Astrologers traditionally also consider the phase of the moon at the time of birth in interpreting its effects on the individual.
First quarter (new)
Astrologers say a person born in the first phase of the moon will have an underlying sense of youthful enthusiasm and optimism, a touch of the zodiac sign Aries in their nature. They will probably prefer to take the initiative, especially in romance, and will be ready to look for new interests in life, new people and new ideas. The person will see how things can be improved and can spur others to action, before leaving them to finish the project. They will probably get off to an early start in life and be quite successful when young, though other factors in the chart will indicate whether this success is lasting. They need to guard against selfishness and taking others by surprise with over quick and hasty reactions.
Second quarter (waxing)
Astrologers say a person born in the second quarter will be ambitious and sociable, with an underlying touch of the zodiac signs Cancer and Leo in their nature. The person will be locked into their goals and have a strong need to create something which will be remembered by others. They will have a charismatic personality that draws others to them, but may instinctively use others for their own ends, rather than help them. They prefer a career where they are out in front and have attention and status. They also need a place of their own to express their personality, either their home or workplace. The person should achieve considerable success when young, but other factors in the chart will indicate whether that status is maintained. The person will be slow to anger, but formidable when aroused, and hates to be hurried or presented with a fait accompli. However, they won't mind doing this to others if it tips the odds in their favour.
Third quarter (full)
Astrologers say a person born in the third quarter will be sensitive to the needs of others and expects others to be sensitive to their own needs. There is an underlying sense of watchfulness reminiscent of the zodiac signs Libra and Scorpio. The person will need friendships, colleagues and relationships, and will relate well to others. They will either be drawn to highly successful people and help them achieve their goals, or else achieve success themselves with the help of others. There is a tension and nervousness at play which can lead to a short attention span and a constant search for new people and experiences, and sex will play some kind of transformative role in their life. The most successful time of life will be in the middle years.
Fourth quarter (waning)
Astrologers say a person born in the fourth quarter will have an underlying feeling of the zodiac signs Capricorn and Pisces. They will finish the projects that others start, and reorganize and sort out the problems left by others. They will often have clairvoyant insight and follow hunches rather than be logical. The person can be too sensitive and become upset by the demands of others, and can also be too inclined to sit back and let things happen. They will work best in groups and are not materialistic, but they do need job satisfaction. They may be slow to grow up, but are likely to go through some kind of metamorphosis later in life and achieve success in something unusual and completely individual.
