What this is
For entertainment and self-reflection. Not professional advice.
This site takes a birth date and returns a character drawn from a traditional East Asian calendar system, plus a label for how two characters relate. It is a game about a calendar, not a service that evaluates people.
Who can use it
This is for adults 18 and over. We work out your age from the date you enter, then discard it.
What we ask of you
Enter your own birth date, not someone else's. There is no way to add another person to a map on their behalf, and that is deliberate.
Availability
This is a short experiment. It may change or stop at any time, and maps may be removed when it ends.
No warranty
The site is provided as is, without warranties of any kind, to the extent permitted by law.
