Chinese Calendar Data
A lossless, versioned Parquet publication of Chinese calendar, Huangli, lunar phase, solar-term, eclipse, and astronomical-event data generated by CalcChineseCalendar (CCC).
The dataset title intentionally does not contain a year range. Release v1
covers civil years 1950 through 17000, inclusive. Civil dates and times are
stored as numeric columns and never require JavaScript Date.
Release facts
- Civil timezone: UTC+08:00
- Lunar day boundary timezone: UTC+08:00
- Huangli longitude: 120 degrees east
- Ephemeris: JPL DE441, with exact source hashes in
metadata/v1/manifest.json - Huangli profiles:
folk,ziping,purple,xieji - Far-future civil dates use CCC's documented delta-T extrapolation
- Source web-data validation: 15,051/15,051 years passed, zero failed years
Tables
| Config | Row meaning | Important contents |
|---|---|---|
days |
one civil day | Gregorian/lunar date, festivals, daily Moon state, four Huangli profiles, event references |
calendar_months |
one civil month | month metadata and source event/day counts |
calendar_events |
one solar term or exact four-phase event | civil second, JD TDB/UTC, original time strings |
astro_months |
one civil month | observer metadata and source event count |
astro_events |
one astronomy event | typed common event coordinates plus lossless event-specific payload |
eclipse_years |
one civil year | date-assignment and Greatest Eclipse metadata |
solar_eclipses |
one solar eclipse | assignment event plus lossless full technical data |
lunar_eclipses |
one lunar eclipse | assignment event plus lossless full technical data |
Small release metadata remains JSON/Markdown because it is configuration and documentation, not tabular data. All high-volume records are Parquet.
Complex objects that do not yet have one stable cross-kind Arrow schema are
stored as canonical UTF-8 JSON in binary columns. This is deliberate: it
preserves missing versus null, list order, double precision, and all
source-defined fields. metadata/v1/PARQUET_FORMAT.md documents the exact
round-trip rules.
Provenance and validation
The authoritative source manifest, schema, dictionaries, SHA-256 list, and
validation report are published under metadata/v1/. Every published Parquet
file was read back and checked for file hash, schema, row count, canonical
payload parsing, and lossless source-object reconstruction.
