The summer solstice in 2021

Long since the sun and length of daylight has a major impact on a person’s life, and we will tell you what number will be the summer solstice and when to celebrate the spring equinox in 2021.

Scientists have proven that many of the processes occurring in the Earth’s atmosphere and supports life on our planet is dependent on sun exposure. It is the position of the Earth relative to the main luminary of the Solar system familiar to us due to the change of seasons, the increase in air temperature in the summer months and cold periods in the winter, as well as the cyclical increase and decrease of daylight. How it works and why this is happening? Let’s try to understand

The sun is the basis of life

The sun is the basis of life on our planet. While in 149,6 million km from Earth, the Central luminary keeps its gravitational force for planets of the solar system, gives us the much needed warmth, light and energy. According to the calculations that made scientists, on average, 1 m2 of the surface of our planet receives in one day is about 342 Watts.

The importance of solar energy for plants and animals that inhabit the Land, speaks eloquently of the difference in number of species between the southern regions situated closer to the equator and receives plenty of sunshine and areas of Extreme North. Where there is the concept of polar night, and the temperature in winter sinks below -50ºC, are able to survive only a few instances that have adapted to the harsh conditions of the North. Thus, the amount of energy received by the surface of the planet, and the seasons of the year depend on the indirect motion of our planet around the Sun and its tilt angle.

The equinoxes and solstices what is the difference?

The importance of the sun is estimated with our ancestors. Even without knowledge of astronomy, they understood that it was daylight and the amount of heat sent by the Sun to the Earth, depends on productivity, and wellbeing. In many ancient cultures worshiped the Sun as the chief deity and celebrated 4 important events of the year:

  • Spring (summer) equinox – day and night are equal, but are in the process of gradual increase of daylight.
  • Summer solstice the longest day and the shortest night of the year.
  • Autumn (winter) equinox – day and night are equal, but are in the process of gradual reduction of daylight;
  • Winter solstice – the shortest day and the longest night of the year.
