The synodic period of the Moon is the time it takes for the Moon to return to the same phase (e.g. from full moon to full moon) and is approximately 29.5 days long. The sidereal period refers to the time it takes for the Moon to complete one orbit around the Earth relative to the stars (about 27.3 days), while the Saros cycle is a period of approximately 18 years and 11 days after which eclipses of the Sun and Moon repeat. The umbral period refers to the time it takes for the Moon to move across the Earth's umbral shadow during an eclipse, and eclipse season refers to the period of time when the Sun is in the same relative position to the Moon's nodes, increasing the likelihood of eclipses.
