Tung Shing Almanac Skill (通勝黄历)

📦 Also ships as an npm MCP server: npx -y chinese-almanac-mcp · MCP repo →

A Claude Code / Codex / OpenClaw / WorkBuddy skill that queries the 12Zodiacs.com Chinese Almanac API — free, no API key needed for ±90 days.

🌐 About the project — this skill is the open-source client of the Tung Shing engine at 12Zodiacs.com:

• Today's Almanac — the full web app: daily almanac, month calendars, auspicious-date topics, festival dates, and an embedded AI prompt builder
• Methodology — how the engine computes: JPL DE440s ephemeris, the 1739 imperial canon, four-tier spirit arbitration, and validation against mainstream almanacs

What you get: your AI agent can plan real-life events — the best dates for weddings, moving house, business launches, contract signings, car / home purchases, renovations, C-sections, travel, and new-job starts — plus daily auspicious (宜) / avoid (忌) activities, the twelve Day Officers (建除十二神), Yellow/Black Belt hour deities (黃道黑道), zodiac clash (冲煞), lunar dates, and minute-precision 24 solar terms (节气) — computed from JPL DE440s ephemeris and the 1739 imperial canon.

Why 12Zodiacs API?

Most Chinese calendar APIs scrape or approximate. This one is built different:

• Minute-precision solar terms — computed from NASA JPL DE440s ephemeris (not day-granularity lookup tables). 立秋 2026 = Aug 7, 19:42 CST, exact.
• Four-tier spirit arbitration — Day Officers (建除十二神), Yellow/Black Belt deities, and spirit conflicts resolved per the 1739 imperial Qianlong Xie Ji Bian Fang Shu canon, cross-validated against mainstream almanacs (12/12 hour pillars match).
• 1900–2100 coverage — 201 years of lunisolar conversion, leap months, GanZhi pillars, 28 lunar mansions, and festival dates.

Real-Life Scenarios

?activity= accepts all of these natural synonyms (URL-encode Chinese):

Add &weekend_only=1 to restrict results to Saturdays/Sundays (weddings are weekend-driven — roughly 63 of 2026's auspicious wedding days fall on weekends).

Use Cases

• Daily zodiac bot — schedule horoscope for all 12 signs into a Twitter/WeChat/Discord bot pipeline
• Smart scheduling assistant — let your agent check auspicious before booking weddings, moves, or contract signings in calendar apps
• Localización & content pipelines — embed authentic almanac data into CMS workflows, newsletters, or programmatic SEO pages
• MCP servers & agent frameworks — a drop-in cultural data source for any tool-calling agent

Free Tier

• Anonymous: today ±90 days, 30 req/min
• Free key (±365 days, 10/min + 100/day): request here
