..    MARCH EQUINOX  ..       An equinox occurs when the center of the Sun is in the same plane as the Earth's equator,  when the tilt of the Earth's axis is inclined neither away from nor towards the Sun.     There are two Equinoxes,   a Vernal Equinox (vernal is Latin for "spring") and an Autumnal Equinox.     The Vernal equinox occurs around March 20th in the Northern Hemisphere   and around September 22nd in the Southern Hemisphere.     The Autumnal Equinox occurs around September 22nd in the Northern Hemisphere   and around March 20th in the Southern Hemisphere.     The Equinox in March is often referred to as the March Equinox   or Northward Equinox   while the Equinox in September is often called the September Equinox  or Southward Equinox to avoid the confusion of dates.         Translated from Latin,   equinox means "equal night."     Because the fact that the Sun is positioned above the equator,   day and night are about equal in length all over the world during the equinoxes.     Those two days are the only times during the year when the sunrise is due east and the sunset is due west.     The Equinoxes occur because of the 23.4 degree tilt of the Earth's axis.     Due to the tilt,   we receive the Sun's rays most dirctly in the summer.     In the winter,   when we are tilted away from the Sun,   the rays pass through the atmosphere at a greater slant,   bringing lower temperatures.         The Equinox is important in Religion.     In Christianity ..       Easter always falls on the first Sunday after the first full moon after the vernal equinox.     Jewish Passover usually falls on the first full moon after the Northern Hemisphere vernal equinox ..       Early Egyptians built the Great Sphinx so that it points directly toward the rising Sun on the vernal equinox ..       The first day of spring also marks the beginning of Nowruz, the Persian New Year ..       The celebration lasts 13 days and is based on the 3,000-year-old tradition of Zorastrianism.     Stonehenge (Celtic) in England also marks the position of the rising sun on the vernal equinox ..           ..    BAHAI NAW-RUZ  ..       Bahá'í Naw-Rúz,   also known as Bahai Calender New Year,   is The end of the 19-day sunrise-to-sunset fast in the Bahá'í Faith.     This is the first day of the Bahá'í calendar occurring on the vernal equinox,   around March 20th (It could be any day from March 20th to March 22nd).     Since Bahá'í days start at sundown and Bahá'í Naw-Rúz occurs on the day on which the vernal equinox occurs,   if an equinox occurrs before sunset,   then Naw-Rúz is celebrated on the day wthat started with the previous sunset.     It is celebrated primarily in the Middle East and Central Asia,   especially in Iran ..     Azerbaijan ..     Afghanistan ..     and Tajikistan ..           ..    NOWRUZ  ..       Persian (Iranian) New Year's festival of Nowruz (Iranian diaspora, Kurdish diaspora, Zoroastrians).     Nowruz is marks the first day of spring and the beginning of the year in Iranian calendar.     It is celebrated on the day of the astronomical Northward equinox,   which usually occurs on March 20th,  March 21st,  or March 22nd;
