Who is behind Chinese Zodiac by Year

Chinese Zodiac by Year is published by Radif Partners, a company that builds free reference tools on public data. This one exists because most zodiac charts give one animal per calendar year, which is wrong for many people born in January or February, and because the dates that settle the question are published, for free, by the Hong Kong Observatory.

What the tools do

The sign finder reads the lunar new year of a birth year and returns the animal, element and lunar birthday. The compatibility tool names the traditional relation between two signs. The converter gives the lunar date and solar term of any day from 1901 to 2100. The new year tool gives the date, eve and Lantern Festival of any year. Each animal has a page with all its years and dates.

Where the facts come from

Dates from the Observatory's Gregorian-Lunar conversion tables; the names of stems, branches, hours and months from its pages on the calendar; a few other facts from the pages of public bodies, each cited where it is used. The method page describes the checks.

What we are not

We are not the Hong Kong Observatory or any government body, and we are not astrologers or fortune-tellers. The traits and pairings of the animals are reported as folk tradition. We forecast nothing and give no advice on health, money, work or relationships.

How the site is paid for

Nothing is sold here: no reading, no charm, no affiliate link. If advertising is added one day, it will never sit inside a tool, and it cannot use what you type, which never leaves your browser.

Tell us when something is wrong

If a date differs from the Observatory's table, write to contact@chinesezodiacbyyear.com with the page. The editorial policy explains how a correction is made and dated. The site has 22 pages of tools and guides.
