figure out when the next blue moon is due: December 2009 and November 2010.
- The Lunar Synodic Period is the time between successive New Moons or 29.5 days.
- The Lunar Sidereal Period is the time it takes the Moon to complete one orbit around the Earth with respect to the stars or 27.3 days. The Sidereal Period of the moon is measured watching its motions against the background stars.
Why are they different?
While the Moon orbits the Earth, the Earth orbits the Sun. Start at New Moon: Sun-Moon-Earth aligned. It takes the Moon 27.3 days to complete 1 orbit around Earth with respect to the stars. In the meantime, the Earth has moved through 27.3 days of its orbit (about 27deg along its orbit). The Moon & Earth must move together for an extra 2.2 days to re-align with the Sun.

Hi Lynn,
I have heard if a person has a birthday during a hostile moon, the whole year will be difficult, is this true?
My birthday is March 13, during a full moon and another coming on the 26th.
Is this going to effect the year?
Thank you for your help.

Susan, in my almost 50 years of studying astrology, I have never hear the term Hostile Moon. I do not know what it is.
If a new or full moon occurs within a day of your birthday, you will have a major change within the coming year, connected to the House position of your Sun. This are often positive.
A young girl has this on her 3rd House Sun and she changed from public to private school. It is not a bad thing.

Hi!
Okay since you seem to me a reliable person in the astrological field I was wondering what it means to be born under a blue moon? I’m turning 19 Jan. 01 but my friend turns 19 on the 31st of December…. Does a blue moon affect her or my natal chart?

First, it would take extra time to see if someone was born under a Blue Moon. When I used to calculate charts by hand, it would be easier because I would be looking at the ephemeris but it never occurred to me to do this.
It is only possible when the Full Moon birth occurs at the very beginning of the month or the very end of the month…but I never bothered to take this into consideration so I have no observations.
If someone was born at the time of a Full Moon, their parents were often totally different. I suggest reading Betty Lundsted’s book on ASTROLOGICAL INSIGHTS INTO THE PERSONALITY. (www.astroamerica.com)
Some peole have told me that, because they were born on a Full Moon, they are more emotional during that time.
These December Full Moons are Crisis Full Moons so that there are often highly charged events occurring at the time. With an Eclipse, there are often national or internation events occurring – and we have had many of these.
For how this is affecting you, look at my article on the Crisis Lunations on this site.

Hello Lynn,
This is very interesting. I looked this up as soon as I learned that there was a Blue Moon this month. My period was about 6 days late and I have been absoultley psychotic- way more than the usual cycle this month! Any comments? Thanks!

Just as I said in #4, read the Crises Lunation article on this website. It is more relevant than the Blue Moon.

Hi Lynn,
I was born under a full moon in december – can you tell me what this blue moon would mean for me?
