What is a Birth Chart?
A birth chart, also known as an astrological chart or natal chart, is a unique cosmic snapshot of the sky at the exact moment and place of your birth. It maps your personality, natural talents, and the themes that will shape your life.
The chart includes the positions of all planets (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto), the ascendant (rising sign), and the 12 astrological houses. Each of these elements carries specific meaning and influence over different aspects of your life. At Vrachka, we help you read and understand what your chart reveals.
How Does the Calculator Work?
Vrachka's system uses Swiss Ephemeris — the most accurate astronomical library for calculating planetary positions, used by professional astrologers worldwide. The process includes:
- Astronomical calculations - Precise calculation of all planetary positions for the date, time, and place of birth
- House calculation - Determining the 12 astrological houses and the ascendant based on geographical latitude and longitude
- Aspect analysis - Identifying all significant angles between planets (trines, squares, conjunctions, etc.)
- Expert Interpretation - Generating a detailed psychological profile and life recommendations in English
The result is a detailed astrological analysis — written in plain English, no astrology jargon required.

Frequently Asked Questions
What is a birth chart?
A birth chart (or natal chart) is a cosmic snapshot of the sky at the exact moment and place of your birth. It shows the positions of all planets, the sun, the moon, and the astrological houses that influence your personality, talents, and life path.
Why do I need my exact time of birth?
The exact time of birth is critical for calculating the ascendant (rising sign) and the positions of the 12 astrological houses. These elements change every 2 hours, so even a small error can significantly change the interpretation.
What does the expert interpretation include?
Our system analyzes all elements of your birth chart — planet positions, aspects between them, houses, and signs. It generates a detailed analysis covering your personality, strengths, and challenges — plus career guidance and relationship insights.
How accurate is the birth chart?
We use Swiss Ephemeris — the professional standard in astrology software, based on JPL data, accurate to better than 0.001°. The interpretation is generated from the calculated positions, aspects, and houses.
What is an ascendant?
The ascendant (rising sign) is the zodiac sign that was rising on the eastern horizon at the moment of your birth. It represents the face you present to the world — how others perceive you before they get to know you.
Can I create a birth chart for someone else?
Yes! You can create an unlimited number of birth charts completely free -- for yourself, a partner, children, or friends. Simply enter their exact birth data.
What do the astrological houses mean?
The 12 astrological houses represent different areas of life -- personality, finances, communication, home, creativity, health, partnerships, career, and more. The planets in these houses show where your energy is focused.
Is the birth chart calculation completely free?
Yes! The basic birth chart calculation is completely free — it includes the full chart graphic, positions of all planets, ascendant, and houses, plus an expert interpretation. For a more in-depth analysis, we also offer a premium report.
