What Are Earth's Standard Seasons
Earth traditionally has four seasons: spring, summer, autumn, and winter. These are caused by the tilt of Earth's axis as it orbits the Sun.
Are There Two New Seasons
Some informal discussions suggest Earth has two new seasons, but major scientific sources do not recognize additional official seasons. The standard four-season model remains the widely used framework for climate and weather tracking.
How Seasons Are Defined and Measured
Meteorologists and climatologists define seasons using temperature and weather patterns. Astronomical seasons are based on Earth's position relative to the Sun. You can read more about seasonal definitions from authoritative sources such as National Weather Service.
