Dasha-Transit Correlation

Correlates active Vimshottari Dasha lords (maha, antar, pratyantar) with current planetary transits. Returns conjunction and aspect correlations scored by strength, and highlights periods of significance. Aspects are Vedic graha drishti cast by the transiting planet (BPHS Ch.26): every planet aspects its 7th sign, Jupiter also its 5th and 9th, Saturn its 3rd and 10th, Mars its 4th and 8th. Each correlation gives aspect_house (the natal dasha lord's sign counted from the transiting planet, 1 = same sign) and drishti ('7th', '3rd', ...; absent for a conjunction). aspect_type is conjunction, opposition, trine (Jupiter 5th/9th), square (Saturn 10th, Mars 4th) or special (Saturn 3rd, Mars 8th). Request JSON follows BirthInput plus optional target_date, target_time, target_timezone for the analysis moment: name, date, time, location or latitude/longitude/timezone, ayanamsa.

Request parameters

locationoptional

string | null

City name to resolve to lat/lon/tz automatically. Example: 'Mumbai' or 'New Delhi, India'. If provided, latitude, longitude and timezone are not required.

nameoptional

string

Person name associated with the birth record

daterequired

string

Birth date in YYYY-MM-DD format

timerequired

string

Birth time in HH:MM 24-hour format. Required: this endpoint has no sunrise fallback.

latitudeoptional

number | null

Latitude. Required if location not provided.

longitudeoptional

number | null

Longitude. Required if location not provided.

timezoneoptional

string | null

IANA timezone. Required if location not provided (unless utc_offset is given). For dates before the zone adopted a standard time, the birthplace's local mean time (longitude / 15 hours) is used.

utc_offsetoptional

string | null

Optional explicit UTC offset of the birth time, as ±HH:MM or ±HH:MM:SS (e.g. '+04:51:31' for Bombay mean time). Overrides the offset timezone would give. Use it when the birth record states the offset, or for historical local times the IANA database cannot represent.

ayanamsaoptional

string

Sidereal ayanamsa mode used in calculations

target_dateoptional

string | null

YYYY-MM-DD. Defaults to today.

target_timeoptional

string | null

Local clock time HH:MM in target_timezone. Defaults to 12:00. Pass the user's own time so the Moon is where the user sees it.

target_timezoneoptional

string | null

Timezone for target date.

Response fields

success

boolean

True if the request succeeded

message

string

Human-readable status message

data

object

data.birth_time_provided

boolean

True when a birth time was supplied. False when it was not: house, Ascendant and Moon-dependent results then carry the accuracy limits of an unknown birth time.

data.target_date

string

data.active_dasha

object

data.transit_positions

object

data.correlations

array[object]

Dasha lord × transiting planet aspects: dasha_level, dasha_lord, transit_planet, aspect_type (conjunction | opposition | trine | square | special), aspect_house (int 1-12: the natal dasha lord's sign counted from the transiting planet), drishti ('7th', '3rd', '10th', '5th', '9th', '4th', '8th'; absent for a conjunction), score, natal_rashi, transit_rashi, is_retrograde, significance. Aspects are cast by the transiting planet (BPHS Ch.26).

data.periods_of_significance

array[object]

Correlations with score ≥ 2, same shape as correlations.
