![]() After the winter solstice, the Earth's axis begins to tilt back towards the Sun, and the days start to get longer. This means that the Sun appears to be at its lowest point in the sky. It is the day when the Earth's axis is tilted the most away from the Sun. The winter solstice is also a time of astronomical significance and marks the beginning of Astronomical Winter. This makes it both a time of celebration and reflection: a time to celebrate the return of the Sun and the promise of longer days ahead but also a time to reflect on the past year and to set goals for the year ahead. The winter solstice is the shortest day and longest night of the year after which the days begin to get longer and the nights get shorter. It is also only a few weeks from this time that the clocks go back marking the beginning of summer time and making the evenings draw in. As with the Spring Equinox this is a point of seasonal equilibrium with days and nights being almost exactly 12 hours long each. The Autumn or Fall Equinox signals the end of Summer on the astronomical calendar. This is the first day of Astronomical Summer and occurs as the sun reaches its most northerly or southerly path in the sky. The Summer Solstice is also known as the longest day, which is perhaps the most notable feature. It is around this time of year that the clocks go forward making the evenings stay light and marking the beginning of summer time. In fact the word equinox is taken from the Latin aequus (equal) and nox (night) or "equal night". It is also the point in the calendar where the day length is more or less equal to the length of the night.

On two days of the year, the Sun’s migration appears to come to a halt, and then it switches direction. What do the words solstice and Equinox mean?Įquinox and Solstice-What’s The Difference? Seasons According to Astronomy. The autumnal equinox occurs around September 22nd, when the sun crosses the celestial equator going south.Įven today, the spring, or “vernal” equinox is often used to indicate the first day of spring, but what it really signifies is the astronomical start of spring, as opposed to the meteorological one. In the northern hemisphere, the spring, or vernal equinox happens around March 21, when the sun moves north across the celestial equator. What does equinox Vernal and autumnal mean? Solstice, by comparison, takes place during winter and summer. In terms of the season where each phenomenon occurs, equinox takes place during the commencement of fall (autumn) and spring. This happens on September 22, 23, or 24 in most years. What is between solstice and Equinox?Īn equinox occurs when the sun is closest to the equator while solstice takes place at a time when the sun is at the furthest point from the equator. The September equinox is the moment the Sun crosses the celestial equator an imaginary line in the sky above Earth’s equator from north to south. Equinox comes from the Latin words aequi, which means “equal,” and nox, which means “night.” The vernal equinox is considered the first day of spring: finally, the day and night are of equal length. The vernal equinox marks the beginning of spring. These events are referred to as Equinoxes. The Equinox (Vernal & Autumnal) There are only two times of the year when the Earth’s axis is tilted neither toward nor away from the sun, resulting in a “nearly” equal amount of daylight and darkness at all latitudes. ![]() When the summer solstice happens in the Northern Hemisphere, the North Pole is tilted about 23.4° (23☂7´) toward the Sun. What happens on the summer equinox?Īt the summer solstice, the Sun travels the longest path through the sky, and that day therefore has the most daylight. ![]() Winter solstice (December 21 or 22): shortest day of the year, marking the start of winter. Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer.
