What is a Vedic birth chart?
A Vedic birth chart, or Kundli, is a fixed snapshot of the sky for the exact date, time and place you were born. At its centre sits the Ascendant — the zodiac degree rising on the eastern horizon at that moment — which anchors everything else: every planet's sign, its distance from the Ascendant in houses, and the themes those houses represent.
The chart itself does not change once your birth details are fixed. What can differ between astrologers, and between the pages on this site, is how the twelve houses are drawn from the Ascendant onward — which is exactly what the three calculators below let you compare.
Why the house system is a real choice
Houses answer a structural question: given the Ascendant, where does house one end and house two begin, and so on around the circle? Whole Sign answers it the simplest way — each house is exactly one zodiac sign, full stop. Sripati Bhava Chalit and the KP cuspal scheme both divide the remaining arc unevenly, using the birth time and latitude, so a house can be wider or narrower than 30 degrees.
This is not a disagreement about the sky — the planets sit exactly where they sit regardless of the system. It changes only which house a planet nearest a boundary counts as occupying, which is precisely where reading a second system earns its keep.
Choosing a calculator
Start with Whole Sign if you want the classical Vedic reading most horoscope columns and family astrologers use. Open Sripati Bhava Chalit when you specifically want the traditional Vedic refinement for a planet sitting close to a house edge — it is a distinct, named system in its own right, not a stand-in for Equal House or the Western Porphyry method. Open the KP Cuspal Chart only if you read Krishnamurti Paddhati, because it answers a different question and is fixed to its own ayanamsha.
