Starts around September 22 or 23 . Like the spring equinox, the sun crosses the equator again, signaling the transition into cooler months.
Whether you follow the stars or the thermometer, the changing seasons remain one of nature’s most predictable and beautiful rhythms.
Most people are familiar with the astronomical seasons. These are defined by the Earth's position relative to the sun. Because the Earth is tilted on its axis at roughly 23.5 degrees, different parts of the planet receive varying amounts of sunlight throughout the year. when do the four seasons start and end
Understanding the timing of the four seasons requires looking at both the tilt of the Earth and the patterns of our atmosphere. Here is everything you need to know about when the seasons start and end. 1. The Astronomical Approach (Solstices and Equinoxes)
While the calendar on your wall gives you a specific date for the start of spring or fall, the "true" beginning of a season depends entirely on who you ask—an astronomer or a meteorologist. Starts around September 22 or 23
If you’ve ever noticed that it feels like summer in early June, even though the "official" start isn't until the 21st, you’re thinking like a meteorologist.
It is important to remember that seasons are inverted between the Northern and Southern Hemispheres. When the Northern Hemisphere is experiencing the Winter Solstice in December, the Southern Hemisphere (countries like Australia and Brazil) is celebrating the Summer Solstice. Most people are familiar with the astronomical seasons
You might notice that the astronomical start dates move slightly from year to year (e.g., Spring starting on March 20th one year and the 21st the next). This happens because a solar year is actually long, not exactly 365. Our Gregorian calendar accounts for this with Leap Years, which resets the alignment and causes those minor shifts in the equinox and solstice dates. 4. The Hemisphere Flip
Starts around March 20 or 21 . On this day, the sun passes directly over the equator, making day and night nearly equal in length.
