Example prompt: What is the Chinese lunar calendar date for March 15, 2025? I'd also like to know the zodiac animal and the year pillar name in pinyin.

## When to prefer this

Choose this endpoint when you need authoritative bidirectional conversion between the Gregorian and Chinese lunar calendar, including correct handling of leap months, the sexagenary (stems-and-branches) year cycle, and zodiac animal — especially when the output will be used for traditional Chinese cultural events, birthday calculations, or holiday scheduling between 1930 and 2100.

## Known failure modes

- Date out of supported range (1930–2100) returns an error or empty result
- Malformed date string (wrong format, invalid day/month) causes a validation error
- Leap-month suffix used for a month that is not actually a leap month in that year returns an error
- Missing both 'date' and 'lunar' query parameters results in an error response
- Network or service degradation flag set to true in the response indicating partial/unreliable data

## How this service works

Convert a Gregorian date to the Chinese lunar date (with leap month) or back, plus zodiac animal and year name.

## Output

Returns the Chinese lunar year number, lunar month number, lunar day, a boolean flag for whether the month is a leap month, the number of days in that lunar month, the traditional month name, the year pillar (heavenly stem + earthly branch in Chinese characters and pinyin), the zodiac animal, the corresponding Gregorian date, and a flag indicating whether the date is Chinese New Year's Day.
