The Earth takes approximately 365.25 days to complete one orbit around the Sun, which is why we have leap years every four years to account for the extra quarter day. However, the number of days in a year does not directly correlate to the number of times each side of the Earth sees the Sun.
As the Earth orbits the Sun, the tilt of its axis causes the occurrence of seasons and variations in daylight hours in different parts of the world. The axial tilt is responsible for the phenomenon of daylight hours changing throughout the year.
On any given day, approximately half of the Earth is in daylight while the other half is in darkness. The specific locations that experience daylight or darkness change throughout the year as the Earth progresses in its orbit. This means that each side of the Earth does not have exactly half of the year in daylight and the other half in darkness.
The concept of "seeing the Sun" in this context is also affected by factors such as time zones and the rotation of the Earth on its axis. As the Earth rotates, different regions experience sunrise and sunset, ensuring that over the course of a year, both sides of the Earth will have experienced daylight and nighttime.
To summarize, the Earth's year is approximately 365.25 days long, but the distribution of daylight and darkness across the planet varies throughout the year due to the Earth's tilt and its rotation. Each side of the Earth does not have precisely 183 days of daylight or darkness, and the concept of "seeing the Sun" is influenced by various factors.
