Zi Wei Dou Shu (Purple Star)

Four Transformations (四化)

Changed on

The four stars activated by the birth year stem: 化禄 fortune, 化权 authority, 化科 repute, 化忌 obstruction. The one part of Zi Wei computable without star placement. Seven stems are agreed across traditions; for the three that are not (戊 庚 壬) every school reading ships in schoolVariants, and school switches the headline answer.

Query parameters

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

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.
