其中太阳掌管10年，太阴掌管9年，土星为11年，木星12年，火星7年，金星8年，水星13年，北交点3年，南交点2年，加起来总共75年。其用法分日生与夜生盘两种不同顺序，

日生盘的顺序为：

•  金星（8）

•  太阴（9）

•  木星（12）

•  北交（3）

夜生盘顺序为：

•  土星（11）

•  火星（7）

•  南交（2）

• 金星（8）

Now that Birchfield has identified the original source, the controversy appears to be settled. The Moon's North Node rules ages 70-73 and South Node, ages 73-75 for all of us, whether we have day or night births.

Every individual's life then, has a period that is in the larger context ruled by Mars. How that period plays out depended on the factors Abu Ma'shar lists in the previous quote and I can recap simply as follows:

每个人的生命中，都有很大一部分由火星掌管，而那一段时间是如何演绎的，则可以根据以下ABU MA'SHAR大师列出的要点来分析：

Look at the age ruler in the nativity;

2. The house it is posited in

4. The testimonies of the other planets to it (aspects)

1. 所落入星座

3. 所主管的宫位（可以是多个宫位）

1. Its zodiacal condition

3. The house(s) it rules

然后看年份主管行星的情况：

2. 所落入宫位

4. 与其他行星所行程的相位

1. If both are good, it indicates great advantage and profit

3. If they do not agree in testimony, the ruler indicates only mediocre advantage and disadvantage; many ‘ups and downs’.

1. 如果两个象征性都良好，则喻示着优势和获利

3. 如果两个象征星表现情况不一直，则不好不坏，大部分情况会比较起伏不定

 

每个星限中又分副限，每个副限先从本限星依序轮值，每一副限掌管1/7的时间。例如，太阳限的第一副限由太阳开始轮值1.428571429年（10/7=1.428571429），第二副限为金星轮值1.428571429年，第三副限由水星轮值1.428571429年，依此类推，但南北交不再分副限。

需要特别注意的是，法达星限的用法依照目前残留下来的典籍，只有阿拉伯占星家阿布马夏（Abu Ma’shar）介绍的最为完整，以后的占星家大都依循他的用法，但用法上皆有若干不同。例如Bonatti就使用上述的用法，但若干占星家例如11世纪的Al-Biruni以及16世纪的Antonio de Montulmo就认为夜生盘的南北交点应该排列到最后。某些占星家例如16世纪的Joachim Camerarius甚至认为南北交点的限运应该去除。

目前美国的古典占星家也开始质疑法达副限的用法，例如Benjamin Dykes（Liber Astronomiae的译者）就质疑古典用法的正确性，他认为每个主限不应该平均七等分作为副限，而是应该要按照每颗轮值星所掌管的时程做不同的区分，例如太阳主限管十年，金星主限管8年，所以太阳主限下的太阳副限应该只能管10个月，接著就由金星轮值8个月，水星轮值13个月，依此类推，但南北交 不再分副限。

法达星限看流年的用法很简单，看该年由何星轮值主限与副限，再看该星在本命盘中所掌管的宫位，以及受剋与得吉程度，来断定该年的吉凶。法达星限不会单用，通常需要配合小限法，才能准确判断该年的吉凶以及吉于何事、凶于何事。用法详见其他案例。

南交的年限，对一个中年人来说是非常关键的

关于星体质的表现，有其他因素也需要被考虑的，

被凶星伤到否，是否靠近MC，HAYZ，等等。

例：

法达：日-土

掌管宫位：7宫

Kahlo was in the Firdar period ruled by the Sun and sub-period ruled by Saturn. The Sun is the Ruler and Almuten of the 1st house, (this house is associated with the life and the physical body of the native ‘Anatole’) and it makes an opposition to Mars, Almuten of the 6th house (this house is associated with diseases and defects of the body ‘Cace Tyche’). Saturn, the great malefic, is the Ruler and Almuten of the 7th house, active by Profection, and Ruler of the sub-period of Firdar, it is posited in the 8th house (this house is associated with death, fears and losses ‘Epicataphora’).

1925年 18岁与19岁

法达：水星-水星

主管宫位：7宫和8宫

KAHLO在1925年9月17日，被车辆严重撞伤，医生当时几乎判定无法生还

Firdar period and sub-period is ruled by Mercury. Considering Mercury as the Ruler and Almuten of the 2nd house and 11th house in her nativity, it would not point out this tragic episode in Kahlo's life. However, for being posited in the 12th house (this house is associated with serious diseases, hospitalizations, imprisonments and adversities ‘Cacos Daemon’) it shows the events very clearly. The Profected House by the time of the accident is the 7th house. The Ruler of the 7th house is Saturn, a planet that indicates limitations, which is posited in the 8th house (this house is associated with death, fears and losses) and it also is co-Almuten of the 6th house (this house is associated with diseases and defects of the body). When she was sick and using several plaster casts, the Profected House was the 8th house. The Ruler of the 8th house is Jupiter, conjunct to the cusp of the 12th house, mentioned above. Jupiter is a benefic planet by nature, but in the case of Kahlo's nativity in spite of being in Exaltation and Term, it is Cadent, Combust, and afflicted by an opposition from Mars and it is the Ruler of a bad house ‘Epicataphora’. Saturn, the co-Almuten of the 6th house, is posited in the 8th house.

1930: 22 years old

Profected House: 11th

主管宫位：11宫

In the beginning of the year, Kahlo interrupted her pregnancy due to the incorrect position of the fetus.

法达期间为水星-土星，两个行星根据上述情况，主导宫位为11宫，而其宫主星为水星，落于12宫。同样也是凶相。

Firdar: Mercury - Jupiter

1938: 31 years old

Firdar: Saturn - Jupiter and Saturn - Mars

Profected Houses: 7th and 8th

Kahlo spent nine months in the ABC Hospital, in Mexico City, where she was submitted to a total of 7 operations to the column. “I was sick during a year … I still am in a wheel chair and I don't know when I will be able to walk again. I have a plaster cast that, instead of being horribly boring, it helps me to better support my column. I don't feel pain, only a great weariness …, and, as it is natural, sometimes despair. An indescribable despair. However I want to live …”.

When Kahlo was submitted to the operations, she was in the Firdar of Saturn - Jupiter which had begun in 30-01-1949, entering the Firdar of Saturn - Mars in 26-08-1950. Saturn is the Ruler and co-Almuten of the 6th house (this house is associated with diseases and defects of the body), posited in the 8th house (this house is associated with death, fears and losses) and Jupiter, Ruler of the 8th house, posited in the cusp of the 12th house (this house is associated with serious diseases, hospitalizations, imprisonments and adversities). Mars, Ruler of the Firdar sub-period (26-08-1950), Almuten of the 6th house, makes an opposition with the Sun, Ruler and Almuten of the 1st house (this house is associated with life and with the physical body of the native). The Profected Houses during this disturbed period of Kahlo's life are the 7th and 8th houses. The 7th house is ruled by Saturn posited in the 8th house. The 8th house is ruled by Jupiter posited in the cusp of the 12th house, all these configurations were already delineated above.

1954: 47 years old
