Enter the date you were born and this page works out four characters from it — the stem and branch of that day, and of that year. Each of the four belongs to one of the five elements. The one that does not appear is your balancing color.
The day you were born is the character that stands for you. It is the first thing a reader looks at, and it is the only part of a chart that can be worked out from a date alone with no ambiguity.
