Just as we have small periods of time (months, seasons) in which nature changes and new influences come into dominance, there are also larger cycles about which humanity has yet to learn. Over centuries and aeons, there are celestial seasons.
On February 4–5, 1962, exactly when there was a new moon AND a full solar eclipse, there was also an extraordinary celestial conjunction of the seven primary planets with the Earth. The Sun, the Moon, Mercury, Venus, Mars, Jupiter, and Saturn were all within three degrees of each other, and aligned with the Earth.
This event signalled a change of era, similar to how the hands of a clock move into a new day. The Earth had completed an era under the influence of Pisces, and then entered an era influenced by Aquarius. Therefore, February 4 is New Year's Day in the Aquarian calendar.
"Our Aryan Root Race was born under the constellation of Aquarius, during the Era of the Water Carrier, immediately after the universal flood. Now the end of this Aryan Root Race is at hand because the voyage of our solar system has finished. It has returned after many years to its original point of departure due to the fact that in this precise moment we are in the Era of Aquarius again. This Era of Aquarius started again on the fourth of February of 1962 between two and three in the afternoon. At that moment, all the astronomers of the world could see with their telescopes the heavenly transit rush under the constellation of the Water Carrier. What we are asserting is perfectly documented. We are not affirming anything that does not have proper documentation. If someone states that the Age of Aquarius has not yet began, or affirms that it started sometime earlier than the date already mentioned, what does it matter to science or to us? The plain reality is that the Age of Aquarius started on the date already mentioned and that this phenomena was seen in all of the countries of the world by all of the scientists, astronomers, astrologers, etc. This scientific cosmic event is a concrete, official, and irrefutable fact. On that date, there was a solar and a lunar eclipse that some of you might remember. Therefore, cosmically speaking, only a few degrees are needed in order for the solar system, which is presently in Aquarius, to arrive exactly at the original point of its initial departure." - Samael Aun Weor, The Aquarian Message
