Astrology 101: These Zodiac Charts Reveal The Truth About You & Your Relationships

Love hearing from The Astrotwins? Check out Ophi’s appearance on our new podcast, where she offers insight on crucial topics like how to handle Mercury retrograde, what to do if you’re in a relationship that’s astrologically incompatible, and the rituals we should all be prioritizing when there’s a new or full moon.

An astrology birth chart—also called an astrology natal chart—is a map of where all the planets were in their journey around the Sun (from our vantage point on Earth) at the exact moment you were born. An astrology chart reading can reveal your strengths and weaknesses, your opportunities for soul growth, and the best timing for your most important moves.

To calculate your astrology birth chart, you’ll need your time, date, and place of birth. Some people don’t know their birth time. If you can’t find it on your birth certificate, you can try contacting the Vital Records office in your state or area of birth. And if that still doesn’t work, make as close of an estimate as you can or enter 12:00 noon.

Compatibility Astrology Charts: In addition to the astrology birth chart, you can do an astrology compatibility chart to see how you’ll get along with other people. You can cast two types of compatibility charts. A synastry chart compares and contrasts the planets in your chart and the other person’s. A composite chart averages out your two charts using a "midpoint method." It creates a single, blended chart that reveals the essence of your relationship. A composite chart treats your relationship as if it was its own entity or a third "person" (which in many ways is true!).

Astrology Charts for Planning Events: You can do charts for people and also for events. Just put in the time, date, and location of the event in question, and you can cast an astrology chart for it. For example, if you’re planning a party or a big pitch meeting, you can enter the time, date, and location to see how the stars align. Want to know what’s happening right now? Do today’s astrology chart by simply entering today’s date instead of your birth details. Wondering what the year ahead holds? Check out an annual forecast chart that maps out the next 12 months.

At Astrostyle, we work with the Western astrology system, which dates back thousands of years. Humans have tracked the movement of the heavens since civilization dawned. As far back as 6000 B.C. the Sumerians noted the journeys of planets and stars. Around 3300 B.C. the Babylonians (also known as the Chaldeans) began expanding upon what the Sumerians started, developing the first astrological system over thousands of years. They created the zodiac wheel that we use today (with planets and houses) around 700 B.C. The oldest known horoscope chart is believed to date to 409 B.C.
