![]() In other words, after Fall equinox 2023, the sun will start to move southward. Second, You can notice that the days are getting shorter and the nights are getting longer. I mean, the way your surrounding will become vibrant, can’t go unnoticed. First, you can see the sudden change in the color of the leaves around you. There are two ways to practically observe the northern hemisphere’s autumn equinox. Winter picks up pace after the arrival of fall in the northern hemisphere. Shorter Days Longer Nights in Northern Hemisphere Therefore, just for approximation, we simply say that during the vernal equinox and autumnal equinox, the length of day and night becomes equal. Moving ahead, in the light of equal day and night phenomena, I just want to clarify that it’s not exactly equal. In fact, it happens because of the sun’s passing over the Equatorial line. Don’t think that the earth’s axial tilt will become Zero during the equinoxes. In other words, we will have equal day and night i.e 12 hours. Hence, daylight and nighttime hours are equal. Or, you can say that on the eve of an equinox, the earth’s axis is neither tilted toward nor away from the sun. WHY? Because when the sun crosses over the imaginary celestial line, the earth’s tilt becomes perpendicular to the sunshine. We have equal days and nights during September Equinox (also during March Equinox). Illumination of Earth by the Sun on the day of the equinox (fall or spring). That’s why the September equinox is also known as the Southward Equinox. On the other hand, during the September equinox, the sun switches sides from the northern hemisphere to the southern hemisphere of the earth. That’s why the march equinox is also known as the Northward equinox. Well, the only difference between the march and September equinox is that during the march equinox, the sun switches sides from the southern hemisphere to the northern hemisphere of the earth. So, how to define March Equinox or even September equinox? OKAY, let me rephrase my question for you!!! What’s the difference between the march and the September equinox? Any Guess? These are the march equinox and September equinox. ![]() Moreover, you also know that there are two types of Equinox. September Equinox 2023 – First Day of Fall in the Northern HemisphereĪutumn season in Indian Union Territory Of Jammu and Kashmir/Credit: The StatesmanĪs you already know that an equinox occurs when the center of the sun appears to cross over the celestial equatorial line of the earth. On the other hand, due to the earth’s tilt, the equinox that occurs in September in the southern hemisphere is the Vernal or Spring Equinox. It marks the first day of winter, therefore, Winter Solsticeįrom the above comparison chart, it is clear that the equinox that occurs in September in the northern hemisphere is the Fall or Autumn Equinox. Marks the first day of spring, therefore, Spring Equinox. Marks the first day of autumn, therefore, Fall Equinox. It marks the first day of winter, therefore, Winter Solstice. It marks the first day of summer, therefore, Summer Solstice. In the southern hemisphere, it marks the first day of fall, therefore, Fall or Autumn Equinox. In the northern hemisphere, it marks the first day of spring, therefore, Spring or Vernal Equinox. Or, is the first day of fall in the northern hemisphere actually the official first day of fall or not? Therefore, in order to know that in detail, I would suggest you stick with me till the end. Moving ahead, in this article, we will talk about some of the exclusive facts like why there is a mismatch between the north and south equinoxes. CONFUSED? Don’t worry, we will talk about it in a later section. Regardless of the fact whether you are living in London (northern hemisphere) or Canberra (southern hemisphere), the length of the day and night are almost exactly equal on the eve of the Equinox. In other words, the meaning of the Equinox changes depending on the fact that at which side of the earth you live. On the other hand, for the people living in the southern hemisphere, this Equinox marks the arrival of the official first day of spring. In 2023, it will occur on Saturday, September 23, at sharp 06:50 Universal Coordinated Time (UTC). That’s why in the earth’s northern areas, the September Equinox is known as the Fall/Autumn Equinox. September Equinox marks the arrival of the first day of fall in the northern hemisphere.
