Seasons are determined by the Earth's tilt on its axis and its revolution around the Sun. As the Earth orbits the Sun, different parts of the planet receive more or less direct sunlight at different times of the year. This difference in sunlight causes the seasons to change.
In the Northern Hemisphere, winter begins on December 21 or 22 and ends on March 20 or 21. Spring begins on March 21 or 22 and ends on June 20 or 21. Summer begins on June 21 or 22 and ends on September 22 or 23. Autumn (or fall) begins on September 22 or 23 and ends on December 20 or 21.
The dates of the seasons can vary slightly from year to year, but they are generally consistent. This is because the Earth's orbit around the Sun is not perfectly circular, and the Earth's axis is not perfectly perpendicular to its orbit. These slight variations in the Earth's orbit and axis cause the dates of the seasons to change slightly from year to year.
Which Months Are Which Seasons
The Earth's tilt and orbit cause seasons.

- Spring: March - May
- Summer: June - August
- Autumn: September - November
- Southern Hemisphere:
- Summer: December - February
- Autumn: March - May
- Winter: June - August
- Spring: September - November
Dates vary slightly each year.
Northern Hemisphere:
In the Northern Hemisphere, winter begins on December 21 or 22 and ends on March 20 or 21. This is the coldest time of the year, with average temperatures below freezing in many areas. Days are shorter and nights are longer during winter. Snow and ice are common in many parts of the Northern Hemisphere during this season.
Spring begins on March 21 or 22 and ends on June 20 or 21. This is a time of transition, as the weather begins to warm up and the days start to get longer. Flowers bloom and trees begin to bud during spring. This is also a time of increased rainfall in many areas.
Summer begins on June 21 or 22 and ends on September 22 or 23. This is the warmest time of the year, with average temperatures above 70 degrees Fahrenheit in many areas. Days are longer and nights are shorter during summer. Many people enjoy spending time outdoors during this season, swimming, hiking, and camping.
Autumn (or fall) begins on September 22 or 23 and ends on December 20 or 21. This is a time of transition, as the weather begins to cool down and the days start to get shorter. Leaves change color and fall from the trees during autumn. This is also a time of harvest, as farmers gather their crops.
The dates of the seasons can vary slightly from year to year, but they are generally consistent.
