# Chinese zodiac

```ruby
func zodiac(year) {
  var animals = %w(Rat Ox Tiger Rabbit Dragon Snake Horse Goat Monkey Rooster Dog Pig)
  var elements = %w(Wood Fire Earth Metal Water)
  var terrestrial_han = %w(子 丑 寅 卯 辰 巳 午 未 申 酉 戌 亥)
  var terrestrial_pinyin = %w(zĭ chŏu yín măo chén sì wŭ wèi shēn yŏu xū hài)
  var celestial_han = %w(甲 乙 丙 丁 戊 己 庚 辛 壬 癸)
  var celestial_pinyin = %w(jiă yĭ bĭng dīng wù jĭ gēng xīn rén gŭi)
  var aspect = %w(yang yin)

  var cycle_year = ((year-4) % 60)
  var (i2, i10, i12) = (cycle_year%2, cycle_year%10, cycle_year%12)

  (year,
   celestial_han[i10],    terrestrial_han[i12],
   celestial_pinyin[i10], terrestrial_pinyin[i12],
   elements[i10 >> 1], animals[i12], aspect[i2], cycle_year+1)
}

[1935, 1938, 1968, 1972, 1976, 2017].each { |year|
    printf("%4d: %s%s (%s-%s) %s %s; %s - year %d of the cycle\n", zodiac(year))
}
```

## Output:

```
1935: 乙亥 (yĭ-hài) Wood Pig; yin - year 12 of the cycle
1938: 戊寅 (wù-yín) Earth Tiger; yang - year 15 of the cycle
1968: 戊申 (wù-shēn) Earth Monkey; yang - year 45 of the cycle
1972: 壬子 (rén-zĭ) Water Rat; yang - year 49 of the cycle

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://trizen.gitbook.io/sidef-lang/programming_tasks/c/chinese_zodiac.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
