How to Read Your Janam Kundali — Birth Chart Basics for Beginners

A Janam Kundali (जन्म कुण्डली), also called a birth chart or horoscope, is a map of the sky at the exact moment of your birth. It shows the position of the Sun, Moon, and all planets across the 12 houses and 12 zodiac signs. In Telugu, it is called జాతకం (Jathakam) or జన్మ పత్రిక (Janma Patrika).

South Indian vs. North Indian Chart Format

There are two ways to draw a kundali:

• South Indian format — A fixed 4×4 grid where the zodiac signs are always in the same position. The lagna (ascendant) house is marked with a diagonal line. This is the format used in Andhra Pradesh, Telangana, Tamil Nadu, and Karnataka.
• North Indian format — A diamond-shaped chart where houses are fixed but signs rotate. More common in North India.

Our Jyothishamu Kundali tool generates the South Indian format — the traditional format for Telugu astrology.

The 12 Houses (Bhava)

The 12 houses represent 12 areas of life. The Lagna (1st house) is the most important — it is the zodiac sign rising on the eastern horizon at birth:

1. 1st House (Lagna) — Self, personality, health, appearance
2. 2nd House — Wealth, family, speech, early education
3. 3rd House — Siblings, courage, communication, short travels
4. 4th House — Mother, home, property, happiness
5. 5th House — Children, intelligence, education, creativity
6. 6th House — Enemies, diseases, debts, service
7. 7th House — Marriage, partnerships, business
8. 8th House — Longevity, inheritance, secrets, transformation
9. 9th House — Luck, father, religion, higher education
10. 10th House — Career, profession, status, authority
11. 11th House — Gains, income, elder siblings, social network
12. 12th House — Expenses, foreign lands, liberation, losses

The 9 Planets (Navagraha)

Vedic astrology uses 9 grahas (planets):

• Surya (Sun) — Soul, authority, father, government
• Chandra (Moon) — Mind, emotions, mother, public
• Mangal (Mars) — Energy, courage, siblings, property
• Budha (Mercury) — Intelligence, communication, business
• Guru (Jupiter) — Wisdom, children, wealth, spirituality
• Shukra (Venus) — Love, beauty, arts, luxury
• Shani (Saturn) — Discipline, hardship, longevity, karma
• Rahu — Shadow planet; ambition, foreign connections, obsessions
• Ketu — Shadow planet; spirituality, detachment, past lives

Rahu and Ketu are always exactly opposite each other in the chart and are calculated mathematically as the Moon's nodes.

Understanding Vimshottari Dasha

The Vimshottari Dasha system divides your life into planetary periods spanning a total of 120 years. Each planet rules a period of specific length:

• Ketu — 7 years
• Venus — 20 years
• Sun — 6 years
• Moon — 10 years
• Mars — 7 years
• Rahu — 18 years
• Jupiter — 16 years
• Saturn — 19 years
• Mercury — 17 years

The starting Dasha is determined by your nakshatra (birth star) and the Moon's exact position within it. Each major period (Maha Dasha) is subdivided into sub-periods (Antardasha). This system is used to predict the timing of life events — when you might get married, change jobs, or face health challenges.

Reading Your Own Kundali — First Steps

1. Identify your Lagna — the house marked with a diagonal line (South Indian chart). The sign in that house is your ascendant.
2. Find your Moon (Ch or ☽) — the sign it occupies is your Rashi.
3. Note your current Maha Dasha — this planetary period colors your entire life experience right now.
4. Look at the 7th house for marriage, the 10th for career, the 5th for children.
