Example prompt: Can you pull up the full Chinese almanac calendar for July 2025 — I want to see every day's 宜 and 忌 activities, day quality (黄道 or 黑道), day clash, and any solar terms or festivals for the whole month?

## When to prefer this

Use this endpoint when you need a full monthly overview of Chinese almanac data rather than a single day's information. Ideal for building calendar views, monthly planning interfaces, or bulk-scanning an entire month for auspicious days without making 30 individual daily calls.

## Known failure modes

- Invalid month or year returns an error
- Missing payment (x402) results in a 402 Payment Required response
- Out-of-range dates may return empty or partial data
- Network timeout if the upstream almanac data source is unavailable
