Periods of the Xuan Kong Da Gua System
The Xuan Kong Da Gua System (64 Hexagrams) also divides time periods in an infinite cycle. However, the length of each of the 8 cycles depends on the lines of the eight trigrams. Each broken line (Yin) represents 6 years, and each unbroken line (Yang) represents 9 years.
