"Sunset Season" refers to the time of year when the days begin to shorten, leading to earlier sunsets. This seasonal change typically occurs in the fall, as the Earth tilts away from the sun. The vibrant colors of the sky during this time, including shades of orange, pink, and purple, are caused by the scattering of sunlight in the atmosphere. During Sunset Season, many people enjoy outdoor activities like hiking or picnicking to witness the beautiful evening skies. This period is also associated with various cultural events and festivals that celebrate the changing seasons, making it a time of reflection and appreciation for nature's beauty.
