Plum blossom easy-to-count calendar old yellow calendar

What you're talking about should be the time divination method in The Book of Changes of Plum Blossoms, which is based on the lunar calendar. For example, today is July 25th, 2008 at 2 1: 20, which translates into the lunar calendar as June 23rd, the year of Wuzi.

The last hexagram: 1+6+23=30*8= the remaining 6 are hexagrams.

The next divination: 1+6+23+ 12= 42*8= the remaining 2 is divination.

Dynamic: The total number of years, months, days and hours =42*6, which is the sixth.

But the divination of time is not based on the date of birth.
