Birth Star Chart Calculator

Ayanamsha conventionRaman, Krishnamurti and other schools use different offsets; enter their value explicitly rather than assuming this one.

Explicit ayanamsha value (degrees)Optional. Overrides the computed ayanamsha - required when the convention is "custom".

Date of birth

Time of birth (local)The Moon moves about half a degree an hour, so the nakshatra and dasha balance need an accurate time.

Birth time is known

UTC offset at the birthplace (hours)Include daylight saving if it was in force. India Standard Time is +5.5.

Birth latitude (degrees)

Birth longitude (degrees)Positive east, negative west.

Lunar nodeThe true (osculating) node is a separate convention and is not computed in this version.

Calculation metadata

mode=birth_chart; JD(UT)=2448057.770833; JDE=2448057.771495; ayanamsha=lahiri_iae1985=23.719766 deg; node=mean; feature_set=nakshatra_and_dasha.

Worked out from Rashtriya Panchang / Indian Astronomical Ephemeris, Lahiri (Chitrapaksha) ayanamsa and 2 other sources.

Positions use the lahiri_iae1985 ayanamsha of 23.71977 degrees. Raman, Krishnamurti and other schools shift every longitude, and near a boundary that changes the rashi.

Local clock time and the UTC offset must be the ones actually in force at the birthplace; a wrong offset moves the lagna by 15 degrees an hour.

This engine computes positions only. It makes no prediction and no recommendation about marriage, health, finance or timing, and the interpretive Kundli modules are outside its scope.

How this is worked out

5 steps

Birth moment converted to Julian Day 2448057.77083 UT (JDE 2448057.7715 after Delta T).
Tropical longitudes from the Meeus series, then lambda_sidereal = normalize(lambda_tropical - 23.71977).
Moon at 318.5856 degrees sidereal: Kumbha (Aquarius) 18.59 degrees.
That falls in Shatabhisha pada 4, lorded by Rahu; 1.9094 years of the Rahu mahadasha remained at birth.
Lagna at 145.7078 degrees sidereal: Simha.
