5 curiosities about autumn

1. The autumnal equinox is not always the same day

Like the vernal equinox, the autumnal equinox is not always the same day. And what is an equinox? It is about the moment when the Sun is located at the equator and the duration of day and night is the same throughout the planet. In the northern hemisphere the spring usually takes place on March 20 or 21 and the fall on September 22 or 23. This year 2021 the astronomical autumn will begin on September 22 at 9:20 p.m. The climatological autumn is measured by complete months and would cover September, October and November.

2. The harvest moon

The full moon closest to the autumnal equinox is known as the harvest moon. The allusion to the harvest is because it is brighter, so farmers could work late. This designation dates back to 1700. “In the days before electric lights, farmers throughout the Northern Hemisphere relied on bright moonlight to extend the workday beyond sunset,” NASA said in a statement. “It was the only way they could pick their mature crops in time for the market.” The harvest moon generally refers to the September full moon, although if the October full moon is nearing the date, it is this that takes the title. In 2021, the harvest moon took place on September 20.

3. Those born in autumn are longer-lived

A study conducted by scientists at the University of Chicago and published in the Journal of Aging Research concluded that people born in the fall have a greater chance of reaching 100 years of age . The truth is that there are more factors that make a person live more or less years, such as their eating habits, exercise, alcohol consumption, tobacco, the conditions they may suffer, the place where they live … However, this work He discovered that the month in which we were born also had to do with whether we were more or less long-lived. The study found that 30% of American centenarians born between 1880-1895 were born in the fall months. As for the months with the lowest life expectancy, March, May and July produced 40% fewer centenarians. Data from 1,500 people born between 1880 and 1895 were analyzed.

4. Squirrels work hard in the fall.

Squirrels have a lot of work to do in the fall and they have to gather their food for winter . They collect nuts and seeds and bury or hide them in their nests. According to a 1998 study, squirrels never find all the nuts they store during the fall. Up to 74% of them can remain hidden.

5. Many animals go into heat

In the same way that happens to humans, since it has been proven that autumn is when testosterone levels rise and commitments increase, for other animals the moment of courtship begins. A clear example is the bellowing , between September and October, in which male red deer relentlessly emit guttural sounds to attract females and mate.
