Monthly Envoy Adding the Hour (月将加时 Yuè Jiāng Jiā Shí): The Foundation of Da Liu Ren Divination

Overview

Monthly Envoy Adding the Hour (月将加时 Yuè Jiāng Jiā Shí) is the foundational cosmological engine of Da Liu Ren (大六壬, literally "Great Six Ren"), one of the three highest forms of Chinese classical divination alongside Qi Men Dun Jia (奇门遁甲) and Tai Yi Shen Shu (太乙神数). This technique establishes the dynamic relationship between celestial movements and terrestrial time, creating the rotating Heaven Plate (天盘 Tiān Pán) that interacts with the fixed Earth Plate (地盘 Dì Pán).

In practical terms, "月将加时" describes the method of superimposing the Monthly Envoy—a celestial marker representing the sun's apparent position in the earthly branch zodiac—onto the specific Earthly Branch (地支 Dì Zhī) corresponding to the time of inquiry. This alignment generates the spatial-temporal matrix from which all subsequent interpretive elements emerge, including the Four Classes (四课 Sì Kè) and Three Transmissions (三传 Sān Chuán). Without correctly establishing this relationship, the entire divination framework collapses, making this technique the critical first step (Qi Ke 起课, "raising the lesson") in every Da Liu Ren consultation.

Key Concepts

The Monthly Envoy (月将 Yuè Jiāng)

The Monthly Envoy, also called Jiang Shen (将神, "Commander Spirit"), represents the sun's residence in the twelve-branch zodiac system during a given solar month. Unlike lunar months used in some folk systems, Da Liu Ren employs Solar Terms (节气 Jié Qì), with each envoy governing the period between specific solar markers. The twelve envoys possess both branch identities and poetic names reflecting their symbolic nature:

• Hai (亥) - Deng Ming (登明, "Ascending Brightness"): Associated with concealment and water
• Xu (戌) - He Kui (河魁, "River Champion"): Linked to earth and cemeteries
• You (酉) - Cong Kui (从魁, "Following Champion"): Metal element, autumn harvest
• Shen (申) - Chuan Song (传送, "Transmission"): Travel, messages, metal
• Wei (未) - Xiao Ji (小吉, "Small Auspicious"): Earth, marriage, kitchens
• Wu (午) - Sheng Guang (胜光, "Surpassing Light"): Fire, imperial examinations, letters
• Si (巳) - Tai Yi (太乙, "Great Unity"): Fire, confusion, armaments
• Chen (辰) - Tian Gang (天罡, "Heavenly Steel"): Earth, law, authority
• Mao (卯) - Tai Chong (太冲, "Great Surge"): Wood, vehicles, roads
• Yin (寅) - Gong Cao (功曹, "Merit Minister"): Wood, documents, elders
• Chou (丑) - Da Ji (大吉, "Great Auspicious"): Earth, gentleness, alliances
• Zi (子) - Shen Hou (神后, "Divine Empress"): Water, secrecy, theft, pregnancy

The Hour Branch (时辰 Shí Chen)

Traditional Chinese chronology divides the day into twelve Double Hours (时辰), each governed by an Earthly Branch. Unlike modern hourly systems, these periods follow celestial rather than civic time:

The Two Plates (天地盘 Tiān Dì Pán)

The Earth Plate represents the static, terrestrial realm—a fixed ring of twelve earthly branches arranged in their standard directional order (Zi north, Wu south, etc.). The Heaven Plate represents celestial movement and change, rotating according to the Monthly Envoy's relationship to the Hour Branch. When superimposed, they create twelve palaces (宫 Gōng) where heavenly stems, earthly branches, and spirits interact.

How It Works: The Method

The procedure follows a precise astronomical-logical sequence. Mastery requires understanding both the lookup tables and the underlying rotational mechanics.

Step 1: Determine the Correct Month (月建 Yuè Jiàn)

First identify the current Month Establishment based on Solar Terms, not the lunar calendar:

• Yin (寅) Month: Begins at Li Chun (立春, Establishing Spring)
• Mao (卯) Month: Begins at Jing Zhe (惊蛰, Awakening Insects)
• Continue through the twelve branches...

Step 2: Identify the Monthly Envoy

Using the Month Establishment, locate the corresponding Envoy through this traditional correlation:

Mnemonic Rhyme (口诀 Kǒu Jué):
"Zhèng Hài, Èr Xū, Sān Yǒu, Sì Shēn; Wǔ Wèi, Liù Wǔ, Qī Sì, Bā Chén; Jiǔ Mǎo, Shí Yín, Shí Yī Chǒu, Shí Èr Zǐ."
(First month Hai, second Xu, third You, fourth Shen; fifth Wei, sixth Wu, seventh Si, eighth Chen; ninth Mao, tenth Yin, eleventh Chou, twelfth Zi.)

Step 3: Apply the Hour and Rotate

Once you have the Envoy (e.g., Shen 申 for a Si-month reading) and the Hour Branch (e.g., Chen 辰 for 7:00–9:00 AM):

1. Visualize or draw the fixed Earth Plate with Zi at north (bottom), moving clockwise through Chou, Yin, Mao, etc.
2. Take the Monthly Envoy (Shen/Monkey) and place it directly on top of the Hour Branch position (Chen/Dragon) on the Earth Plate.
3. Arrange the remaining eleven branches clockwise (顺行 Shùn Xíng) around the circle, maintaining their standard sequence.

This creates the Heaven Plate: Shen sits atop Chen, You atop Si, Xu atop Wu, Hai atop Wei, Zi atop Shen, Chou atop You, Yin atop Xu, Mao atop Hai, Chen atop Zi, Si atop Chou, Wu atop Yin, and Wei atop Mao.

Practical Example

Scenario: A querent asks about career prospects on the 15th day of the fifth lunar month (which falls within the Grain Rain to Minor Fullness solar period) at 3:30 PM.

• Solar Month: Wu (午) month → Monthly Envoy: Wei (未, Xiao Ji)
• Time: 3:30 PM falls within Shen Hour (申时, 15:00–17:00)
• Action: Place Wei (未) atop Shen (申) on the Earth Plate
• Resulting Heaven Plate sequence (clockwise from Shen hour):
  Shen position: Wei
  You position: Shen
  Xu position: You
  Hai position: Xu
  Zi position: Hai
  Chou position: Zi
  Yin position: Chou
  Mao position: Yin
  Chen position: Mao
  Si position: Chen
  Wu position: Si
  Wei position: Wu

This specific alignment now allows the diviner to calculate the Four Classes by comparing the Day Stem and Day Branch against these overlapping positions.

Applications in Chart Interpretation

The Heaven Plate generated through Yue Jiang Jia Shi serves as the celestial matrix for three critical divinatory structures:

Deriving the Four Classes (四课 Sì Kè)

The Four Classes represent four layers of relationship between the querent (Day Stem 日干 Rì Gān) and the situation. By comparing where the Day Stem and Day Branch "land" on the Heaven Plate versus their Earth Plate positions, practitioners identify:

• First Class: Heaven Plate position of the Day Stem's root
• Second Class: Earth Plate position beneath the Day Stem's Heaven Plate position
• Third Class: Heaven Plate position of the Day Branch
• Fourth Class: Earth Plate position beneath the Day Branch's Heaven Plate position

Calculating the Three Transmissions (三传 Sān Chuán)

From the Four Classes, the Three Transmissions (Initial 初传, Middle 中传, Final 末传) are derived using methods such as Bie Ze (别责, Alternative Responsibility) or Bi Yao (比用, Comparison and Application). These represent the progression of the matter through time—beginning, development, and conclusion.

Assigning the Twelve Heaven Spirits (十二天将 Shí Èr Tiān Jiàng)

Once the Initial Transmission is determined, the Twelve Heaven Spirits (Gui She 贵人, Teng She 螣蛇, Zhu Que 朱雀, etc.) are arranged around the Heaven Plate starting from specific positions determined by the Day Stem and the location of Gui Shen (贵人, the Noble Spirit). Their interaction with the branches on the Heaven Plate provides the qualitative coloring of events—whether forces are benevolent, obstructive, deceptive, or supportive.

Common Pitfalls

Even experienced practitioners encounter errors in this foundational step:

• Solar vs. Lunar Confusion: Using the lunar month number directly instead of checking the Solar Term (节气). For instance, if a query occurs in the "first lunar month" but before Li Chun (立春), the Month Establishment is still Chou (丑), not Yin (寅).
• Counter-clockwise Rotation: Some systems rotate counter-clockwise, but standard Da Liu Ren requires clockwise (顺行) arrangement of the Heaven Plate branches.
• Daylight Saving Time Neglect: Failure to adjust for historical daylight saving changes can shift the Hour Branch by one position, completely altering the chart.
• Fixed vs. Moving Plates: Confusing which plate moves—the Earth Plate never moves; only the Envoy "moves" to sit atop the Hour, dragging the sequence with it.
• Zi Hour Ambiguity: The Zi hour (23:00–01:00) spans two calendar days. Traditional practice usually assigns the early Zi (23:00–00:00) to the previous day, but some modern systems use midnight cutoff, creating potential discrepancies.
