In order to draw the yin-yang symbol this is measured by the seasons and the length of the days and nights.

The attached diagram shows six concentric circles (with six intermediate circles), and this group of circles is divided by 12 lines (with 12 intermediate lines) marking the beginning and ending of the signs. The two thicker lines show the winter/summer solstice and the autumn/spring equinox. The thicker third circle marks a halfway point.

See how the curved line begins at the solstices, then the curve exactly intersects all the centre points and the exit points through each sign. When the curve reaches the third circle it is exactly halfway between day and night at the equinoxes where there is half white and half black.

The two small circles, one white and one black, are positioned upon the line of the solstices. The white circle shows where there is white within black when the days of increasing light begin at the winter solstice, and the black circle shows where there is black within white when the days of decreasing light begin at the summer solstice.
