^new^ - When Do The Four Seasons Start And End

Astronomical seasons are defined by the physical position of the Earth relative to the Sun. Because the Earth is tilted on its axis by roughly 23.5 degrees, different parts of the planet receive varying amounts of sunlight throughout its 365-day orbit. This system relies on four precise cosmic events:

In short, if you follow the , the seasons begin around the 20th–22nd of the month. If you follow weather patterns and the calendar , they begin on the 1st. Both systems provide a useful way to organize our lives around the natural rhythm of the planet.

The most important takeaway is to understand the difference so you can avoid confusion. When a weather report says, "Temperatures will be above average for this winter," they are using the meteorological calendar (Dec-Feb). When a calendar says, "First Day of Spring," it is likely using the astronomical calendar (March equinox). when do the four seasons start and end

Because of seasonal lag and specific heat . The ground and oceans take time to warm up. Even though the sun is higher in the sky, the Earth is still releasing stored heat from winter. This is why May is typically warmer than March, even though the sun intensity is similar.

Therefore, if you live south of the equator, the dates flip: is Summer. March to May is Autumn. June to August is Winter. September to November is Spring. Why Don't the Dates Match the Weather? Astronomical seasons are defined by the physical position

Most regions near the equator do not have the traditional four seasons. Instead, they have a (monsoon) and a dry season . The tilt of the Earth has less effect on temperature there; rainfall patterns determine the "seasons."

works best with consistent, full-month blocks (Meteorological). If you follow weather patterns and the calendar

Spring (March), Summer (June), Fall (Sept), Winter (Dec).

August 31, 2026 (Meteorological) / September 21, 2026 (Astronomical)

Derived from the Latin word for "equal night," these are the two days of the year when the sun sits directly above the Earth's equator, resulting in roughly 12 hours of daylight and 12 hours of darkness everywhere on Earth.
