New millennium astrological chart
Aries (♈) // (meaning "ram") is the first astrological sign in the zodiac, spanning the first 30 degrees of celestial longitude (0°≤ λ <30°). Under the tropical zodiac, the Sun transits this sign mostly between March 21 and April 20 each year. This time duration is exactly the first month of Solar Hejri calendar (Farvardin). Under the sidereal zodiac, the sun currently transits Aries from April 15 to May 14 (approximately). The symbol of the ram is based on the Chrysomallus, the flying ram that provided the Golden Fleece.
According to the tropical system of astrology, the Sun enters the sign of Aries when it reaches the northern vernal equinox, which occurs around March 21. Because the Earth takes approximately 365.25 days to go around the Sun, the precise time of the equinox is not the same each year, and generally will occur about 6 hours later each year, with a jump of a day (backwards) on leap years. Since 1900 the vernal equinox date has ranged from March 20 at 08h (2000) GMT to March 21 at 19h (1903) GMT. March 19 at 23:20 will occur in 2044 UT1.
Individuals born between these dates, depending on which system of astrology they subscribe to, may be called Arians or Ariens.
Aries is a sign of initiative; a leader, with bravery, and the autonomy required to commence. Uncomfortable with inaction, Aries is the Cardinal sign of Fire, and thus is the zodiac of drive. Ruled by Mars, Aries is strongly autonomous, and can be headstrong and crass, sometimes showing an impulsive or reckless approach to issues. With the Ram as their standard, Aries tends toward obstinate and self-seeking. Jaunty and self-supporting, Aries is capable of independence. This quality may encourage others to emulate—but Aries is unlikely to pause for supporters. When Aries is found in a chart, there is enthusiasm and decisiveness.
