Autumnal equinox meaning in hindi12/11/2023 The equinox date can change due to a variety of factors, including the leap year. In the case of the southern hemisphere, the opposite is true. The vernal equinox occurs in the Northern Hemisphere in March, while the autumnal equinox occurs in September. An equinox occurs when the plane of the earth’s equator passes directly through the geometric plane of the sun, implying that the centre of the visible portion of the sun falls directly over the equator. The Dates of Equinox are on March 20 and September 23. The Equinox is the time of year when the day and night are equal. Solstices and Equinoxes Diagramīelow are the diagrams of Solstices and Equinoxes: Solstices and Equinoxes Equinox Meaning 23rd of September is the Autumn Equinox while the 21st of March is Spring Equinox. This event is called equinox- meaning equal night. Neither the North Pole nor the South Pole is tilted towards the Sun, as a result of which, all the places on earth experience equal days and equal nights. The equator receives direct sunlight on March 21st and September 23rd. This event is called the Winter Solstice. The sun doesn’t set below the horizon at the Antarctic Circle. The sun’s rays fall vertically at the Tropic of Capricorn. On 22nd December, the Tropic of Capricorn receives direct rays of the sun as the South Pole is tilted toward the sun. This event is called the Summer Solstice. At the Arctic Circle, the sun never sets below the horizon. The northern hemisphere has the longest day on this day. For every place, above the Tropic of Cancer, the sun is at the highest point in the sky. On 21 st June, the Sun is vertical over the Tropic of Cancer. There would also be no need to mark the equinoxes or solstices. If the Earth were not tilted, the Sun would always appear directly above the Equator, the amount of light received at any given location would be constant, and there would be no seasons. This means that at different times of the year, different parts of the Earth receive more or less sunlight. Seasons change on Earth because the planet is slightly tilted on its axis as it orbits the Sun. The earth’s seasons are caused by equinoxes and solstices.
