Synodic Month
The mean interval between conjunctions of the and , corresponding to the cycle of lunar phases. However, any particular phase cycle may vary from the mean by up to seven hours.
synodic month -- the time from one full Moon to the next (about 29.5 days).
third contact -- the end of the total phase of a solar eclipse marked by the trailing edge of the Moon first revealing the Sun.
Synodic month: the interval between two successive New Moons.
Draconic month: the interval between two successive passages of the Moon through the same node of its orbit.
synodic month Time required for the Moon to complete a full cycle of phases.

synodic month
The length of time for the Moon to go through one complete lunar cycle. It is the orbital period of the Moon with respect to the Sun.

Synodic Month
The period of time (29.53 days) between two successive identical phases of the Moon, e.g., new Moon to new Moon or full Moon to full Moon (see Lunation).

SYNODIC MONTH
A synodic month (also called a lunar month) is the time between successive new or full moons. It lasts 29 days, 12 hours, and 44 minutes.
(Synodic Month) - 29.5 days - One revolution with respect to the Sun. This is the time frame that determines lunar phases. Used as the basis for the first Roman Calendar.

The traditional value (from Babylonian System B) for the mean synodic month is 29 days;31,50,8,20 (sexagesimal) = 29.5305941... d.
5 days to return to the same point on the celestial sphere as referenced to the Sun because of the motion of the Earth around the Sun; this is called a synodic month (Lunar phases as observed from the Earth are correlated with the synodic month).
The origin of the Saros cycle comes from the recognition that 223 synodic months is approximately equal to 242 draconic months, which is approximately equal to 239 anomalistic months (this approximation is good to within about 2 hours).
223 synodic months (6585.321 days) almost equal 242 draconic months (6585.357 days), a period of 18 years 10 and 1/3 (or 11 and 1/3) days -- depending on the number of intervening leap years.
There are clumpings of six lunar synodic months (178 days) followed by one set of five (148 days). Each bunch of five moons is followed by a picture.
If the Synodic months (lunar) are used to count a year, 12 synodic months equal 354.36706 days. This is almost 11 days shorter than the tropical year. And if used it throws the seasons out of sync.
The interval contains 223 synodic months (6585.32 days) and 19 ecliptic years (6585.78 days). (It also contains 242 nodical months.) The difference of a fraction of a day causes each eclipse to fall about 120° west of the previous eclipse. [H76] ...

5 days, the period known as the synodic month. Star watchers in ancient times attempted to arrange the days and either the months or the years into a consistent time system, or calendar.
531 days, the synodic month. These periods are slowly changing with time owing to tidal interactions. Tidal friction slows the Earth's rotation, but the angular momentum of the Earth-Moon system remains constant.
The Moon goes through a cycle of phases that repeats every 29.531 days (a synodic month). We see these phase changes occur with the Moon rising between 20-70 minutes later each day.

The apparent motion of the Moon is similar. The time between successive full Moons is the synodic month, it is 29.5 days long. Note that the Chinese calendar is based on both the motions of the Moon and the Sun, not just the Moon.
LUNAR MONTH
A lunar month (also called a synodic month) is the time between successive new or full moons. It lasts 29 days, 12 hours, and 44 minutes.
The mean interval is 29 days 12 hours 44 minutes 3 seconds (the synodic month) but, because of the perturbing action of the sun, the difference between the shortest and longest lunations in the 20th century is about 13 hours.
Lunation. One complete cycle of phases by the Moon, 29.53 days. A lunation is also known as a Synodic month.

PHASE2 - Amount of illumination by sunlight of a planetary body as observed from Earth. The Moon goes through a cycle of phases that repeats every 29.531 days (synodic month).
Measured with respect to an alignment of astronomical bodies other than or in addition to the sun or the stars (usually the moon or a planet). For example, a synodic month depends on the positions of the sun, earth, and moon.
synodic period - (n.) ...
Astronomers now recognize different kinds of months, such as the synodic month of 29 days, 12 hr, 44 min, the period of the lunar phases, and the sidereal month of 27 days, 7 hr, 43 min, the period of lunar revolution around the earth.
Lunar Month
The average time between successive new or full moons. A lunar month is equal to 29 days 12 hours 44 minutes. Also called a synodic month.
However, during one sidereal month, the Earth has revolved part way around the Sun, making the average time between one new moon and the next longer than the sidereal month: it is approximately 29.5 days. This is known as the synodic month, ...
