  eSky: First Point of Aries
The First Point of Aries is not a fixed point in space: it moves along the Ecliptic at a rate of roughly one degree every seventy years.
The First Point of Aries is the point in the sky where the Celestial Meridian, the Celestial Equator and the Ecliptic all meet.
Astronomers use the astrological symbol for 'Aries', depicting the head and horns of a Ram, to indicate the point where the Ecliptic crosses the Celestial Meridian, known as the First Point of Aries.

 eSky: Aries
The First Point of Aries is a place of vital importance in the sky - here, the Ecliptic and the Celestial Equator cross, and when the Sun reaches this point, as it does once a year, the Vernal Equinox occurs.
The First Point of Aries also marks the Celestial Meridian, which is the zero-point for calculations of Right Ascension.
Because of the effects of precession on the Earth, though, the First Point of Aries moves through the sky, and in fact it left the constellation from which it takes its name in about the year 70 BC, when it entered the neighbouring constellation of Pisces.

Now, since the first point of Aries is distant six temporal hours from the mid-heaven above the earth, the times of that distance will be found, by multiplying the said six hours by the seventeen equatorial times of the horary magnitude of the first point of Gemini, to be 102.
Now, as it is required to bring the first point of Gemini, in its second position, to the mid-heaven, the whole distance is to be reckoned, viz.
And the first point of Gemini, on arriving at the ascendant, will be distant from the mid-heaven 102° 39' by right ascension; the 13th degree of Aquarius being then in culmination in the prescribed latitude.

 CATHOLIC ENCYCLOPEDIA: Reform of the Calendar
In the northern hemisphere the March equinox (or "first point of Aries") is called the vernal equinox; the September equinox ("first point of Libra"), the autumnal.
There were two main objects to be attained: first, the error of ten days, already mentioned, which had crept in, had to be got rid of; second, its recurrence had to be prevented for the future.
The first was attained by the omission from the calendar of the ten superfluous days, so as to bring things back to their proper position.

 Kalacakra Calendar
In the tropical zodiac, the first point of Aries is defined as the position of the Sun at the vernal equinox - at this point the plane of the Earth's equator and the ecliptic cross, and when the Sun is in that position in the Spring, day and night are of equal length.
Due to the phenomenon known as the precession of the equinoxes, the tropical first point of Aries is slowly moving against the background of the stars - the movement is at a rate of approximately 50 seconds of arc each year.
So, if the sidereal first point of Aries is defined for some hundreds of years ago, the Sun no longer actually crosses that same point, and as the years pass, is moving further away from it each time it passes by.

The sidereal first point of Aries or sidereal zero is defined as the point on the ecliptic diametrically opposite to the celestial (ecliptic) longitude line passing through the star Spica, which is the brightest star in the constellation Virgo and hence called α Virginis.
Starting from the sidereal first point of Aries, the circle of the ecliptic is to be divided into 12 30° segments (12 × 30 = 360) moving eastwards and those segments are called the sidereal zodiacal segments or raashi-s.
The sidereal first point of Aries is defined as the point 60° west of the point between Gemini and Taurus, or equivalently as the point 120° east of the point between Sagittarius and Scorpio.

Similarly, a Dec of +90 degrees points to the "North Celestial Pole" and -90 degrees points to the "South Celestial Pole." In this case, the word Celestial is used to distinguish between the North Pole in the sky and the North Pole on the Earth.
In the case of precession, the First Point of Aries really was in Aries when it was named around 0 A.D., but because of the slow shift in the orientation of the Earth's axis with respect to the rest of the galaxy, the First Point of Aries has since crept into the stars of Pisces.
The point to understand is that because of differences in the types of stars, size, and spectral class, the brighter star may be the one that is farther away.

Aries is seen as a ram, an animal prized by the nomadic tribes of the Middle East.
By 1800 B.C. because of the apparent shifting of the sky due to precession, the Sun came to be in Aries at the beginning of spring, which was true in Europe until the change from the Julian to the Gregorian calendar at the end of the 16th century.

 Equinox - Wikipedia, the free encyclopedia
More technically, the equinox happens when the Sun is at one of two opposite points on the celestial sphere where the celestial equator and ecliptic intersect.
The equinoxes are now the points where the equator intersects the ecliptic and the solstices the points on the ecliptic farthest away from the equator.
For astrology, at least the one derived from the ancient Greeks, the same thing holds true; the vernal equinox is the first point (i.e.

 KWTX | First Day of Spring: Vernal Equinox March 20, 2006
In astronomy, the vernal equinox (spring equinox, March equinox, or northward equinox) is the equinox at the beginning of spring in the northern hemisphere: the moment when the sun appears to cross the celestial equator, heading northward.
Considered as a time, rather than a point on the sky, the equinox occurs from March 19 to March 21, the precise time being about 5 hours 49 minutes later in a common year, and about 17 hours 26 minutes earlier in a leap year, than in the previous year.
The point where the sun crosses the celestial equator northwards is called the first point of Aries.

 The Astrophysics Spectator: Table-Basic Measures in Astronomy
Because the precession of Earth's rotation axis causes the first point of Aries to moves along the equator over time, the right ascension and declination of the stars change with time.
The equinoxes are the two points in the sky where the celestial equator and the ecliptic (the path in the sky that the Sun appears to travel along) cross.
The sun crosses the first point of Aries, or the vernal equinox, at the end of spring, and it crosses the first point of Libra, or the autumnal equinox, at the end of fall.

Aries, the constellation the Ram and the first sign of the zodiac, is the hot and dry sign and the night house of Mars (Confessio Amantis VII.989-992).
It is the starting point of the zodiac, since the sun enters Aries at the spring equinox--March 12 in Chaucer's day, March 21 in modern times--and creates excessive moisture and the rains of spring.
Aries is a northern sign; since it is also an eastern sign, it is an "obedient" one and obeys Virgo in the west, Astr II.28.27.

This point is not arbitrary, representing one of two points where the ecliptic, the Sun’s apparent path or the plane of the Earth’s path round the Sun, crosses the Earth’s equator.
The Draconic cycle is linked with the paths of the Moon and Sun, and the two points where the Moon’s path crosses the apparent path of the Sun, the ecliptic, which are called the Moon’s Nodes (the Moon’s orbit is tilted at an average of 5° with respect to the ecliptic).
The point where the Moon goes from south of the ecliptic to north of the ecliptic is called the Ascending or North Node and the opposite point the Descending or South Node, these are traditionally the Dragon’s Head and the Dragon’s Tail, respectively, and from this Dragon comes the adjective ‘draconic’.

Gradually, however, they drifted apart again, so that the equinoctial point has now moved through Pisces to the border with Aquarius; however it is still called the First Point of Aries, by astronomers as well as astrologers, and taken as the start of the Equinoctial or Tropical Zodiac.
It regards the rise of monotheistic religions with universal scope as a phenomenon of the new Age of Pisces, and the universal Christian church as the primary manifestation of the epoch.
Since the Solar Zodiac remains the measure of the religious cycles, the Solar gyre or cone remains the religious gyre whether the dispensation is primary or antithetical and the Lunar divisions mark the gyre of civilisation, whether it is primary or antithetical.
