Some practical date selection example retrospection

This appears to be an acceptable Xuan Kong Da Gua date.

18th June 2010. 9-11AM GMT+8

Hr Day Month Year Dweller House Sitting
Ji Ji Ren Geng Wu Ding
Si Hai Wu Yin Shen Chou
8 2 2 3 2 4
2 2 1 1 6 7

Want to take a crack on possible weakness for this date?

The Si-Hai clash, using the family relation can be defended. The house sitting Chou was briefly discounted using a Wu month.

The main weakness is more insidious. It comes from the interaction between date time's month-year against the dweller's year pillar. There seems to be indeterminate gender. Dweller child gua meeting different and competing parent guas in month and year.

Dweller birth year XK numerals could be child of Xun or Kan group and coincidentally meets Xun and Kan parent in the date time month and year pillars

Summary
82 is (Tai) Type: Son
82 is (Heng) Type: Daughter

22 is (Pi) Type: Daughter
22 is (Yi) Type: Son

*21 is (Xun) Type: Mother

*31 is (Li) Type: Mother

26 is (Xun) Type: Son
26 is (Kan) Type: Daughter

There are two variants to this approach.

Variant 1:
Geng Yin only has the parent Xuan Kong (XK) numerals for date selection.

Variant 2:
Geng Yin can take 2 XK numerals for date selection, use the better one that has utility.

Hence this date can be defended if variant 2 practitioners assume Geng Yin can take the (4,2) numerals and hence avoiding the indeterminate gua taboo.

Variant 1 will probably scoff at the idea.

Supporters of variant 1 and 2, what are your take.

Personally I go for variant 1.

Wicked question, if variant 1 is correct, how serious is violating indeterminate gender taboo?

We can use other date selection systems other than Xuan Kong Da Gua. Let us take a look at the 9 Palace Qi Men Dun Jia for 18th June 2010, 9-11AM GMT+8.

The saving grace is the Wu stem is in a good palace, south west and 天辅时辰 may defend the defects in the gender indeterminate taboo earlier but alas 8 Door Fan Yin.

See attachment for the Zhi Run, Rotating Palace chart.

Oh wait a minute, there is another San Yuan Qi Men Dun Jia.....

Therefore it makes better business sense to do just Feng Shui rather than date selection. The amount of work for date selection is not as simple as plotting a few charts or using powerful computing aids.
