Wikipedia
Lunar day
A lunar day is the period of time for Earth's Moon to complete one rotation on its axis with respect to the Sun. Due to tidal locking, this equals the time that the Moon takes to complete one orbit around Earth (Earth rise to Earth set) plus about 2.2 more Earth days to return to the same Moon phase (due to the Moon's orbit around the Sun). The lunar day is roughly 29 1/2 Earth days, the length of a lunar month, and the time of which includes a full day-night cycle.

Lunar day
A lunar day is the period of time it takes for the Earth's Moon to complete one full rotation on its axis with respect to the Sun. Equivalently, it is the time it takes the Moon to make one complete orbit around the Earth and come back to the same phase. It is marked from a new moon to the next new moon. With respect to the stars, the Moon takes 27 Earth days, 7 hours and 43.2 minutes to complete its orbit; but since the Earth-Moon system advances around the Sun in the meantime, the Moon must travel further to get back to the same phase. On average, this synodic period lasts 29 days, 12 hours, 44 minutes and 3 seconds. This is an average figure, since the speed of the Earth-Moon system around the Sun varies slightly over a year, due to the eccentricity of the orbit. The Moon's own orbit also undergoes a number of periodic variations about its mean value, due to the gravitational perturbations of the Sun.
