![]() It further continues to follow a lower and lower path through the sky (with the days getting shorter and shorter), the Sun reaches a point (called the Winter Solstice, occurring on December 21/22), after which it can't go any further lower.This point in the Sun's path occurs on September 22 and is called the Autumnal Equinox. On Summer Solstice (June 21), when the Sun is at its highest path through the sky and the day is the longest, it starts to follow a lower and lower path in the sky every day until it is there for about 12 hours in a day.Comparatively, the September equinox marks fewer events generally associated with autumnal harvest festivals.Ĭorrelation between the events of Solstice and Equinox:.This is the reason why many cultures celebrate the March equinox as the first day of the new year. The March equinox is regarded as the beginning of the spring season and is considered as the rebirth and renewal time.Marker of seasonal change: Like the solstices, equinoxes are the historical markers of seasonal change.For example, autumn and the autumnal equinox occur in the southern hemisphere in March, when it is spring in the Northern Hemisphere. The names are the opposite in the southern hemisphere because the seasons are switched.In the northern hemisphere the March equinox is known as the vernal equinox (vernal means fresh or new like the spring), while in September, it is known as the autumnal equinox.The two types of equinoxes that occur are March Equinox and September Equinox.This unique angle causes all the areas of earth or other planets to experience almost the same amount of daylight and darkness twice every year.This suggests that one half of the earth is still more lit than the other part, even on the day of an equinox. The earth’s atmosphere bends sunlight by 37 miles (approximately 60 km), which equals half a degree. The terminator does not divide the planet into dark and light. This results in the passing of the Terminator or Twilight Zone, which is a moving line that divides the illuminated side and the dark night side of the earth to pass through the earth’s north and south poles.Equator is an imaginary line on the middle of a planet or other celestial body.During this time, the sun is exactly above the earth’s equator.This phenomenon occurs two times a year, usually on March 20 th and September 22 nd.It is technically not a day-long astronomical event and being a day of equal daylight and night.astronomical spring in the southern hemisphere.astronomical fall season in the northern hemisphere.The September equinox, also called the Autumnal equinox, marks the beginning of the.Equinox is a point in a year when the daytime and night-time are approximate of equal lengths which are 12 hours each.This is known as the Fall Equinox or the September Equinox. On September 22, most of the Earth experienced about 12 hours of daylight and 12 hours of darkness. ![]() Good Practice - Examples & Case Studies.Workbook - Prelims/Mains Practice Questions.Mains Previous Year Question with Solutions New.2 Year Integrated (Pre-Cum-Mains) Test Series 2025.1 Year Integrated (Pre-Cum-Mains) Test Series 2024.IAS Prelims 2023: Yearly Current Affairs Revision Classes.GS Analyst: Weekly Current Affairs Classes.GS Mains Classes 2024 (Basic to Advance).
