Calculators · year animal

Your year animal

A January or early-February birthday usually belongs to the previous animal year. This calculator compares the date with the published first day of the first lunar month instead of subtracting from the Gregorian year.

Date of birth civil date as recorded

Supported dates: 1901–2030. Time and birthplace are not requested because this contract compares civil calendar dates, not a worldwide astronomical instant.

Bodhastra documents what astrological traditions have said, and when they started saying it. It is presented as cultural history and entertainment. Nothing here is medical, psychological, financial or predictive advice, and nothing here is a claim about what will happen to you.
