. The precise date of the Equinox varies from year to year but is always between 19 March and 21 March. The consequence is the start date of Aries and therefore the start date of all the other signs can change slightly from year to year. The following Western astrology table enumerates the twelve divisions of celestial longitude with the Latin names. The longitude intervals, are treated as closed for the first endpoint (''a'') and open for the second (''b'') – for instance, 30° of longitude is the first point of Taurus, not part of Aries. The signs are occasionally numbered 0 through 11 in place of symbols in astronomical works. The twelve signs are positioned in a circular pattern, creating a pattern of oppositions related to different philosophically polarized attributes. Fire and air elements are generally 180 degrees opposed in Western astrology, as well as earth and water elements. Not all systems of astrology have four elements, notably the Sepher Yetzirah describes only three elements emanating from a central divine source. Spring signs are opposite to autumn ones, winter signs are opposite to summer ones and vice versa. * Aries is opposite to Libra * Taurus is opposite to Scorpio * Gemini is opposite to Sagittarius * Cancer is opposite to Capricorn * Leo is opposite to Aquarius * Virgo is opposite to Pisces

as either positive or negative, with various attributes associated to them as a result. Positive polarity signs, also called active, yang, expressive, or masculine signs, are the six odd-numbered signs of the zodiac: Aries, Gemini, Leo,

, Scorpio, Capricorn, and Pisces. Negative signs make up the earth and water triplicities.

The three modalities

The modality or mode of a given sign refers to its position in the

, so practitioners of astrology describe it as having a cardinal modality. The combination of element and modality provides the signs with their unique characterizations. For instance, Capricorn is the cardinal earth sign, impressing its association with action (cardinal modality) in the material world (earth element).

Triplicities of the four elements

The Greek philosopher

identified fire, earth, air, and water as elements in the fifth-century BC. He explained the nature of the universe as an interaction of two opposing principles, love and strife, which manipulate the elements into different mixtures that produce the different natures of things. He stated all the elements are equal, the same age, rule their own provinces, and possess their own individual character. Empedocles said that those born with nearly equal proportions of the elements are more intelligent and have the most exact perceptions. The elemental categories are called triplicities because each

Dignity and detriment, exaltation and fall

A traditional belief of astrology, known as essential dignity, is the idea that the Sun, Moon, and planets are more powerful and effective in some signs than others because the basic nature of both is held to be in harmony. By contrast, they are held to find some signs to be weak or difficult to operate in because their natures are thought to be in conflict. These categories are Dignity, Detriment, Exaltation, and Fall. *

Dignity Dignity is a human's contentment attained by satisfying physiological needs and a need in development. The content of contemporary dignity is derived in the new natural law theory as a distinct human good. As an extension of the Enlightenment- ...

and Detriment: A

is strengthened or dignified if it falls within the sign that it rules. In other words, it is said to exercise '' Rulership'' of the sign. For example, the Moon in Cancer is considered "strong" (well-dignified). If a planet is in the sign opposite which it rules (or is dignified in), it is said to be weakened or in Detriment (for example, the Moon in Capricorn). This may also be termed a "debility"."Glossary of Astrological Terms". Logos, Asaa 1998–2004. 26 Nov 2007. In traditional astrology, other levels of Dignity are recognised in addition to Rulership. These are known as Exaltation, Triplicity, Terms or bounds, and Face or

, which together are known as describing a planet's '' Essential dignity'', the quality or ability of one's true nature. * Exaltation and Fall: A planet is also strengthened when it is in its sign of exaltation. In traditional horary astrology, this denotes a dignity just less than rulership. Exaltation was considered to give the planet's significance(s) the dignity of an honoured guest: the centre of attention but constrained in power. Examples of planets in their Exaltation are: Saturn (Libra), Sun (Aries), Venus (Pisces), Moon (Taurus), Mercury (Virgo, although some disagree with this classification), Mars (Capricorn), Jupiter (Cancer). A planet in the opposite sign of this is in its fall, and thus weakened, perhaps more than Detriment. There is discord as to the signs in which the two extra-Saturnian planets may be considered to be exalted. In addition to essential dignity, the traditional astrologer considers ''Accidental dignity'' of planets. This is placement by

in the chart under examination. Accidental dignity is the planet's "ability to act". So we might have, for example, Moon in Cancer, dignified by rulership, is placed in the 12th house it would have little scope to express its good nature. The twelfth is a cadent house as are the third, sixth and ninth and planets in these houses are considered weak or afflicted. On the other hand, Moon in the first, fourth, seventh, or 10th would be more able to act as these are Angular houses. Planets in Succedent houses of the chart (second, fifth, eighth, eleventh) are generally considered to be of medium ability to act. Besides Accidental Dignity, there are a range of ''Accidental Debilities'', such as retrogradation, Under the Sun's Beams, Combust, and so forth.

Additional classifications

Each sign can be divided into three 10° sectors known as decans or decanates, though these have fallen into disuse. The first decanate is said to be most emphatically of its own nature and is ruled by the sign ruler. The next decanate is sub-ruled by the planet ruling the next sign in the same triplicity. The last decanate is sub-ruled by the next in order in the same triplicity. While the element and modality of a sign are together sufficient to define it, they can be grouped to indicate their symbolism. The first four signs, Aries, Taurus, Gemini, and Cancer, form the group of personal signs. The next four signs, Leo, Virgo, Libra, and Scorpio form the group of interpersonal signs. The last four signs of the zodiac, Sagittarius, Capricorn, Aquarius, and Pisces, form the group of transpersonal signs."An Introduction to Astrology." Spiritsingles.com 25 Nov.2007. Dane Rudhyar presented the tropical zodiac primary factors, used in the curriculum of the RASA School of Astrology. The tropical zodiac is the zodiac of seasonal factors as opposed to the sidereal zodiac (constellation factors). The primary seasonal factors are based on the changing ratio of sunlight and darkness across the year. The first factor is whether the chosen time falls in the half of the year when daylight is increasing, or the half of the year when darkness is increasing. The second factor is whether the chosen time falls in the half of the year when there is more daylight than darkness, or the half when there is more darkness than daylight. The third factor is which of the four seasons the chosen time falls in, defined by the first two factors. Thus * The ''spring'' season is when daylight is increasing and there is more daylight than darkness. * The ''summer'' season is when darkness is increasing and there is more daylight than darkness. * The ''autumn'' season is when darkness is increasing and there is more darkness than daylight. * The ''winter'' season is when daylight is increasing and there is more darkness than daylight.

Indian astrology

In Indian astrology, there are five elements: fire, earth (land), air, water, and ether. The master of fire is Mars, while Mercury is of land, Saturn of air, Venus of water, and Jupiter of ether. Jyotisha recognises twelve zodiac signs (Rāśi), that correspond to those in Western astrology. The relation of the signs to the elements is the same in the two systems.
