The dates of the four seasons vary slightly from year to year due to the Earth's elliptical orbit around the Sun. However, the following dates are generally accepted as the start and end dates of each season:
| Season | Start Date | End Date | Why these months? | | :--- | :--- | :--- | :--- | | | March 1 | May 31 | Captures the full warming trend from early March (still cold) to late May (warm). | | Summer | June 1 | August 31 | Includes the hottest months of the year for most of the Northern Hemisphere. | | Autumn | September 1 | November 30 | Captures the cooling from late summer heat to pre-winter chill. | | Winter | December 1 | February 28/29 | Covers the coldest sustained temperatures. |
The meteorological system was created by scientists and climatologists for statistical tracking. Instead of relying on the varying position of the stars, meteorologists group the year into four neat, three-month periods based on the annual temperature cycle and the Gregorian calendar.
Just like the spring counterpart, the sun crosses the celestial equator moving southward. Day and night balance out once again as global temperatures begin to drop. Winter (Hibernal Solstice) Northern Hemisphere Start: December 20–23 Northern Hemisphere End: March 19–21 Southern Hemisphere Start: June 20–22 Southern Hemisphere End: September 21–23 when do the four seasons start and end
Meteorologists and climatologists use fixed calendar dates for simpler record-keeping and forecasting. These seasons align more closely with the annual temperature cycle. The dates are fixed and do not vary by year.
Typical dates (Northern Hemisphere)
Ultimately, whether you follow the astronomical calendar tracked by the stars or the meteorological calendar used by your local weather app, the shifting of the seasons remains a beautiful reminder of our planet's constant journey around the sun. The dates of the four seasons vary slightly
Near the equator, the amount of sunlight changes very little throughout the year, and temperatures remain consistently warm. Instead of four seasons, these regions usually have just two: the Wet (Monsoon) Season and the Dry Season .
I should structure the article to first address the core confusion head-on. Introduce the two systems clearly. Then explain each one in detail with tables and reasoning. Include cultural/natural markers as a third perspective for completeness. Need to address Northern vs. Southern Hemisphere specifically, as that's a major point of error. A comparison table and frequently asked questions would add value and length. End with a clear summary and a practical note about local climate variability.
It is vital to remember that the seasons are reversed below the equator. If you live in Australia, South Africa, or Argentina, the astronomical calendar flips: | | Summer | June 1 | August

The four seasons - spring, summer, autumn (or fall), and winter - are a fundamental part of our planet's annual cycle. Each season brings its own unique characteristics, weather patterns, and activities, and understanding when they start and end can help us make the most of the year. In this article, we'll explore the exact dates of the four seasons and what you can expect during each one.
Now, let’s explore why these two systems exist, why the dates fluctuate, and what they mean for you.
