Free Vedic Birth Horoscope Calculator

Your free Vedic birth horoscope, calculated instantly

Your Vedic birth horoscope is a map of where the planets stood against the fixed stars at the exact moment you were born. Type your birth date, time, and place into the calculator above and you get your sidereal Sun and Moon signs, your Moon nakshatra and its pada, and your Lagna. It is free, it runs instantly in your browser, and nothing you enter is stored or sent anywhere, no signup needed.

How to use the calculator

1. Enter your birth date. This is the only required field, and the chart already works from the date alone.
2. Add your birth time in local time if you know it. The ascendant, or Lagna, shifts about one degree every four minutes, so an accurate time gives an accurate rising sign. If you leave it blank, the calculator still computes every planet position and simply skips the Lagna, saying so plainly.
3. Set the UTC offset of your birthplace, for example 5.5 for India or -5 for US Eastern Standard Time. Fractional offsets in quarter-hour steps are supported.
4. Enter the latitude and longitude of your birthplace in degrees. The defaults point at New Delhi; change them to your own city for a correct ascendant.
5. Press “Calculate horoscope”. Your Sun rashi, Moon rashi, nakshatra with pada, Lagna, and a full table of all seven sidereal planet signs appear below the form.
6. Use the Copy button to grab a plain-text summary, or Print for a clean paper copy.

If you only know your birth date, that is fine. The Moon moves about 13 degrees a day, so your Moon sign and nakshatra are still right for most of the day. The one thing a missing birth time costs you is the Lagna.

How the calculations work

Vedic astrology uses the sidereal zodiac, measured against the fixed stars. Western astrology mostly uses the tropical zodiac, measured from the seasons. The two frames drift apart by the ayanamsa, currently about 24 degrees, which is why your Vedic signs often sit one sign earlier than your Western ones.

This calculator works in three steps. First it converts your local birth time to UTC using the offset you provide. Then it computes geocentric planetary longitudes with Paul Schlyter’s low-precision planetary theory, the standard open method from “How to compute planetary positions”, solving Kepler’s equation by Newton iteration with full lunar perturbation terms and the published Jupiter and Saturn corrections. The implementation is cross-checked against NASA JPL’s Keplerian Elements for Approximate Positions of the Major Planets, and the whole engine passes an independent test suite that compares its output against JPL DE421 ephemeris data to within a few hundredths of a degree.

Third, it subtracts the Lahiri ayanamsa, the Chitra Paksha value used across Indian ephemerides, anchored at 23.8570833 degrees at J2000 with the standard rate of about 50.29 arcseconds per year. That linear mean model matches published Swiss Ephemeris values to better than one arc-minute across 1900 to 2050. The result is your planets in the sidereal frame, at the given birth moment.

The ascendant comes from a closed-form horizon solution: given local sidereal time from the IAU/Meeus GMST polynomial, your latitude, and the obliquity of the ecliptic, the rising ecliptic point is found analytically and then converted to the sidereal frame the same way. That solution was verified against an independent brute-force horizon root search.

Your nakshatra is the Moon’s lunar mansion: the sidereal zodiac divided into 27 equal mansions of 13 degrees 20 minutes each, starting with Ashwini at zero degrees sidereal Aries. The calculator takes the sidereal Moon longitude, divides by 13.3333 degrees, and the whole-number part picks the nakshatra. Each mansion splits into four padas of 3 degrees 20 minutes, and the pada comes from the remainder. Everything on this page is real astronomy; the short interpretive notes under your Moon sign and nakshatra follow traditional Vedic astrology and are offered for reflection and entertainment, not as fact.

If you want the fuller picture with houses and aspects laid out as a chart, our sidereal natal chart calculator uses the same engine and goes deeper.

Worked example

Here is exactly what the calculator returns for a real set of inputs, so you can see how to read your own result. Take someone born on 24 August 1995 at 2:30 pm local time in New Delhi, India (UTC offset +5.5, latitude 28.6139, longitude 77.2090). The calculator converts 2:30 pm to 9:00 am UTC and computes the chart for that moment with a Lahiri ayanamsa of 23.80 degrees.

The Sun sits at 126.95 degrees sidereal longitude, which is Leo (Simha) at 6.9 degrees into the sign. The Moon sits at 105.82 degrees, which is Cancer (Karka) at 15.8 degrees. In Vedic astrology the Moon sign carries the most weight, so this is first and foremost a Cancer Moon chart. Traditional texts read a Cancer Moon as deep feeling, protectiveness toward loved ones, and a powerful memory, offered here as a traditional interpretation for reflection.

Divide the Moon’s 105.82 degrees by 13.3333 and you get 7.94, so the whole-number part, 7, selects the eighth mansion in the zero-based sequence: Pushya. The remainder places the Moon in the fourth pada. The calculator therefore reports Pushya, Pada 4. Pushya belongs to the Saturn group of nakshatras, whose traditional theme is discipline and endurance: slow, steady effort that compounds over time.

The remaining planets fall as follows: Mercury in Leo at 29.6 degrees, Venus in Leo at 7.9 degrees, Mars in Virgo at 27.1 degrees, Jupiter in Scorpio at 12.4 degrees, and Saturn in Aquarius at 29.1 degrees. The Lagna, computed from the birth time and place, is Scorpio (Vrishchika) at 27.8 degrees, traditionally linked with the outward personality and first impressions.

Notice how the Moon’s position does the heavy lifting in a Vedic reading: Moon sign first, then nakshatra and pada for nuance, then Lagna for the outer style, then the Sun and the rest of the planets for the full picture. Run your own details through the calculator above and read your result in the same order.

Frequently asked questions

How is a Vedic birth horoscope different from a Western birth chart?

The difference is the zodiac. Western astrology mostly uses the tropical zodiac, which is anchored to the seasons and the spring equinox. Vedic astrology uses the sidereal zodiac, anchored to the fixed stars. Because the Earth’s axis precesses, the two frames have drifted apart by about 24 degrees, a gap called the ayanamsa. This calculator uses the Lahiri ayanamsa, the standard in Indian ephemerides, so your Vedic Sun or Moon sign will often be one sign earlier than the sign you know from Western astrology. The planets are in the same physical places; only the measuring frame changes.

Why is the Moon sign the most important in Vedic astrology?

Classical Vedic texts give the Moon’s position, the Janma Rashi, pride of place because the Moon is tied to the mind and emotions in this tradition. Your nakshatra is also read from the Moon, and the Vimshottari dasha system, the timing technique most Vedic astrologers use, starts from the Moon’s nakshatra. That is why this calculator leads with the Moon rashi and the nakshatra rather than the Sun sign: it is following the traditional order of importance, even though the Sun sign is what most Western newspaper horoscopes use.

What is a nakshatra, and why does the pada matter?

A nakshatra is a lunar mansion, one of 27 equal divisions of the zodiac that the Moon passes through roughly one per day. Each spans 13 degrees and 20 minutes. Traditional astrology assigns each mansion a deity, a ruling planet, and a character sketch, which is why two people with the same Moon sign can read very differently. Each nakshatra divides further into four padas of 3 degrees and 20 minutes, and the pada refines the reading the way minutes refine an hour. The calculator derives both directly from the computed sidereal Moon longitude, so there is no lookup table or guesswork involved. If you only need the nakshatra itself, try the dedicated Birth Nakshatra Finder.

Do I need my exact birth time for an accurate horoscope?

You need it for the Lagna and only for the Lagna. The ascendant moves about one degree every four minutes, so even a 15 minute error in birth time can shift it several degrees, and near a sign boundary it can change the sign entirely. The planets move far more slowly: the Sun about a degree a day and the Moon about 13 degrees a day. If you leave the time blank, the calculator computes every planet position for 12:00 UTC on your birth date, skips the Lagna, and tells you it did so. If you know the time within half an hour, enter it; the result page shows the Lagna’s exact degree so you can judge how close to a boundary it sits.

How accurate are the positions, and what should I make of the interpretations?

The positions come from a real astronomical computation: Schlyter’s planetary theory cross-checked against NASA JPL’s Keplerian elements, with the engine verified against JPL DE421 ephemeris data to within a few hundredths of a degree, and the Lahiri ayanamsa matched to published Swiss Ephemeris values within one arc-minute. That is far tighter than hand calculation or printed ephemerides. The short interpretive blurbs for the Moon signs and nakshatra groups are something else entirely: they summarize traditional Vedic astrology as it has been taught for centuries, and they belong in the category of reflection and entertainment. Treat the numbers as astronomy and the meanings as folklore worth sitting with, not as facts about your life.
