Vedic Nakshatras #

Nakshatras divide the sidereal zodiac into 27 equal segments of 13°20’. Kerykeion computes them in kerykeion/vedic via calculate_nakshatra(), which takes a sidereal longitude and returns the nakshatra name, number (1–27), pada (quarter 1–4) and Vimshottari Dasha lord. The function applies no ayanamsa of its own: the caller must hand it a sidereal longitude.

Basic Usage #

On a sidereal chart, opt in with calculate_nakshatra=True:

from kerykeion import AstrologicalSubjectFactory

subject = AstrologicalSubjectFactory.from_birth_data(
    "Jane", 1990, 7, 15, 10, 30,
    lng=12.4964, lat=41.9028, tz_str="Europe/Rome",
    online=False, zodiac_type="Sidereal", sidereal_mode="LAHIRI",
    calculate_nakshatra=True,
)

print(subject.moon.nakshatra, subject.moon.nakshatra_pada, subject.moon.nakshatra_lord)

On a non-sidereal chart the same flag works, but the nakshatras are placed with nakshatra_ayanamsa (default Lahiri): a tropical longitude passed in raw would land about two nakshatras off, so always set the ayanamsa explicitly.

Each point then carries nakshatra, nakshatra_number, nakshatra_pada and nakshatra_lord; the subject records which ayanamsa was used in nakshatra_ayanamsa / nakshatra_ayanamsa_value.
