Countdown Till Spring 2023 – The first day of spring is Monday, March 20, 2023, at 5:24 p.m. EDT. For those living in the Northern Hemisphere, this is marked by the arrival of the vernal equinox (otherwise known as the First Point of Aries).
Traditionally, we celebrate the first day of spring on March 21st, but astronomers and calendar makers now say that spring begins on March 20th in all North American time zones. Spring 2020 came on March 19, the first day of spring in 124 years!

Regardless of what the weather is doing outside, the vernal equinox marks the official start of spring. Get our official spring forecast.

So what does this mean?Basically, our daylight hours—the time between sunrise and sunset—gets a little longer each day starting with the winter solstice in December, the shortest day of the year (at least in terms of light).
Although we know that after December 21st, the days begin to get longer continuously, during the three months before and after spring, we see more darkness than light during the full sun. The vernal equinox marks the turning point when the sun begins to overcome the darkness.
At this time, the sun’s direct rays hit the equator, creating the effect of equal day and night (give or take a few minutes, see below). After the vernal equinox, the Sun’s direct rays move north of the equator (the hours of the day become steadily longer) until they finally reach the Tropic of Cancer (23.5 degrees north latitude).

The migration of direct sunlight stops on that day; This is the distance they travel north. This is what we call the summer solstice (
The migration of direct sunlight is continuous). It is the longest day of the year in terms of daylight hours.
After the summer solstice, direct rays move south and the sun begins to shorten. The fall equinox takes another three months to balance the periods of sun and darkness.

The ray eventually reaches the Tropic of Capricorn (23.5 degrees south latitude) on the winter solstice and the whole cycle begins again!
One question regarding the vernal equinox concerns the length of day and night. In the first days of spring and autumn, we teach that the length of day and night around the world is exactly 12 hours.
However, if you check the calendar pages in our almanac, you will see that this is not the case. In fact, our charts tell you that the length of daylight is several minutes longer than darkness on the vernal and autumnal equinoxes.

The reason for this can be attributed to our atmosphere. If Earth were a planet without an atmosphere, then yes, there would be equinoxes.
However, our atmosphere acts like a lens and refracts (bends) its light above the edge of the horizon. In other words, when you see the sun rising above the horizon at sunrise or setting below the horizon at sunset, you’re seeing an illusion—the sun is not really there, but below the horizon.
As a result, we actually see the Sun a few minutes before the Sun’s disc rises and a few minutes after it actually sets. Thus, due to atmospheric refraction, the length of daylight increases by about six or seven minutes in any given day.

Because the seasons are defined as starting at strict 90-degree intervals, these positional changes affect the time it takes to reach each 90-degree point in Earth’s orbit around the Sun.
Second, the gravitational pull of other planets also affects the position of the Earth in its orbit.
As you can see, the warm seasons of spring and summer are 7,584 days longer than the cold seasons, fall and winter (good news for warm weather lovers!).

However, currently spring is shortened by one minute per year and winter by one and a half minutes per year. Summer gains a minute lost from spring, and autumn gains half a minute lost from winter.
Winter is the shortest astronomical season and is expected to reach its lowest value of 88.71 days in about 3500 years as its seasonal length continues to shorten.
It returns to the elliptical orbit of the Earth as mentioned above. We are 3.1 million miles from the Sun (call
When Does Spring Begin?
) The closer a celestial body is to the Sun, the faster it must move in its orbit — gravity forces it, a fundamental natural law that astronomer Johannes Kepler proved 400 years ago. This means that during the colder months when we are closest to the Sun, we orbit faster through space. In July, when we are farthest from the Sun, we move slowly.

Although spring begins and ends at the same time in the Northern Hemisphere, the date and local time vary from place to place depending on the time zone of the location.

Spring, often called “spring”, is one of the four seasons that make up the year. It is the intermediate period between the coldest time of the year (winter) and the hottest time of the year (summer) and takes its name from the growth of new plants at this time: plants “spring”.
Astronomical Spring and Meteorological Spring There are different ways to determine the start and end dates of spring. The two most commonly used are based on the astronomical calendar and the meteorological calendar. Astronomical and meteorological spring begins and ends on different days.
Astronomical Spring The start and end dates of spring in the astronomical calendar are based on the Earth’s movement relative to the Sun and the solar events of the equinoxes and solstices. In the Northern Hemisphere, winter ends and spring begins at the March equinox, which occurs every year between March 19 and March 21. Spring ends and summer begins at the June solstice, which occurs every year between June 20 and June. 22. In the southern hemisphere, spring lasts from the September equinox (September 21-24) to the December solstice (December 20-23).

United kingdom). Although spring begins and ends at the same time in the Northern Hemisphere, the date and local time vary from place to place depending on the year and time zone. It may fall the following day for locations ahead of UTC (further east) and the previous day for locations behind UTC (west of west). Use this seasonal calculator to find the exact spring 2023 date and time in your area.
Meteorologists, on the other hand, define seasons based on climatic conditions and annual temperature cycles. It is important for them to compare the same period in different years. Astronomical seasons vary in length from 89 to 93 days, while meteorological seasons vary less in length and are fixed at 90 days for winter in non-leap years (91 days in leap years) and 92 days for spring. Summer and autumn are 91 days. Although the exact definition of the season’s timing and length may vary from region to region depending on local conditions, most meteorological spring in the Northern Hemisphere is generally defined as the three months of March, April, and May. March 1 and ends May 31.
There is no “official rule” for using spring, different countries follow different traditions. Most of North America and Europe use astronomical spring, while Australia and New Zealand use meteorological spring (although, because these countries are in the southern hemisphere, the seasons are opposite, with spring running from September to November). In other cultures, e.g. In the traditional Chinese calendar and Celtic tradition, the March equinox is considered the midpoint of spring.
