Adding the Monthly Envoy to the Hour (月将加时)

Overview

Adding the Monthly Envoy to the Hour (月将加时, Yuè Jiàng Jiā Shí) is the fundamental cosmological calculation in Da Liu Ren (大六壬, "Great Six Ren"), one of the three highest forms of Chinese classical divination alongside Qimen Dunjia (奇门遁甲) and Taiyi Shenshu (太乙神数). This technique establishes the sacred geometry that connects celestial time (the solar month) with earthly time (the double-hour), creating a dynamic matrix known as the Heaven Plate (天盘, Tiān Pán) overlaying the static Earth Plate (地盘, Dì Pán).

The term "月将" (Yuè Jiàng) refers to the "Monthly General" or "Monthly Envoy"—the specific Earthly Branch (地支, Dì Zhī) that represents the sun's celestial station for a given solar month. "加时" (Jiā Shí) literally means "adding the hour," describing the mechanical process of positioning this Monthly Envoy upon the Earthly Branch corresponding to the time of divination. This act generates the rotational framework necessary to derive the Four Classes (四课, Sì Kè) and Three Transmissions (三传, Sān Chuán) that form the interpretive backbone of a Da Liu Ren reading.

The Twelve Monthly Generals (十二值月将)

Unlike the common lunar calendar used in folk traditions, Da Liu Ren employs the solar calendar divided by the 24 Solar Terms (节气, Jié Qì). The Monthly Generals represent the sun's monthly "envoys" or stations, moving in reverse order through the Earthly Branches compared to the standard sequence. Each General carries specific astrological significance and governs the qualitative nature of events during its reign.

The Twelve Double-Hours (十二时辰)

In Chinese temporal cosmology, the day is divided into twelve Shi Chen (时辰), each spanning two hours and governed by an Earthly Branch. Unlike the Monthly Generals which move retrograde, the daily hours proceed in the standard clockwise order of the Earthly Branches. Accurate determination of the current Shi Chen is essential for the 月将加时 calculation.

Key Concepts: Heaven Plate and Earth Plate

The mechanics of 月将加时 revolve around the interaction between two spatial frameworks:

The Earth Plate (地盘) represents the immutable substrate of reality. It consists of the twelve Earthly Branches fixed in their standard directional positions: Zi (North), Chou/Chen (Northeast), Mao (East), and so forth, arranged clockwise. This plate symbolizes the querent's current situation, the static environment, and earthly factors that cannot be immediately changed.

The Heaven Plate (天盘) represents the influx of celestial timing, opportunities, and external influences. It is generated by the 月将加时 procedure and rotates relative to the Earth Plate. When a divination is performed, the Heaven Plate shows how the current cosmic "weather" (the Monthly General) interacts with the specific moment of inquiry (the Hour).

Conceptually, imagine the Earth Plate as a fixed map of a city, while the Heaven Plate is a weather system moving over it. The "Adding Hour" technique positions the monthly weather pattern at a specific entry point (the hour), allowing diviners to see which cosmic influences affect which earthly sectors.

How It Works: The Calculation Method

The procedure follows a precise algorithm to transpose the Monthly Envoy onto the temporal framework:

1. Determine the Solar Month: Using the 24 Solar Terms (节气), identify the current solar month. For example, if the date falls between the Winter Solstice and the following solar term, you are in the Eleventh Month (Chou/Da Ji).
2. Identify the Monthly General (月将): Based on the solar month, select the corresponding General from the Twelve Monthly Generals table. For the Eleventh Month, this is Chou (丑).
3. Determine the Shi Chen (时辰): Convert the current time (adjusted for true solar time if necessary) into the appropriate double-hour Earthly Branch. For instance, 2:30 PM falls within Wei (未) hour.
4. Perform the Addition (加时): On the Earth Plate, locate the position of the Hour Branch (Wei). Place the Monthly General (Chou) onto this position. This is the "pivot point."
5. Rotate the Remaining Branches: Arrange the remaining eleven Earthly Branches clockwise around the Earth Plate, maintaining their standard sequential order. If Chou is placed on Wei, then the next branch in sequence (Yin) falls on Shen, Mao on You, and so forth, until all twelve positions are filled.
6. Finalize the Heaven Plate: The result is the Heaven Plate configuration for the divination, which remains static while the Earth Plate serves as the reference frame for deriving the Four Classes.

Worked Examples

Example 1: First Month, Noon Hour

Scenario: Divination performed during the First Month (after Li Chun 立春, the Beginning of Spring) at 12:30 PM.

• Solar Month: First Month → Monthly General: Hai (亥 / Deng Ming)
• Time: 12:30 PM → Shi Chen: Wu (午 / Noon)
• Setup: Place Hai on the Wu position of the Earth Plate
• Heaven Plate Configuration:
  • Wu position (Earth) = Hai (Heaven)
  • Wei position (Earth) = Zi (Heaven)
  • Shen position (Earth) = Chou (Heaven)
  • You position (Earth) = Yin (Heaven)
  • Xu position (Earth) = Mao (Heaven)
  • Hai position (Earth) = Chen (Heaven)
  • Zi position (Earth) = Si (Heaven)
  • Chou position (Earth) = Wu (Heaven)
  • Yin position (Earth) = Wei (Heaven)
  • Mao position (Earth) = Shen (Heaven)
  • Chen position (Earth) = You (Heaven)
  • Si position (Earth) = Xu (Heaven)

In this configuration, the Water element General (Hai) sits atop the Fire position (Wu), creating a complex elemental interaction (clash or restraint) that the diviner would interpret based on the Day Stem and specific question.

Example 2: Seventh Month, Dawn Hour

Scenario: Divination during the Seventh Month (after Qiushu 处暑) at 6:00 AM.

• Solar Month: Seventh Month → Monthly General: Si (巳 / Tai Yi)
• Time: 6:00 AM → Shi Chen: Mao (卯)
• Setup: Place Si on the Mao position
• Heaven Plate Flow: Mao=Si, Chen=Wu, Si=Wei, Wu=Shen, You=Chou, etc.

Here, the Fire Snake (Si) enters the Wood Rabbit (Mao) sector, generating a "Wood feeds Fire" productive cycle, suggesting growth and amplification in the reading.

From Setup to Divination: The Four Classes and Three Transmissions

The 月将加时 procedure is not merely an abstract exercise; it creates the essential framework for the subsequent calculation of the Four Classes (四课, Sì Kè) and Three Transmissions (三传, Sān Chuán).

Once the Heaven Plate is established:

1. The diviner notes the Day Stem (日干, Rì Gān) of the query date.
2. They locate where this stem appears on the Heaven Plate (its "heavenly" location) and its original position on the Earth Plate (its "earthly" residence).
3. These pairings generate four combinations (classes) representing: the self/querent, the object of inquiry, the environment, and the underlying factors.
4. From these Four Classes, the Three Transmissions are derived—a temporal sequence showing the development of the situation: the beginning (初传), middle (中传), and end (末传).

The Monthly General (Yue Jiang) selected during the 月将加时 process represents the Grand Timing or macrocosmic theme of the divination, while the specific hour (Shi Chen) represents the Immediate Timing or entry point of the inquiry into the cosmic flow.

Common Pitfalls

Practitioners, especially those new to Da Liu Ren, frequently encounter errors in the 月将加时 procedure:

• Solar vs. Lunar Confusion: The most critical error is using the lunar (moon-based) month instead of the solar month (based on the 24 Jie Qi). The Monthly Generals follow the sun's path, not the moon's phases.
• Standard Time vs. True Solar Time: Ancient Chinese timekeeping used sundials and clepsydra based on local solar noon. Modern clock time (standard time zones) may differ significantly from true solar time, especially in locations far from the time zone meridian or during daylight saving time. Advanced practitioners adjust the hour accordingly.
• The Zi Hour Boundary: The Zi hour (子时) begins at 11:00 PM, not at midnight. Divinations performed between 11:00 PM and midnight belong to the following day's stem-branch cycle, a subtle but crucial distinction.
• Rotation Direction: The Heaven Plate must always rotate clockwise (following the Earthly Branch sequence). Counter-clockwise placement inverts the entire reading.
• Confusing Yue Jiang with Tai Sui: The Monthly General (Yue Jiang) changes monthly and moves retrograde. The Tai Sui (太岁), or Grand Duke Jupiter, moves forward through the branches annually. These serve different functions in the divination.
