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.

Request Body^required

application/json

Birth data where the clock time may be unknown. Either pass time (HH:mm:ss), or set timeUnknown: true and omit it. In the second case the response carries planets and aspects but no houses, angles or sect.

timezoneOffset

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.
