Equinox characteristics

Among its main characteristics are the following:

  • They are used as a point of reference in the field of astronomy .
  • It has also been used as an important religious and cosmological tradition .
  • It only occurs twice a year .
  • They indicate when spring and fall
  • When it occurs, the sun can be positioned exactly on the equator .
  • Day and night have the same duration , although this can vary.
  • In ancient times it was considered a symbol of fertility .
  • The day on which it occurs can perfectly change from one year to the next.

When it happens

The equinox happens twice during the year. The first date occurs between March 20 and 21 and the second date occurs between September 22 and 23 . These are the two moments in which the sun manages to reach the highest point.

Spring equinox

What does it consist of

It is known as the spring equinox when it occurs during the year where day and night have the same duration, this due to the position of the Earth’s axis related to the sun. This phenomenon makes it possible for the rays that come from the sun to affect both hemispheres in the same way. It is known for being the event that marks the beginning of spring . It is common that during this date the sun can be observed in a more perpendicular position on the Earth.

Date

This equinox takes place between days 20 and 21 March if you’re in the Hemisphere North and days 22 and 23 September when it is in the Southern Hemisphere . It only happens once a year in each of the hemispheres and when it occurs in one of the two hemispheres, the other then experiences the autumnal equinox.

Effects edit

During this important phenomenon, the days have a greater number of minutes with sunlight . Another effect which can be observed is that the sun rises a little early to the sunrise and manages to hide later. This means that in many places the hours have to be altered to increase productivity . The days gradually become a little warmer and nature begins to take on its traditional green color again.

Rituals

The vernal equinox has been seen through time as a moment in which fertility is celebrated and increases in all aspects, for this reason, hundreds of people around the world celebrate it. In Mexico , they usually gather around the Pyramid of the Sun to fill themselves with positive energies. In North India they celebrate the Holi Festival, a celebration where they celebrate the triumph of good over evil and the coming of a totally new cycle. In Bosnia they celebrate the Cimburijada when people gather on the banks of the Bosnia River to celebrate. In Australia the Floriade is celebrated.

Autumn equinox

What does it consist of

It is the moment that occurs during the year in which the day and night last the same amount of hours as the sun crosses the celestial equator of planet Earth. This is an astronomical event that indicates the change in the seasons to start enjoying the fall . It is the moment in which the Earth is located in a certain position allowing the rays that come from the sun to affect both hemispheres in the same way .

Date

This equinox happens only once a year in both hemispheres, in this way, in the Northern Hemisphere it happens between September 22 and 23, while in the Southern Hemisphere, the phenomenon occurs between March 20 and 21 .

Effects edit

Among the main effects that occur during this equinox, it can be mentioned that the days gradually become colder , the leaves of the trees gradually begin to fall and the rains and strong winds begin to be present . Many animals take advantage of this moment to be able to start collecting food and thus be prepared for winter and many of the birds begin their migratory trips to other warmer places to escape the cold winters.

Rituals

The arrival of the autumn equinox has been considered for years as the beginning of a time of transformation , reflection and planning and for this reason, in many places celebrations and rituals are held to celebrate its arrival. Many rituals are performed with the aim of finding harmony and balance in life. In many places observation and power walks are carried out in order to awaken the natural spirituality that the moment offers.

The collection of leaves, nuts and small roots to make an altar is also common in many places and is done to be able to give thanks for all the things that have been received during the year. Giving thanks is also a very practiced ritual, mainly for Andean cultures where they also celebrate an activity known as Pacha Poqoy Raymi .

How it differs from the solstice

The solstice is an event that occurs during the summer and winter, while the equinox occurs when spring and fall begin. During the solstice, the sun is positioned at the most distant point with respect to the equator, while at the equinox the sun’s rays reach the Earth with greater intensity, causing heat and light to arrive in the same way. .

During the solstice, the longest day of the year or the shortest day can be observed while the equinox, day and night have an equal duration . Finally, it is important to remember that the solstice is a phenomenon that can last several days , on the contrary, the equinox is an event that occurs at a certain point in time.

Importance of the equinox

Its main importance is given in the field of astrology because it represents a moment of positive change and greater balance and peace. For many cultures it is still a time of prayer and renewal, which is why it continues to be celebrated as an event of the utmost importance.
