Natal Chart

Changed on

Calculate a full natal chart: planets, house cusps, aspects, sect, and angular data for a given birth moment. When the birth time is unknown, send timeUnknown: true instead of time and the response carries planets and aspects with houses, angles and sect set to null, plus a timeUnknown block giving the range the Moon covers that day. With ?lang= the response adds localized: planet, sign and aspect names in that language, keyed by the English names.

Example:de

Adds localized: planet, sign and aspect names in this language, keyed by the English identifiers the response already uses. Without it the response is unchanged; Accept-Language alone does not add it.

fieldsstring

Comma-separated dotted paths, relative to data, to keep in the response. A path is applied to every element of an array, so planets.name means the name of each planet. Paths that match nothing come back in _fields_unmatched; a list where nothing matches at all is a 400, because an empty object would be a confident wrong answer.

precisioninteger

Round every non-integer number in the response to this many decimal places. Integers are left alone, because an id is not a measurement. Ecliptic longitudes ship with fourteen decimals by default; 2 is about a tenth of an arcminute.

Request body

datestring required
timestring
timezoneOffsetnumber nullable

Hours from UTC at the given moment, not minutes. Fractional zones are hours too: 5.5 for India, 5.75 for Nepal, -3.5 for Newfoundland. Defaults to 0, meaning UTC. Ignored when timezone is sent.

timezonestring

IANA zone name such as Europe/Kyiv, or auto to look the zone up from latitude and longitude. The server takes the offset that zone kept at this local date and time, summer time included, and uses it in place of timezoneOffset. A clock time that happened twice takes the first occurrence; one skipped when clocks went forward takes the offset from before the change. Abbreviations such as EST are refused. Before 1970 the tz database is not reliable for every place, so send timezoneOffset when the local clock is known.
