The Four Seasons (Italian: Le quattro stagioni) is a set of four violin concertos by Antonio Vivaldi. The texture of each concerto is varied, each resembling its respective season.

Notes and Historical Information The Four Seasons (Le quattro stagioni) consists of four concerti (Spring, Summer, Autumn, and Winter), each one in a distinct form containing three movements with tempos in the following order: fast-slow-fast.

Meteorologists recognize spring as spanning March, April and May for consistency’s sake in weather record-keeping and also based on temperature trends in the U.S. Astronomical spring will officially begin at the vernal equinox, which will occur at 5:37 a.m. EST on March 20, 2021.

So, in the Northern Hemisphere you have:

• Vernal equinox(about March 21): day and night of equal length, marking the start of spring.
• Summer solstice (June 20 or 21): longest day of the year, marking the start of summer.
• Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn.

While the solstices result in a change of the length of night and day, the equinoxes do not. The summer and winter solstices result in the longest and shortest day of the year respectively while the equinoxes result in an equal amount of daylight and darkness received all across the earth.

The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth’s orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it’s at the closest distance from the equator.

There are two times each year, in March and September, when the amount of daylight and darkness is “nearly” equal at all latitudes. This phenomenon, commonly referred to as an equinox, happens when the Earth’s axis is tilted neither toward nor away from the sun.

The equinox is defined as a day that occurs twice per year when the sun crosses the equator and the night and day are the same length. A day in March that is the beginning of spring and a day in September that is the beginning of fall, are examples of the equinox.

Twice a year, the sun crosses the celestial equator, moving from the Northern Hemisphere to the Southern Hemisphere, or vice versa. These two crossings are very important for the inhabitants of Earth, because they mark the change in the direction the sun’s rays fall on Earth.

During an equinox the earth’s north and south poles are not tilted towards or away from the sun and the duration of daylight is theoretically the same at all points on the earth’s surface. Hence the name, equinox, which is derived from the Latin meaning equal night.

At a deeper spiritual level, according to the Conscious Reminder Blog, the equinox is thought to represent: “the period of struggle between darkness and light, death and life. It occurs when the night and day will be equal, and the journey of the Sun to actually get there also signifies the journey of the Universe.
