Add a date and historical UTC offset for the seven visible planets. Add a recorded time and coordinates only when you also want a sidereal Ascendant.
THE ANSWER, WITH ITS SCOPE
A Vedic chart starts with sidereal placements, but a full chart needs a recorded time and place.
This tool calculates a Lahiri sidereal baseline for the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn. With a recorded time, latitude and longitude, it also calculates a sidereal Ascendant. It does not create a Navamsha, Dasha or prediction report.
Three input states
- Can calculate the baseline
- Date and historical UTC offset are present. An unknown time uses noon and is labeled as an estimate.
- Can calculate Lagna
- A recorded time, latitude and longitude are also present.
- Needs checking
- The time is missing, the historical offset is uncertain, or coordinates are absent. Keep houses and Lagna unresolved.
WHAT TO CHECK AGAINST YOUR CHART SERVICE
Compare settings before comparing labels.
Open your existing chart service and look for its zodiac and ayanamsa settings. A service set to tropical zodiac, or to a sidereal ayanamsa other than Lahiri, can show different signs even when the birth inputs match. This page keeps “sidereal / Lahiri,” the UTC conversion and Julian day in the receipt so the calculation can be repeated rather than guessed from a label.
Planetary placements can be a useful date-level baseline. Houses and Lagna are not: they depend on the horizon at a time and location, so this tool leaves them blank if that information is missing.
QUESTIONS BEFORE INTERPRETATION
Use the result without silently changing the model.
What is this Vedic astrology calculator calculating?
It calculates seven geocentric planetary longitudes in the Lahiri sidereal zodiac. With time and coordinates, it also calculates a sidereal Ascendant.
Why does another Vedic chart show a different sign?
First compare birth time, historical UTC offset, coordinates, zodiac type and ayanamsa. A different setting changes the calculation itself; it is not merely a different interpretation.
Can I calculate a Vedic chart without a birth time?
You can see a noon-estimated planetary baseline, but not a reliable Lagna or house result. Keep those fields unresolved until the birth time and coordinates are available.
Does this calculate nakshatras or Dasha?
No. This page deliberately stops at the visible sidereal baseline and its receipt rather than presenting uncalculated advanced-chart results.
