Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| date | Yes | Date of the question, YYYY-MM-DD. | |
| time | Yes | Clock time of the question, HH:mm or HH:mm:ss; gives the hour branch. | |
| timezone | No | 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. | |
| timezoneOffset | No | Hours from UTC at the place of the question; places the lunar day. Defaults to 8, China Standard Time. Ignored when timezone is sent. |
