Astrology and the natal chart

Astrology is the oldest way people have linked the sky and fate. The natal chart is a “photograph” of the sky at the moment of your birth.

Where astrology came from

It all began in ancient Mesopotamia (Babylon) more than three thousand years ago. Priests watched the sky and wrote down omens — the famous series of tablets “Enuma Anu Enlil” linked the movement of the planets with events in the kingdom. It was the Babylonians who, around the 5th century BC, divided the Sun’s path into 12 zodiac signs of 30° each.

The real revolution happened in Hellenistic Egypt, in Alexandria (around the 2nd–1st centuries BC). Here Babylonian observation met the Egyptian tradition and Greek philosophy — and horoscopic (natal) astrology was born: with the Ascendant, houses and a birth chart for a specific person. In the 2nd century AD Claudius Ptolemy systematized this knowledge in the “Tetrabiblos,” which became the foundation for centuries.

“As above, so below” — an ancient principle linking the movement of the heavens and human life.

Through the Islamic Golden Age the knowledge returned to Europe and flourished in the Renaissance. And in the late 19th–20th centuries psychological astrology appeared (Alan Leo, the influence of Carl Jung’s ideas, Dane Rudhyar) — it looks at the chart not as a verdict but as a map of personality and growth.

Key dates

What a natal chart is made of

What each house is responsible for

Twelve houses are twelve areas of life, from looks and money to career, friends and life behind closed doors. Each house has its own page: the classical and modern meaning, how to read it in your chart and how to check the description on yourself.

All twelve houses: what they are, which house system the site uses and how to check that the houses are calculated for your time →

The twelve zodiac signs

What a sign means for the Sun, the Moon and the Ascendant, the Sun’s dates in the sign by year, where traditions differ and how to check the description on yourself.

All signs: dates by year, elements and modalities, rulers and dignities →

The Ascendant in the twelve signs

Which sign was rising at the minute of birth: manner and first impression, the Descendant and the ruler, how many minutes the sign stays on the horizon in Moscow, St. Petersburg and Krasnodar. The Ascendant calculator also shows what you get if your birth time is off by 15 or 30 minutes.

The ten planets

What each planet means, how to read it in a sign and in a house, what a retrograde planet is and why the sign of Uranus, Neptune and Pluto is shared by a whole generation.

All planets: personal, social and outer, retrograde motion →

The five aspects

The angle between two planets tells how two sides of character are linked: they switch on together, nudge each other, get in each other’s way, help each other out or swing like a pendulum. How many aspects a person has and which of them are shared by a whole birth year — with numbers.

All aspects: orbs, how many there are in a chart and which ones mark the year, not the person →

The sky calendar: retrograde planets — when Mercury, Venus and Mars go backward, and Moon phases — new and full moons to the minute, Moscow time. Life cycles: Saturn Return — exact dates from your date of birth. The year from one birthday to the next — Solar Return: a chart for the moment the Sun returns, for the city where you spend your birthday.

In what order to read all this

Beginners usually drown in details: ten planets, twelve signs, twelve houses, dozens of aspects. Yet the order is simple, and you don’t need to memorize everything at once.

First — three points: the Sun, the Moon and the Ascendant. The Sun is about where a person grows and what matters to them; the Moon — how they feel and what calms them; the Ascendant — how they come across at a first meeting. These three alone are enough for the chart to stop being faceless.

Then — the elements: what the chart has a lot of, and what it lacks entirely. A chart without water and a chart where water is almost everything are two very different people, and you can see it at a glance. Then — the houses: which areas of life the planets fell into. And only last — the aspects, the angles between planets: they explain why you feel pulled in different directions inside.

Why the time of birth matters more than it seems

The Sun passes through a sign in a month, the Moon in two and a half days. But the Ascendant changes every two hours, and the whole grid of houses turns with it. So a date without a time gives the right planets in signs but no houses — that is, half the chart.

If you don’t know the time, use noon: the planets, the elements and most aspects will stay correct. We’ll warn you separately when the imprecision really affects the conclusions — for example, when the Ascendant falls right at the edge of a sign. We don’t get away with a general disclaimer like “the calculation may be inaccurate”: people simply scroll past it.

The place of birth is simpler than people think. We measured it: two points 195 km apart in the same time zone give an Ascendant that differs by one and a half degrees — and the sign of the Ascendant changes from such a shift in roughly five cases out of a hundred. What matters is the time zone, not the kilometers.

What a natal chart doesn’t do

It doesn’t predict events or name dates. It doesn’t make diagnoses — neither medical nor psychological. And it doesn’t pass verdicts like “this profession isn’t for you”: the chart describes how you’re built, not your ceiling.

It’s most useful where you already know something about yourself but can’t put it into words. The chart gives you the words — and with them it becomes easier to come to terms both with yourself and with the people close to you.
