Which free kundli website is most accurate, and how to check any of them
Graha Darpan publishes this page and runs one of the calculators it discusses, so weigh it accordingly. You need not take anyone's word, ours included, because the arithmetic of a kundli can be checked in five minutes.
The short answer
There is no single most accurate free kundli website. Planetary positions come from astronomy that every serious calculator shares, so two good sites given the same birth details and settings should agree closely. When they disagree, the cause is nearly always the input (a birth time a few minutes off, a wrong time zone) or a setting, usually the ayanamsa. To check any site, compare the lagna degree, Moon nakshatra and pada, and running dasha dates.
What makes a free kundli website accurate
A kundli, or kundali as some sites spell it, has three layers. The first is astronomy, where the planets stood at one moment, seen from one place. The Swiss Ephemeris and similar ephemerides compute this far more finely than any chart needs, so careful calculators agree on it.
The second is settings, choices the tradition leaves open, such as the ayanamsa, the house system and the kind of lunar node. The third is your input, the date, time and place, and the time zone applied to them. Most complaints that a kundli is wrong begin in these two layers, almost never in the astronomy.
A reading is another matter, an interpretation within a tradition of reflection. This page is about the arithmetic underneath it.
The settings inside every free Vedic astrology chart calculator, starting with ayanamsa
Each setting leaves its own fingerprint, and none of them makes a chart wrong.
- Ayanamsa. The offset between the tropical and sidereal zodiacs. Changing it shifts every planet and the lagna by the same amount. Lahiri (Chitrapaksha) and Raman differ by nearly a degree and a half, as our Lahiri and Raman comparison explains.
- Rahu and Ketu. The true node wobbles around the mean node. Switching moves only the two nodes, slightly.
- House system. Whole sign houses take the lagna's sign as the first house, and other systems divide by degree. Positions stay identical. Only a planet's house can change.
- Chart style. North, South and East Indian charts draw the same numbers. Switching changes nothing computed.
A worked example
We computed one birth with the Swiss Ephemeris, 15 August 1990 at 10:30 IST in Mumbai, under three ayanamsas.
| Ayanamsa | Value for this birth | Lagna |
|---|---|---|
| Lahiri (Chitrapaksha) | 23°43' | Virgo 26°18' |
| Raman | 22°17' | Virgo 27°45' |
| KP | 23°37' | Virgo 26°24' |
All three keep the lagna in Virgo. Raman's sits further along by almost exactly the gap between the ayanamsas, and KP lands a few minutes from Lahiri. Under Lahiri the Moon is in Taurus at 18°55', Rohini pada 3. Every position moves with the setting, so a lagna or Moon near a border can cross into a neighbouring sign, nakshatra or pada.
Now move the clock
Keep Lahiri and change only the time. At 10:26 the lagna is Virgo 25°22', and at 10:34 Virgo 27°15', about one degree for every four minutes.
At 10:45:50 it crosses into Libra. So a time 16 minutes late, easily carried by a rounded note or a family memory, changes the lagna sign and every house with it. By 11:30 the lagna is Libra 10°16'.
India's war time and births from 1941 to 1945
From 1 September 1942 to 15 October 1945, Indian clocks ran at UTC+6:30, an hour ahead of IST, and briefly before that too, from October 1941 to 15 May 1942. Birth times written in those months are war time.
Take 10 March 1944, 06:00, Delhi. With the correct offset the lagna is Capricorn 22°37'. A calculator that assumes UTC+5:30 places the birth an hour later and gives Aquarius 12°03', a different lagna.
Graha Darpan uses the historical time zone database and prints the zone and offset it applied with the chart, so this birth shows UTC+6.5. Elsewhere, if a war time birth shows UTC+5:30, set the zone by hand where the site allows, or enter the clock time less one hour, watching the date near midnight.
A five minute check for any free birth chart kundli calculator online
You need two sites, and Graha Darpan need not be one of them.
- Enter identical details. Date, time to the minute from the birth record with AM and PM checked, and the town of birth, not where you live now.
- Match the settings. Use one ayanamsa on both, Lahiri unless your astrologer uses another, and note each site's time zone.
- Compare the lagna degree. It should agree within a few minutes of arc.
- Compare the Moon's nakshatra and pada. These should match.
- Compare the running dasha. Periods and dates should match closely. If they drift further apart with the years, the sites count the dasha year differently, a convention, not an error.
If they disagree, the pattern points to the cause.
- Everything shifted by the same amount. The ayanamsa differs.
- Planets agree, the lagna does not. The time, place or time zone differs.
- The Moon has moved by degrees too. The date, AM and PM, or time zone is off by hours.
Drik Panchang, AstroSage or Prokerala, which gives an accurate birth chart?
All three offer a free kundli, and on the astronomy we would not rank one above another. They differ in what they let you set, as their own pages showed in October 2026.
| What it shows | Graha Darpan | AstroSage | Drik Panchang | Prokerala |
|---|---|---|---|---|
| Ayanamsa | Lahiri only, value shown | Lahiri, KP New, KP Old, Raman, KP Khullar, Sayan | Lahiri, Raman, Krishnamurthi, Tropical | No selector shown |
| Rahu and Ketu | Mean | Not stated on its form | Mean or true | Not stated on its form |
| Chart styles | North Indian | North, South | North, South, East, West | North, South, East |
| Strongest at | Every position shown with its settings | Widest ayanamsa menu, many languages | Most settings, D1 to D60 charts | Three chart styles, five languages |
AstroSage and Drik Panchang can both be set to Lahiri, which makes the check easy. Prokerala's free kundli showed no ayanamsa selector, so hold its planets against a Lahiri chart first. If every planet differs by the same amount, it uses another ayanamsa, a setting rather than a fault.
Graha Darpan offers the least choice of the four, with Lahiri, whole sign houses and mean nodes in a North Indian chart. If you read with Raman or KP, or want a South Indian chart, AstroSage or Drik Panchang will serve you better, and Drik Panchang also offers true nodes. What we offer is disclosure. Every position is shown to the minute of arc, the settings are named on the chart, and the AI Jyotishi answers only from those computed positions.
Common questions
What is the most accurate free kundli website?
No single site wins, because the astronomy is shared and settled. Given the same birth details and settings, careful calculators agree within a few minutes of arc. Choose one that names its settings, then check it against a second.
Is Drik Panchang, AstroSage or Prokerala more accurate?
On the astronomy we would not rank one above another. With the same details and ayanamsa their charts should agree closely. AstroSage and Drik Panchang let you choose the ayanamsa, and Prokerala's free kundli showed no selector in October 2026.
Which ayanamsa should a free Vedic astrology chart calculator use?
Lahiri, also called Chitrapaksha, is the standard adopted by India's Calendar Reform Committee and followed by most Indian panchangs. Raman and KP have their own schools. Use your astrologer's choice, and the same one on both sites.
My parent was born in India in 1943. Why do sites disagree?
Indian clocks ran at UTC+6:30 from October 1941 to 15 May 1942 and from 1 September 1942 to 15 October 1945. A calculator assuming UTC+5:30 casts the chart an hour late. Check the offset each site applied.
