How often does Local Apparent Time change?

Local Apparent Time changes seasonally due to the Earth's axial tilt and its elliptical orbit around the sun. The tilt of the Earth's axis impacts the angle at which sunlight reaches different parts of the Earth throughout the year, leading to variations in the length of daylight and the position of the sun in the sky at different times of the year. As a result, Local Apparent Time will differ based on the season and is not uniform throughout the year.

In astronomical terms, Local Apparent Time is closely tied to the concept of solar time, which reflects the position of the sun. Since the Earth's orbit is not a perfect circle and its axis is tilted, the solar day can vary in length, leading to the need for adjustments in local timekeeping. This seasonal variation is contrasted with other options, where consistent hour changes or uniformity throughout the year do not capture the influence of Earth's axial tilt and orbital characteristics on solar position and timekeeping.
