One rotation by the Earth round its axis to bring the 'mean Sun' back to the meridian defines one day.
The mean Sun is a Sun which comes to the meridian regularly once a day. In practice the real Sun can be fast or slow by up to 10 minutes, so the mean Sun is a fictitious sun for which those daily variations are averaged out over a year.
