What is a Birth Chart?
Visually a chart is a 360 degree wheel divided into 12 sections. Each section is named after the famous constellations or zodiac signs that we are all familiar with (i.e Aries, Leo, Gemini, …). Your planets are plotted onto the wheel to see which sign they fall into to. For example, to calculate your Sun sign we look at which zodiac constellation the Sun was sitting in at the time of your birth.
Astrologers interpret this map by looking at the interplay of all your astrological elements and based on the archetypes that each of the signs represent. Each planet can offer insight into your individual character and clarity about your soul’s avenues for growth and personal evolution.
What is a Synastry Chart?
Visually a synastry chart looks exactly like a birth chart – a 360 degree wheel divided into 12 sections. The only difference being that there are twice as many elements being charted. In a synastry chart, an aspect is the geometric relationship between the two sets of planets. An example of an aspect shape includes a square, trine, conjunction, and more. Each aspect shape produces a different meaning.
Synastry charts and composite charts are similar in that they both explore relationships. Synastry charts are used to examine relationships between two people or, more specifically, how they may effect each other individually. From that an astrologer can use the chart to interpret the character and dynamic of the relationship.
