Free Vedic birth chart

How to read your chart

The chart names your ascendant (lagna) - the sign rising on the eastern horizon at your birth moment - and places the nine grahas in signs and houses counted from it. Each planet carries three things worth reading together: its sign, which describes the manner; its house, which describes the area of life; and its nakshatra with a pada number, which is the finer 27-fold division the dasha system is built on.

Below the chart are two tables most free chart generators do not produce. The Sudarshana Chakra counts every planet three times - from the lagna, from the Moon and from the Sun - and sorts the rows by how far those three references disagree. That ordering is the point: a planet that reads the same from all three is telling you what the chart already said, while one that is 2nd from the lagna and 12th from the Moon is genuinely conditional, and the texts read it that way.

The upagraha table lists eight shadow points - Gulika, Mandi, Kala, Mrityu, Ardhaprahara, Yamaghantaka, Indrachapa and Upaketu. They are not planets; they are longitudes derived from the division of day and night, and Gulika in particular is used in classical timing work.

A worked example: 15 August 1947, 00:00 IST, New Delhi

Enter that moment and the ascendant comes out as Taurus 7°44′. The Sun sits in Cancer at 27°59′, in Ashlesha pada 4, in the 3rd house from that lagna; the Moon is also in Cancer, at 3°59′, in Pushya pada 1; Mercury joins them at Cancer 13°40′ in Pushya pada 4. Mars stands apart in Gemini at 7°27′, Ardra pada 1, in the 2nd house.

Now read Mars through the Sudarshana table, which is where this chart stops being a list. Mars is 2nd from the lagna - the house of accumulated resources and family - but 12th from both the Moon and the Sun, the house of expenditure and letting go. Three references, two opposite readings. That is precisely the row the sort brings to the top, and it is the sort of contradiction a single-reference chart hides.

The upagrahas for the same moment put Gulika at Aquarius 26°29′ in the 10th house and Mandi at Pisces 10°56′ in the 11th. Mandi is not an independent calculation: it is the midpoint of Saturn's part where Gulika is its start, which is why the two always sit half a part apart.

How this is computed

Positions are sidereal, using the Lahiri ayanamsa, with whole-sign houses - the classical Vedic standard, and the combination almost all Indian panchang work assumes. Planetary longitudes come from the Swiss Ephemeris, so they agree with published ephemerides rather than with an approximation.

The upagrahas follow the canonical sunrise-anchored scheme of BPHS chapter 6 with the Hari Hara commentary, not the simpler fixed-offset-from-lagna shortcut. For a daytime birth the span from sunrise to sunset is divided into eight equal parts, the first ruled by the weekday lord and the rest following the Chaldean order; for a night birth the same division runs sunset to sunrise and starts from the fifth planet after the day lord. Each upagraha is the sidereal ascendant at the start of its planet's part - and Mandi, alone, at the midpoint of Saturn's.

Where a location has no sunrise or sunset on the day - polar latitudes in summer or winter - the calculation falls back to the older lagna-offset scheme and records that it did, rather than silently returning a number computed a different way.

Common mistakes

The first is comparing a Vedic chart against a Western one and concluding that one is broken. Vedic charts are sidereal and Western charts are tropical, and the two differ by roughly 24° at present - close to a full sign. A Sun that reads Leo in one system and Cancer in the other is the expected result of that offset, not a contradiction.

The second is an imprecise birth time. The ascendant advances through the full zodiac in a day, so it moves about one degree every four minutes and changes sign roughly every two hours. Planetary signs are robust to a wrong birth time; the ascendant, the houses and anything derived from them are not.

The third is the timezone and any war-time or daylight-saving offset in force on the date of birth. This is the single most common cause of a chart that looks almost right but has the ascendant one sign away.

The fourth is expecting the house numbering to match a Western chart. The default here is whole sign, where the ascendant's entire sign is the first house, so a planet late in the ascendant sign sits in the first house even when a quadrant system would place it in the twelfth.

What this chart does not tell you

It is a snapshot, not a sequence. The chart shows where the planets stood; it does not say which period of your life each one governs. That is the dasha system, which needs the Moon's nakshatra as its starting point and runs on its own timetable.

It also says nothing about compatibility, which is computed between two charts rather than read from one, and nothing about the current transit picture - Sade Sati, for instance, depends on where Saturn is now relative to your Moon sign, not on where it was at birth.

One honest caution about birth time. The planets' signs are stable across a whole day, but the ascendant moves roughly one degree every four minutes, so an uncertain birth time affects the lagna and every house placement counted from it first. If your time is approximate, treat the sign positions as solid and the house positions as provisional.
