Astrology 101

The sky and the system

The planets are real. The positions are maths. The meanings come from India's oldest astrology texts. Here's how it all fits — in 5 minutes.

How your chart is made

  1. 01

    Your exact sky

    Your date, time and place of birth give the precise position of every planet at that moment — calculated from real astronomy, accurate to the arc-minute.

  2. 02

    Measured against the stars

    Vedic astrology uses the sidereal zodiac, aligned to the fixed stars. Because Earth's axis slowly wobbles, it now sits about 24° behind the Western zodiac — which is why your Vedic sign often differs.

  3. 03

    Houses from the horizon

    Whichever sign was rising on the eastern horizon at your birth becomes house 1. The other 11 follow — each one a different area of life.

  4. 04

    Read with classical rules

    Planet + sign + house + timing (dasha) are read with rules from texts like Brihat Parashara Hora Shastra and Phaladeepika. That part is tradition — 2,000 years of pattern-reading, not lab science.

The 9 grahas — your cast of characters

Graha means “that which grabs” — each one pulls a part of your life into focus.

Sun

Main-character energy

Identity, confidence, authority, father, career visibility.

Real sky: The star itself — Earth's yearly orbit makes it cross one sign every month.

Moon

Your mood and inner world

Mind, emotions, mother, comfort, how you feel day to day.

Real sky: Circles Earth every 27.3 days — that's where the 27 nakshatras come from.

Mars

Drive, courage, gym energy

Energy, courage, competition, siblings, property, technical skill.

Real sky: Takes 687 days to orbit the Sun; stays about 45 days in each sign.

Mercury

Big-brain, quick-talk energy

Intellect, communication, business, writing, tech, learning.

Real sky: Fastest planet — 88-day orbit, never more than 28° from the Sun.

Jupiter

The mentor, luck and growth

Wisdom, growth, money, teachers, children, good fortune.

Real sky: Largest planet; 11.9-year orbit, so about one year in each sign.

Venus

Love, aesthetics, the good life

Love, relationships, beauty, art, comfort, luxury.

Real sky: 225-day orbit; the brightest planet in our sky.

Saturn

Strict coach: discipline pays

Discipline, hard work, delays, responsibility, long-term results.

Real sky: 29.5-year orbit — about 2½ years in each sign, so its lessons are long.

Rahu

Ambition, obsession, the new & foreign

Ambition, technology, foreign lands, unconventional paths, sudden rise.

Real sky: Not a planet — the point where the Moon's orbit crosses the Sun's path. Eclipses happen here. Cycle: 18.6 years.

Ketu

Detach, go deep, spiritual

Detachment, intuition, research, spirituality, letting go.

Real sky: The opposite lunar node to Rahu — always exactly 180° away.

The 12 houses — the stages of your life

A planet in a house = that character shows up in that part of your life.

  1. 1

    self & body

    How you show up, your body, your default vibe

    money & family

    Savings, family, food, the way you talk

  12. 12

    expenses, foreign & sleep

    Spending, going abroad, sleep, letting go

Dashas — your life runs in chapters

The Vimshottari system splits a 120-year cycle between the 9 grahas. Which chapter you were born into depends on exactly where the Moon was — so two people born a few hours apart can live different chapters at the same age.

Nakshatras: the Moon's 27 rest stops

The Moon circles Earth in about 27.3 days, so the sky is split into 27 star zones of 13°20′ each — roughly one per day. Your birth nakshatra (where your Moon was) sets your first dasha and shapes your emotional style.

Transits & Sade Sati — not a curse

Planets keep moving after you're born. Saturn takes ~2½ years per sign, so when it passes over your Moon sign and the signs either side, that's Sade Sati — about 7½ years of pressure, responsibility and growing up fast. Many people build their careers in it.
