# Practice exercise 4, questions 6 and 7 (Early Zi and Day Stem)

I do not get the same answer as you did.

Hello again Gabriel,

The key to both of these questions is to remember NOT to use the early Zi 子 method in your calculations. You will the early Zi method explained in the “Find the Day Pillar” section of chapter 1.

A reminder not the use the early Zi method for the Hour Pillar calculations is found in the “Define the BaZi Hour” section of Chapter 1.

As it is a mistake that many students often take a misstep, I have also added it as a bulleted “reminder” in the Hour Pillar Calculation summary box (found on page 71 of the paper copy of the book).

### Find the Hour Pillar: 18 April 1979 @ 23:30 (Female)

First, determine the Day Pillar

We know the Day Pillar (because we previously calculated it in Practice Exercise 3) is #52, YiMao 乙卯. The temptation is to use this information in the HS equation. However, please remember that we are NOT supposed to use the early Zi method in the DP equation!

There are two ways to approach this.

1.Calculate the DP value again, this time using birthdate + 1 in the DP equation (because we do not use the early Zi method to find the Hour Pillar):

DP = R (of 395 + 19 + 9 + 19 + 1 + 30] / 60

DP = R of (473/60)

DP = #53 (BingChen 丙辰)

2. A short cut, if you don’t want to work the DP calculation again, is to know that when you add one to the birthdate, you will essentially move one up in the sexagenary cycle chart. So in this example, we know the person’s Day Pillar is #52, YiMao 乙卯. Now, move one up in the cycle and you will know that we will use #53 BingChen 丙辰 in the Hour Pillar calculations.

Use the adjusted DP pillar information to find the Hour Stem:

Then, use the HB and HS formulas to find the Hour Stem:

(from the answers above, Bing 丙 = #3, as per Heavenly Ring diagram)

HS = (3 X 2) + (1 -2)

HS = 5 (Wu 戊)

HB = Zi 子 (#1, as per Earthly Ring diagram and Earthly Branch and Time of Day chart)

Day Pillar is WuZi 戊子

### Practice exercise 4, question 7:

Find the Hour Pillar: 7 November 1985 @ 23:11 (Male)

As above, first determine the Day Pillar.

Either recalculate the DP using the birthdate + 1 or move up one position from your previous DP calculation of this birthday (#47 GengXu 庚戌, from Practice Exercise 3, question 7) in the sexagenary cycle chart.

DP = R of [425 + 21 + 9 + 8 + 5 + 0] / 60

DP = R of (468/60)

DP = #48 XinHai 辛亥 (#47 GengXu 庚戌 + 1)

Then, use the HB and HS formulas to find the Hour Stem:

(from the answer above, Xin 辛 = #8, as per Heavenly Ring diagram)

HS = (8X2) + (1-2)

HS = 16 – 1 = 15 (subtract 10)

HS = 5 Wu 戊)

HB = Zi 子 (#1, as per Earthly Ring diagram and Earthly Branch and Time of Day chart)

Hour Pillar is WuZi 戊子

I hope this helps!

Dear Karin
Thank for these explanations, I’ll try to go through. Are you giving seminars around this topics or can you recommend some?
Have a nice day!

Hello Gabriel!

You are very welcome 🙂

I may focus more on teaching in the future, once my daughter is in school full time (…still several years from now). However, my husband and I have developed our GanZhi Advanced Daoist Arts Program (https://chinesewisdomtraditions.com/ganzhi-advanced-daoist-arts-program/) for this purpose.

We just started a new course in Dec 2018, so we will likely plan on opening the next course in 2020 or 2021?

Best regards,

Karin
