What is a Vedic birth chart?
A Vedic birth chart represents the sky at birth using the sidereal zodiac in the Jyotish tradition. This calculator provides the basic Rashi (D1) chart: seven classical celestial bodies, Rahu and Ketu, the ascendant and twelve houses. Nakshatras and padas are derived from the positions. These are not personality diagnoses or certain predictions.
Why does it differ from a Western birth chart?
Our main calculator uses the tropical zodiac and Placidus houses. This page uses the Lahiri sidereal zodiac and whole-sign houses. A different zodiac origin can move your Sun, Moon or ascendant into another sign. The ayanamsa changes with the date; the calculation does not subtract a fixed 24 degrees from every chart.
How to read your result
Start with the ascendant, called Lagna, and then the Moon sign. In whole-sign houses, the entire rising sign is the first house; subsequent signs become successive houses. Each row gives a body's degree within its sign and its house. A nakshatra is one of 27 equal divisions of the zodiac; each has four padas. An empty house does not mean that area of life is absent.
Method and comparison
Birthplace coordinates and historical time-zone rules convert local birth time to UTC. Swiss Ephemeris calculates Lahiri sidereal positions. Rahu is the mean north lunar node, and Ketu is exactly opposite. To compare tools, match the date, coordinates, UTC time, Lahiri ayanamsa, whole-sign houses and mean-node setting.
Birth time and scope
Do not treat an ascendant or houses calculated from a guessed birth time as certain. Even small differences can change placements near boundaries. Dates from 1900 to 2099 are supported. Ambiguous or nonexistent local times during daylight-saving transitions are rejected. The tool calculates the D1 and Navamsa (D9) charts, the Vimshottari dasha table and the Manglik, Kaal Sarp and Sade Sati checks; it makes no personal predictions.
Rahu and Ketu sign calculator: the lunar nodes in the D1 chart
Rahu (the north lunar node) and Ketu (the south lunar node) are not planets but the two points where the Moon’s orbit crosses the ecliptic. They always sit exactly opposite each other and move backwards through the zodiac. This calculator uses the mean node and shows your Rahu sign and Ketu sign in the result cards, with their degrees, nakshatras and the houses they occupy in the D1 (Rashi) chart. In the Jyotish tradition, Rahu’s house points to where desire and worldly ambition are directed, while Ketu’s house describes inherited habits and a pull towards detachment. Because the nodes take about eighteen and a half years to circle the zodiac, people born in the same year usually share a Rahu sign; the house and nakshatra are what make the placement personal.
Navamsa (D9) chart and vargottama planets
The Navamsa, also spelled Navamsha, is the most consulted of the divisional charts. Each 30-degree sign is split into nine segments of 3°20′, and since that equals one nakshatra pada, the 108 padas of the zodiac map neatly onto D9 signs. Astrologers describe the Rashi chart as the tree and the Navamsa as its fruit: the D9 shows how strong a planet really is and colours questions of marriage, partnership and dharma. A planet placed in the same sign in D1 and D9 is called vargottama and is considered steady and dependable in what it signifies; a vargottama Lagna shares that quality. The D9 Lagna moves to a new sign roughly every thirteen minutes, so its houses need an accurate birth time, whereas the planets’ D9 signs, except sometimes the Moon’s, rarely change within a day.
Vimshottari dasha: mahadasha and antardasha
Vimshottari is the dasha system most Indian astrologers use for timing. Its 120-year cycle runs through nine planetary periods in a fixed order: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19 and Mercury 17. Your starting point comes from the Janma nakshatra, the nakshatra of your natal Moon, since each nakshatra has a ruling planet. If the Moon had crossed 40 percent of that nakshatra, roughly 60 percent of its ruler’s mahadasha remained at birth. Every mahadasha is then divided into nine antardashas in the same order, beginning with its own lord, each lasting in proportion to its share of 120 years. Venus–Venus, for example, runs twenty times twenty divided by 120, or three years and four months. Read the mahadasha as the main theme and the antardasha as the current chapter.
Manglik, Kaal Sarp and Sade Sati: what the checks mean
These three checks are the doshas people hear about most, and each answers a narrow question. The Manglik check looks for Mars in the 1st, 2nd or 4th house, or in the 7th, 8th or 12th, from the Lagna or the Moon, then applies the cancellations for own sign, exaltation and Jupiter. Kaal Sarp asks whether all seven planets are hemmed in between Rahu and Ketu. Sade Sati compares today’s Saturn transit with your natal Moon sign and reports which of its three phases, if any, you are in. None of them measures the whole chart. Regional rules differ, Kaal Sarp is a later addition debated by classical astrologers, and a dosha is always judged alongside planetary strength, dashas and yogas. Read the results as prompts for reflection, never as verdicts or as reasons to buy remedies.
North Indian vs South Indian chart style
This page lets you switch between the two chart styles used across India; the content stays identical and only the drawing changes. The North Indian chart is a square divided into diamonds and triangles. Its houses are fixed: the top central diamond is always the 1st house, and the houses run anticlockwise from there. The small numbers are sign numbers, 1 for Aries through 12 for Pisces, so the number in the top diamond tells you the Lagna. The South Indian chart works the other way round. Its twelve boxes around the edge hold fixed signs, with Pisces in the top-left corner and Aries beside it, continuing clockwise; the Lagna is marked in its sign’s box, and you count houses clockwise from there. Readers from Hindi-speaking regions usually know the first style, while Tamil, Telugu, Kannada and Malayalam speakers often prefer the second.

Vedic birth chart questions
Is the Vedic birth chart calculator free?
Yes. Calculate your ascendant, Moon sign, nakshatra, planets and houses for free without creating an account.
Which ayanamsa does this calculator use?
It uses Lahiri and displays the value for your birth date. Houses use the whole-sign system, and Rahu–Ketu use the mean lunar node.
Can I calculate a chart without my birth time?
This tool requires a time. The ascendant and houses cannot be reliably established without it; the Moon sign and nakshatra may also change during the day.
Why is my Vedic sign different?
The tropical and sidereal zodiacs use different starting points. A changed sign does not by itself indicate an error.
What is my Rahu sign and how is it calculated?
Your Rahu sign is the sidereal (Lahiri) sign the north lunar node occupied at your birth; Ketu is always in the opposite sign. Enter your birth date, time and place, and the result cards show your Rahu and Ketu signs, their degrees and their houses in the D1 chart. This tool uses the mean node, so sites that use the true node may differ by a degree or two.
What is my current dasha?
Enter your birth date, time and place, then look at the dasha table: the mahadasha and antardasha whose date range includes today are the ones running now. Everything starts from your natal Moon’s nakshatra, so a birth time that is an hour off can move the dates by months, and near a nakshatra boundary it can change the whole sequence.
What is vargottama?
A planet is vargottama when it occupies the same sign in the Rashi (D1) chart and the Navamsa (D9) chart. Classical authors treat such a planet as strengthened and consistent, able to express its significations clearly. The term applies to the Lagna too. Compare each planet’s D1 and D9 signs in the Navamsa table to find yours.
Am I in Sade Sati now?
Sade Sati is active while transit Saturn is in the 12th sign from your natal Moon, in the Moon sign itself or in the sign after it. This page checks today’s Saturn position against your sidereal Moon sign and names the phase: rising, peak or setting. Because it uses the Moon sign rather than the Sun sign, your answer may differ from popular horoscope columns.
Is Kaal Sarp dosha dangerous?
No. Kaal Sarp is a pattern, not a danger: every planet falls between Rahu and Ketu. It does not appear in the oldest classical texts, and many respected astrologers give it little weight on its own. Where it is read, it usually describes intense, uneven phases followed by growth. A sudden warning paired with an expensive ritual offer is a reason for caution, not for worry.
