When Does Spring 2023 Start – Spring 2023 begins on Monday, March 20, 2023 (in 47 days) and ends on Wednesday, June 21, 2023 (in 140 days). Calendar for 2023
Please note: The dates provided on this page are based on Coordinated Universal Time (UTC), which for practical purposes is equivalent to Greenwich Mean Time (GMT). Since spring begins and ends at the same time throughout the Northern Hemisphere, local dates and times vary from place to place depending on a place’s time zone. For more details, see the explanation below.
When Does Spring 2023 Start
Spring, also often called “spring,” is one of the four seasons that make up the year. It is the period between the coldest time of the year (winter) and the hottest time of the year (summer) and gets its name from the growth of new plants during this time: the “bud” plant.

Astronomical Spring vs. meteorological spring There are different ways to define the start and end dates of spring. The two most used are based on the astronomical calendar and the meteorological calendar. The astronomical and meteorological spring begins and ends on different dates.
Astronomical Spring In the astronomical calendar, the start and end dates of spring are based on the change in the Earth’s position relative to the Sun and the resulting solar events of the equinoxes and solstices. In the Northern Hemisphere, winter ends and spring begins at the time of the Martian equinox, which occurs every year between March 19 and 21. Spring ends and summer begins at the time of the June solstice, which occurs every year between June 20 and 22. In the southern hemisphere, spring runs from the September equinox (September 21-24) to the December solstice (December 20-23). ).
The spring start and end dates shown on this page are the astronomical dates for spring in the northern hemisphere and are based on Coordinated Universal Time (UTC), which for practical purposes is Greenwich Mean Time (GMT, British time zone). . Since spring begins and ends at the same time throughout the Northern Hemisphere, local dates and times vary from place to place depending on the year and time zone. For locations ahead of UTC (further east) it may fall the next day, and for locations behind UTC (further west) it may fall the day before.

Spring Weather Meteorologists, on the other hand, define the seasons based on weather conditions and the annual temperature cycle. It is important to be able to compare the same time period in different years. The duration of the astronomical season varies from 89 to 93 days, while the duration of the meteorological season is less variable and is fixed at 90 days for winter in a non-leap year (91 days in a leap year), 92 days for spring. and summer, and 91 days for fall. While the exact definition of weather and the length of a season can vary in different areas depending on local conditions, the meteorological spring in most of the Northern Hemisphere is generally defined as the three months of March, April, and May, and the season starts on 1 more. and ends on May 31.
There are no “official rules” as to which definition of spring to use, and different countries follow different conventions. Most of North America and Europe use the astronomical spring, while Australia and New Zealand use the meteorological spring (but since these countries are in the southern hemisphere, the seasons are opposite of spring, which lasts from September to November). . In other cultures, e.g. In the traditional Chinese calendar and in Celtic tradition, the March equinox is considered to be approximately mid-spring.

For those of us in the Northern Hemisphere, this was marked by the arrival of the Vernal Equinox (also known as the “First Point of Aries”).

Traditionally, we celebrate the first day of spring on March 21, but both astronomers and calendar makers now say that spring begins on March 20, in all North American time zones. In 2020, spring fell on March 19, the first day of spring in 124 years!
No matter what the weather is like outside, the vernal equinox marks the official start of spring. Find our official spring announcement.
So what does this mean? Essentially, our daylight hours, the daily period of time between sunrise and sunset, have gotten a little longer each day since the winter solstice in December, which is the shortest day of the year (at least in terms of daylight). .
When Does Spring Start?
Although we know that the days after December 21 start to get longer and longer, we still see more darkness than light in one day during those three months until spring. The spring equinox marks the turning point when daylight begins to prevail over darkness.
At this time, the direct rays of the sun shine on the equator and produce equal effects day and night (give or take a few minutes, see below). After the vernal equinox, the sun’s direct rays travel north of the equator (with gradually increasing daylight hours) until they finally reach the Tropic of Cancer (latitude 23.5 degrees north).
The migration of the direct rays of the sun stops on this day; this is as far north as they will go. We call this the summer solstice (

It is a suspension of the migration of the direct rays of the sun). It is the longest day of the year in terms of daylight hours.
After the summer solstice, the direct rays continue south and the days begin to get shorter. It will take another three months, until the autumnal equinox for the period of day and darkness, to reach equilibrium again.
The rays finally reach the Tropic of Capricorn (latitude 23.5 degrees south) on the day of the winter solstice, and the whole cycle begins anew.

A question about the vernal equinox asks about the length of the day in relation to the night. They taught us that the first days of spring and autumn are day and night equal to exactly 12 hours all over the world.
However, if you review the calendar pages of our almanac, you will find that this is not the case. In fact, our tables tell you that on the days of the spring and fall equinoxes, the length of daylight is actually longer than darkness by several minutes.
The reason this happens can be attributed to our atmosphere. If Earth were a planet without an atmosphere, then yes, at the equinoxes the length of day and night would be exactly the same.

However, our atmosphere acts like a lens and refracts (bends) light over the edge of the horizon. Put another way, when you see the sun rise above the horizon at sunrise or set below the horizon at sunset, you are looking at an illusion: the sun is not really there, but is already below the horizon.
As a result, we end up seeing the Sun a few minutes before the disk rises and a few minutes after it sets. Thus, thanks to atmospheric refraction, the length of daylight on any given day is increased by about six or seven minutes.
Since the seasons are defined as starting at strict 90 degree intervals, these position changes affect the time it takes for Earth to reach each 90 degree position in its orbit around the Sun.

Second, the gravitational pull of other planets also affects Earth’s position in its orbit.
As you can see, the warm seasons, spring and summer, are a total of 7,584 days longer than the colder seasons, fall and winter (good news for fans of warm weather!).
However, spring is now reduced by about one minute per year and winter by about half a minute per year. summer has
