It comes at 8:03 p.m in Mexico City and Chicago. However, it will be 1:04 UTC according to the Royal Museums Greenwich and the US National Weather Service.įor people in places such as Toronto and Washington, DC, that’s 9:03 p.m. The equinox will arrive at 1:03 UTC (Coordinated Universal Time) Friday, September 23, according to NASA and. The sun rises behind the Washington Monument in the US capital. Precisely when does the fall equinox happen? Here are the answers to some of your fall equinox questions:įrom our CNN Fast Facts file: The term equinox comes from the Latin word equinoxium, meaning “equality between day and night.” More on that farther down in the article. There’s a good explanation (SCIENCE!) for why you don’t get precisely 12 hours of daylight on the equinox. Well, there’s just one rub – it isn’t as perfectly “equal” as you may have thought. For people south of the equator, this equinox actually signals the coming of spring.įolks right along the equator have roughly 12-hour days and 12-hour nights all year long, so they won’t really notice a thing on September 22.īut during the equinox, everyone from pole to pole gets to enjoy a 12/12 split of day and night. If you reside in the Northern Hemisphere, you know it as the fall equinox (or autumnal equinox). On Saturday, we enter our second equinox of 2018. Give it a try - and, see below for spring-themed books to read with your child.Twice a year, everyone on Earth is seemingly on equal footing – at least when it comes to the distribution of daytime and nighttime. The feat simply takes the right egg, a little practice, and a lot of patience. Standing an egg on its end is something just about anyone can do any day of the year. There is no gravitational change during the equinox that would help an egg balance. The bottom line: This egg-balancing trick is just an old wives' tale. “This is why standing on two feet is easier than standing on only one foot.” “We stand upright by keeping our own personal centers of gravity within the bounds of our feet on the ground,” says Keller. You would not have time to balance your egg!"Ī balancing act: Is it possible to balance an egg in an upright position? The key is finding an egg with a yolk centered in the shell. “Even were there such a solar influence, it would only work in one place at a time, and that place would be moving at a speed on the surface of the Earth of about 1,000 miles per hour at the equator. The idea that an egg could balance on this day comes from the thought that since the Sun and Moon are equidistant from the earth, the pull of gravity is equalized and therefore an egg is less likely to fall over. The equinox, explained: The spring equinox occurs when the Earth is tilted parallel to its path of motion around the Sun, which makes the length of the day and the night exactly the same. Here, three things to know about the equinox and eggs: Keller, PhD, CEO of Smart Science Education Inc., for his scientific opinion. We wondered … is it really true? So we reached out to Harry E. Each season, this idea seems to pop up on the news, in social media, and in schools. Legend has it that on the spring equinox, you can balance an egg in an upright position thanks to the Earth’s position relative to the sun. ![]()
