“Element” can appear more than once because the calendar is describing different positions. The result labels the source of each value before it offers a deeper interpretation.

Using the calculator
Calculator questions
Why does the calculator not use January 1?
The Chinese zodiac is tied to the lunar calendar. A zodiac year starts at Chinese New Year, which falls between 21 January and 20 February, so anyone born in January or early February must be checked against that year's boundary rather than the Gregorian year.
What dates can I enter?
The calculator covers every birth date from 1901-02-19 through 2100-02-08.
Why does the result show three element coordinates?
The year-stem element belongs to the birth year's heavenly stem, the fixed element belongs to the animal's earthly branch, and the day master comes from the birth date's day stem. They describe different positions and should not be collapsed into one label.
What is the Na Yin name?
Na Yin is a named element association attached to each two-year stem-and-branch pair in the sixty-year cycle. It is another classification, so the result keeps it separate from both the year-stem element and the animal's fixed element.
