A year is the time it takes for the Earth to complete one orbit around the Sun. This period is approximately 365.25 days long. The year is divided into 12 months and is an important unit of time in our calendar system.
The actual length of a year is approximately 365.25 days, which is why we have a leap year every 4 years to account for the extra 0.25 day. This is why some years have 366 days instead of the usual 365.
The Earth's orbit around the Sun causes the changing of seasons. The tilt of the Earth's axis relative to its orbit around the Sun is the primary reason for the seasons. As the Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight, leading to the four seasons: spring, summer, autumn, and winter.
There are various activities associated with different times of the year. For example, winter is often associated with snow and cold weather, while summer is known for its warmth and outdoor activities.
