Spring equinox 2021 images11/29/2023 The equilux, meaning ‘equal light’, occurs a few days before the spring equinox and a few days after the autumn equinox.ĭuring the equilux, the disk-shape of the sun is factored into calculations and the result is a perfectly balanced day of 12 hours of light and 12 hours of dark.Īfter the event, the Earth’s axis tilts the northern hemisphere towards the sun, giving us longer and warmer days and providing the ingredients for a splendid British summer. Yet there is a day when the whole world can experience equilibrium, which is known as the ‘equilux’. However, because of the disk-like shape of the sun and the way it gradually rises above the horizon revealing the top first, the day of the spring equinox actually sees 12 hours and 10 minutes of sun and not an equally distributed 12 hours. This phenomenon occurs because the Earth’s axis is perpendicular to the sun’s rays. On the day of the equinox, the length of day and night is in principle exactly the same for the entire world. It means ‘equal night’ - aequus (equal) and nox (night). The word ‘equinox’ comes from, as you might have guessed, a Latin term. The season will continue all the way until the summer solstice, which takes place on Tuesday, June 21, 2022. It is also important to note that the clocks go forward by an hour at 1am on the 27th March, one week after the equinox, which will give Britons even more time in the sun. The vernal or spring equinox marks the first day of astronomical spring this year, it falls on Sunday, March 20 in the northern hemisphere. These seasons revolve around equinoxes and solstices. When is the Spring Equinox in 2022?Īstronomical seasons are determined by the Earth's tilt as it orbits the sun. This event has long been celebrated in the northern hemisphere as a time of rebirth and is an important component in various spring-time festivals such as Easter and Passover. The March equinox, also known as the spring or vernal equinox, is a watershed astronomical event that occurs every year and signifies the start of the new season.įor those in the southern hemisphere, the March equinox marks the beginning of autumn. It is also the time of the year in which the Northern and Southern Hemispheres are distributed equal amounts of light.It’s been a cold and blustery winter across the UK, and while the chilly weather will continue for a while longer, Britons will take relief in the arrival of the March equinox, signalling warmer weather, longer days and the many blooms of spring. An equinox happens twice a year when the sun is positioned directly above the equator making day and night approximately equal in length which is why in Latin, equinox means “equal night.” The reason we have seasons is due to the fact that the earth is tilted on an axis toward the sun. Remind me what an equinox is again? Image from Shutterstock This year the spring Chicagohenge will be best experienced on the official first day of spring which is Monday, March 20th. Dubbed “ Chicagohenge“, twice a year for the spring and fall equinoxes the sun lines up directly with Chicago’s streets and beams down the heart of the city splashing through Chicago’s artificial valleys. In Chicago, the equinoxes provide a similar sight right here in our urban metropolis. During the summer and winter solstice, the sun rises behind Stonehenge’s Heel Stone, where its rays are captured within the rock frame, creating a glorious spectacle that thousands of people flock to witness You’re likely familiar with the prehistoric boulder formation in Wiltshire, England. One of Chicago’s most unique experiences returns this month offering an extraordinary collaboration between the magic of nature and Chicago’s glorious architecture during the spring equinox.
