= Synodic day
{wiki=Synodic_day}
A synodic day refers to the time it takes for a celestial body, such as a planet, to rotate once on its axis relative to the position of the Sun as seen from that body. In simpler terms, it is the duration between two successive sunrises or sunsets observed on the surface of the planet. For instance, the synodic day on Earth is approximately 24 hours, which is the time it takes for the Earth to complete one full rotation relative to the Sun.
