The 28 constellations (二十八宿) is concept that is often applied in tandem with the 12 day stars method of date selection.
Also known as the 28 mansions, the Chinese system of 28 constellations is often considered to be the equivalent of the astrological constellations of the western zodiac by those who have studied both.
It is not usually used to select a date, but as a refinement technique to see how good or how bad a day really is for an individual in terms of cosmic energies.
Each day can be represented by one constellations of stars. And 28 of them rotate among themselves with each one reigning supreme on each day.
The 28 members are listed as follows:
- 角 (jiao) horn
- 亢 (kang) neck
- 氐 (di) root
- 房 (fang) house
- 心 (xin) heart
- 尾 (wei) tail
- 箕 (ji) basket
- 斗 (dou) dipper
- 牛 (niu) ox
- 女 (nu) women
- 虛 (xu) empty
- 危 (wei) danger
- 室 (shi) camp
- 壁 (bi) wall
- 奎 (kui) legs
- 婁 (lou) bond
- 胃 (wei) stomach
- 昴 (mao) pleiades
- 畢 (bi) net
- 觜 (zi) beak
- 参 (can) reference
- 井 (jing) well
- 鬼 (gui) ghost
- 柳 (liu) willow
- 星 (xing) star
- 張 (zhang) extend
- 翼 (yi) wings
- 軫 (zhen) chariot
Also take note that number 1 to 7 is associated with the Azure dragon, 8 to 14 with the black tortoise, 15 to 21 with the white tiger, and 22 to 28 with the vermilion bird.
As mentioned earlier, the 28 constellations method is seldom practiced by date selection experts as the main logic behind choosing a day to do specific activities. It is often applied in tandem with other date selecting methods like the 12 day stars.
For example according to 12 day stars, a particular date might seem to be a good day to move into a new house. 28 constellations can then be used to look deeper into how good a day it is exactly.
This also means that when there are a few dates to choose from, the 28 constellations will be able to pinpoint which day among the dates is the best. Conversely, it also means that you can use it to pick the best among the bad dates.
