Seasons Fixed | When Are The

Occurs around June 20th–21st. On this day, the Sun reaches its highest declination (angular distance from the celestial equator), appearing directly overhead at the Tropic of Cancer (23.5° N latitude). The North Pole is tilted maximally toward the Sun. This is the longest day of the year in the Northern Hemisphere and the shortest in the Southern Hemisphere. It is the astronomical beginning of summer in the north and winter in the south.

The four seasonal "starting points" are not arbitrary dates. They are astronomical events, defined by the Sun’s apparent position relative to the celestial equator (an imaginary projection of Earth’s equator into space). These events are the two and the two equinoxes .

The moments when one of Earth's poles is tilted at its maximum toward or away from the sun. Summer Solstice: The longest day of the year. Winter Solstice: The shortest day of the year.

In conclusion, the seasons are a natural phenomenon caused by the Earth's axial tilt and orbit around the Sun. Understanding the seasons and their characteristics can help us appreciate the dynamic nature of our planet and prepare for the changing weather patterns throughout the year.
