When Do Summer Start 2023 – When do the four seasons – spring, summer, autumn and winter – begin in 2023? Here are answers to common questions about the equinox, solstice – and the seasons in North America. (Do you know which season is too short?)
Many people assume that the four seasons occur when the earth is closer to the sun (so it is warmer) in summer and further away from the sun (so it is colder) in winter. This is wrong.
When Do Summer Start 2023
Seasons are caused by the tilt of the Earth’s axis. In fact, winter is when the Earth is closest to the Sun (and vice versa). More on that in a moment.

Our year (12 months) is usually divided into four seasons each lasting three months (but strictly speaking).
Season start and end dates vary depending on who you ask. Each season has an astronomical beginning and a meteorological beginning. It sounds complicated, but trust us, it’s not!
Note: The above dates correspond to the beginning of the seasons listed in the Northern Hemisphere. Times are based on Eastern Time (ET). 3 hours Pacific Time, 2 hours Mountain Time, 1 hour Central Time, remove immediately.

Our book has long followed the astronomical “calendar of the heavens”, hence the astronomical definition of the seasons based on the sun and the earth!
As mentioned at the beginning of this article, the tilt of the Earth’s axis causes the seasons. The axis is always bent in the same direction. Therefore, as the Earth orbits the Sun for 12 months of the year, different parts of the Earth receive the Sun’s direct rays.
See the diagram below. When the North Pole tilts towards the sun, it is summer in the Northern Hemisphere. When the South Pole is tilted towards the sun, it is winter in the northern hemisphere.

You may have noticed a different date on the first day of spring than when you were younger. Dates actually change over time. There are many reasons for that, but one that is easy to understand: The sun does not follow the human calendar!
Our Gregorian calendar is designed to match the time it takes the Earth to orbit the Sun, which is inaccurate. In particular, it eliminates century leap days that are not evenly divisible by 400, such as 1700, 1800, and 2100, and millennium leap days that are divisible by 4000, such as 8000 and 12000.
Therefore, the dates of the equinoxes and solstices can shift by a day or two over time, causing the start dates of the seasons to shift over time as well.

Winter can sometimes seem to last forever, but did you know that winter is actually the shortest season of the year? (In the northern hemisphere, that is.)
Why is the Earth not at the same distance from the Sun all year round thanks to the elliptical shape of the Earth’s orbit around the Sun? In January we reach the closest point in our orbit to the Sun (called perihelion), and in July we reach the farthest point (aphelion). Read more about perihelion and aphelion.
As Earth moves closer to the Sun, the star’s gravitational pull is slightly stronger, causing our planet to move slightly faster in its orbit. For those of us in the Northern Hemisphere, this leads to a shorter fall and winter because we are moving faster through space at that time of year. Conversely, when the Earth is further from the Sun, it moves more slowly, resulting in longer spring and summer seasons. (The opposite is true in the southern hemisphere.)
When Do The Seasons Start And End In 2023?
In other words, it takes less time for the Earth to go from autumnal equinox to spring equinox than it does to go from spring to autumnal equinox.
What defines each season? Below is a brief description of the four seasons in calendar year order. For more information, link to indicated equinoxes and solstices.
At the vernal equinox, day and night are each about 12 hours long (in the Northern Hemisphere, the real-time equivalent of night and day occurs a few days before the vernal equinox). The sun crosses the celestial equator and goes north; It rises in the east and sets in the west. Check out our first spring day page.

During the summer solstice we enjoy the longest daylight of the calendar year. The sun reaches its northernmost point in the sky (in the northern hemisphere) at local noon. After this date, the days begin to “shorten”, that is, the length of the day begins to decrease. Check out our first summer day page.
At the autumnal equinox, day and night are each about 12 hours long (in the Northern Hemisphere, day and night are of equal length a few days after the autumnal equinox). The Sun crosses the celestial equator and moves south; It rises in the east and sets in the west. Check out our first autumn day page.
The winter solstice is the “shortest day” of the year, meaning the least sunlight. The sun reaches its southernmost point in the sky (in the northern hemisphere) at local noon. After this date, the days begin to get “longer”, that is, daylight begins to increase. Check out the first winter day page. Summer 2023 begins on Wednesday, June 21, 2023 (in 154 days) and ends on Saturday, September 23, 2023 (in 248 days). Calendar 2023

Please note: Dates given on this page are based on Coordinated Universal Time (UTC), which is equivalent to Greenwich Mean Time (GMT) for practical purposes. While summer begins and ends at the same time across the Northern Hemisphere, the date and local time varies from place to place depending on your time zone. See the descriptions below for more information.
Summer is one of the four seasons that make up the year. It is the warmest time of the year, which falls between spring and autumn (autumn), and the periods leading up to and after winter, the coldest time of the year.
Astronomical summer vs. Meteorological summer There are different ways of defining the start and end dates of summer. The two most commonly used are based on the astronomical calendar and the meteorological calendar. The astronomical and meteorological summer solstices begin and end on different dates.
Calendar Of Classes
Astronomical Summer The start and end dates of summer in the astronomical calendar depend on the Earth’s changing position in relation to the Sun and the solar events of the equinoxes and solstices. In the northern hemisphere, spring ends and summer begins at the June solstice, which occurs between June 20 and June 22 each year. Summer ends and autumn begins on the September equinox, which occurs between September 21 and 24 each year. Summer in the Southern Hemisphere runs from the December solstice (December 20 to 23) to the March equinox (March 19 to 21).
The summer start and end dates on this page are based on astronomical summer dates in the Northern Hemisphere and Coordinated Universal Time (UTC), which for practical purposes corresponds to Greenwich Mean Time (GMT – Time Zone). Great Britain). Summer begins and ends in the Northern Hemisphere, and the date and local time vary from place to place depending on the year and time zone of the place. It may fall the next day for places ahead of UTC (further east) and the day before for places behind UTC (further west).

Climatologists, on the other hand, define seasons based on weather conditions and the annual temperature cycle. It is important for them to compare the same period in different years. The length of the astronomical seasons varies from 89 to 93 days, while the length of the meteorological seasons is less variable, with winter set at 90 days in a leap year (91 days in a leap year), and spring at 92 days. 91 days in summer and autumn. While the exact definition of the timing and length of the season may vary from region to region based on local conditions, in most regions of the Northern Hemisphere the climatic summer is generally defined as the three months of June, July and August, with the season beginning in June . Ends 31 August.
Longest Day (summer Solstice)
There is no “official law” that defines summer, and different countries follow different traditions. Most of North America and Europe use astronomical summer, while Australia and New Zealand use meteorological summer (but because these countries are in the southern hemisphere, the seasons are reversed, with summer lasting from December to February). In other cultures, e.g. In the traditional Chinese calendar and Celtic traditions, the June solstice is considered roughly the middle of summer. In the United States, summer often begins on Memorial Day (the last Monday in May) and ends on Labor Day (the first Monday in September), in terms of cultural events.
