if u can find a star in a particular location in a certain day at a specific time in night , then u can find the same star in nearly the same location at night at the same sidereal time:provided the observation point remains the same.
therefore vernal equinox helps to track the direction of a given star in the sky.

What are other names for fall equinox?
It used to be called "The First Point of Aries", because it was located just inside the constellation Aries. However, due to precession the 'point' shifts over time.

Does the date of the equinox vary?
Any calendar is a man-made idea; so is the idea of "date". There are a number of calendars commonly used throughout the world, and unless the calendar is adjusted to FORCE the vernal equinox to occur on a certain date, then yes, the "date" of the vernal equinox will vary.
Why do you have zodiac?
The constellations associated with the zodiac signs are in a belt formation around the Earth on the celestial sphere. They were originally used to forecast the influence they had on events and people on Earth; especially the seasons. In the northern hemisphere the Sun entering Aries occurs with the Vernal / spring equinox. the start of spring. The Sun entering Cancer with the summer solstice; Sun entering Libra with the autumn equinox and the Sun entering Capricorn the winter solstice. Due to the precession of the equinoxes the zodiac signs and the constellation no longer align; the Sun is now in the constellation Pisces when it enters the zodiac sign Aries at the vernal equinox.
How old is the Sphinx?
The vernal equinox is the beginning of spring, a day important in many cultures as it marked the beginning of spring. The Sphinx faces East where the Sun rises on the day of the vernal equinox (21 March). Currently vernal equinox is in the constellation of Pisces the Fish. The precession of the equinoxes takes about 25,000 years to go through all of the constellations. The vernal equinox 10,500 BC was the constellation Leo - the Lion. Professor of geology Robert M. Schoch found geological evidence to suggest that the deep erosion patterns at the base of the Sphinx were caused by water and not by wind and sand erosion as was commonly believed. Professor Schoch’s conclusions suggested that the Sphinx dated at least 9000 B.C - 10,000 BC when Egypt had long rainy periods after the end of the last Ice Age. However, upon further research, it was found that the most important day in ancient Egypt was the summer solstice, not the vernal equinox. Why? The annual flooding of the Nile occurs shortly after the summer solstice. In fact, the ancient Egyptians divided their calendar into three seasons: flood, seed, and harvest. Four seasons are marked by summer solstice (longest day), winter solstice (shortest day), spring equinox(midway between summer and winter solstices, and autumnal equinox. Four seasons do not mesh with three, therefore, spring equinox was probably not even used (feel free to modify). Finally, the precession of the equinoxes puts Leo at summer solstice just before sunrise when Ra (sun) replaced Leo in the sky about 4000 B.C. not 10,500 B.C., 6000 years ago - not 12,500. Carbon dating of materials found in the cracks of the Sphinx showed an age of about 5000 years. I find this not to be inconsistent as a new sphinx would be unlikely to have cracks to put things in.3,500 years old
Day and night are equal at?
Equal periods of sun-up and sun-down are all near March 21 and September 21, everywhere on earth, including the equator. Those days are often called the "equinoxes", but the equinoxes are actually the points in the sky where the sun appears to be located on those days.
What is used to calculate the date for Easter?
Easter falls on the 1st Sunday after the 1st full moon after the spring equinox which is March 20thI think it is the first Sunday after the first full moon after the first day of Spring (the spring equinox).
What is the right ascension of the earth?
"Right Ascension" is a coordinate in one of the main celestial coordinate systems. It is measured eastward along the "celestial equator". The units of measurement are hours, minutes and seconds. Those units are used because the "celestial sphere" appears to rotate once each day. Each hour is the equivalent of 15 degrees. The zero or starting point for right ascension is the "Vernal Equinox". It may seem odd to refer to the Vernal Equinox as the starting point of a coordinate system. The Vernal Equinox is actually a point in space. This point in space is occupied by the Sun at the time we call the Vernal Equinox. You can think of Right Ascension as being the equivalent of the Earth's meridians projected out into space.
Why do we get Easter holiday?
Although Christians use Easter as a ceremony of "spiritual" rebirth the festival was originally a vernal equinox celebration of Northern European peoples to celebrate the return of life to the world after winter. The fertility symbols of eggs and rabbits were used as symbols of fecundity in these rites. They used the name or avvarient of Ä’ostre or Ostara. The Christians borrowed the time of year, name and symbols of the old festival.
How did ancients know the Sun was in zodiac sign?
The ancients (especially the Egyptians) used the stars to to tell time. The Egyptians used 36 stars to mark the year. They also noticed the Precession of the Equinox, the occasion of the sun rising in due east. They named the stars fields the sun passed through and called them Ages or Eons, e.g. the Age of the lamb, the Fish and the coming Waterman(Aquarius). The Temple at Denderah contained a Zodiac.
Why does America not have the union jack on their flag?
because they attained independence from the british and decided to establish their own flag (although the union jack used to be part of the flag, instead of stars)
Why is Easter never celebrated on the same date?
Because the christians stole it from the pagans. It used to be a pagan festival, and the pagans worshipped all sorts of stuff - the date of Easter is set according to when the full moon appears, its something like the second Sunday after the full moon in March.
