  Month - LoveToKnow 1911
At common law, "month" generally means a lunar month, although in mercantile matters it has been generally understood to mean a calendar month, but there is no general exception giving it that meaning in commercial documents.
In the rules of the supreme court and in the county court rules month means a calendar month.
In mercantile contracts in computing the period of a month the day from which the time is to begin to run is excluded, but in sentences of imprisonment the day on which the sentence begins is included, so that the numerically corresponding day in the month in which the sentence expires would be excluded.

The month is a unit of time, used with calendars, which is approximately as long as some natural period related to the motion of the Moon.
The apparent diameter of the full moon varies with the full moon cycle which is the beat period of the synodic and anomalistic month, and also the period after which the apsides point to the Sun again.
The "draconic/draconitic" month refers to the mythological dragon that lives in the nodes and regularly eats the Sun or Moon during an eclipse.

 Fumocy
The variation in apparent size of the Moon is due to the fact that the orbit of the Moon is distinctly elliptic, and as a consequence at one time it is nearer to the Earth (perigee) than half an orbit later (apogee).
The period of the Moon's phases, that is the motion of the Moon with respect to the Sun, is called synodic month.
There are 13.944335 synodic months in a fumocy, the 251-month cycle approximates the fumocy to 13.944444 synodic months and the 767-month cycle approximates the fumocy to 13.9454545 synodic months.

The actual period of the Moon's orbit as measured in a fixed frame of reference is known as a sidereal month, because it is the time it takes the Moon to return to the same position on the celestial sphere among the fixed stars (Latin: sidus): about 27 1/3 days on average.
223 synodic months is approximately equal to 239 anomalistic months and to 242 draconic months.
This is useful for designing purely lunar calendars, where months of 29 and 30 days occur in some pattern that repeats after some number of months.

The actual period of the Moon's orbit as measured in a fixed frame of reference is known as a sidereal month (\\sī-dir'-ē-ǝl, sǝ- \\), because it is the time it takes the Moon to return to the same position on the celestial sphere among the fixed stars (Latin: sidus): 27.
Hence the time it takes the Moon to return to the same node is again shorter than a sidereal month: this is called the draconic (\\drā-cŏn'-ĭk\\) month, which has an average length of about 27 1/5 days.

 Eclipses
Anomalistic month: The time interval between two successive perigee (closest) or apogee (farthest) passages of the moon.
The Anomalistic month is longer than the sidereal month: Since the line of apsides makes one complete revolution in a period of 8.85 years, the perigee and apogee positions are continuously changing their direction in the sky.
The residual in the anomalistic period when compared to the synodic period (0.217 day) will cause a gradual shift in the distance of the moon from the earth during a saros cycle.

 Lunar month - Wikipedia, the free encyclopedia
But all lunar months approximate the mean length of the synodic month of approximately 29.53059 days (29 days, 12 hours, 44 minutes and 3 seconds).
An anomalistic month is the Moon's orbital period measured from perigee to perigee - the point in the Moon's orbit when it is closest to Earth.
The draconic month or nodal month is the period in which the Moon returns to the same node of its orbit; the nodes are the two points where the Moon's orbit crosses the Earth's orbit.

 "The Trouble with Months" -- skw9606
That there are two full moons this month indicates the difficulty of trying to fit the lunar revolution period into calendars as a fixed measure of time.
It is the synodic month that is easiest to identify, both for us now and for ancient lunar observers when calendars were first being developed.
The difficulty with the synodic month is that it varies from 29.26 to 29.80 days with an average length of 29.530588 days.

The tropical month is the amount of time for the Moon to complete one orbit around the Earth in relation to the equinox and solstice points (which shift relative to the stars because of precession).
The synodic month is the amount of time for the Moon to complete one orbit around the Earth, measured from new moon to new moon —; the common "lunar month" used for calendar purposes.
30 is the closest integer to the length of the synodic month.

The average duration of the anomalistic month is approximately 27.554549 days; while the average duration of the synodic month is approximately 29.530588 days.
After 1 fumocy, the accumulated difference between the number of completed anomalistic months and the number of completed synodic months is exactly one.
Now I am left to wonder if anomalistic is synchronistic or synonym-istic with animalistic and that, perhaps that might explain werewolves, menstrual cycles and the periodic madness of imbibing the demon rum.

 anomalistic year - HighBeam Encyclopedia
anomalistic year, time required for the earth to go from the perihelion point once around the sun and back to the perihelion point.
It is 365 days, 6 hr, 13 min, 53.0 sec of mean solar time (see solar time).
The anomalistic year is longer than the sidereal year and the tropical year because of the eastward motion of the line of apsides (see apsis), which is caused by the slow rotation of the earth's orbit as a whole.

The word "month" may be used to mean many different things, with the calendar month of over 30 days being the only one not related to the moon.
Because of this wobble of the moon's orbit, there is another month called the nodical month which is 27.21 days, being the time between crossing the earth's equator going in the same direction.
The returns of the moon to the closest point to the earth is another month, called the anomalistic month which is 27.55 days long.

 The Metonic Cycle and the Saros   (Site not responding. Last check: 2007-10-13)
The metonic cycle was used to determine how intercalary months could be inserted into a lunar calendar so that the calendar year and the tropical (seasonal) year were kept in step.
He mistakenly connected the naming of a cycle of 223 synodic months by the tenth century Greek lexicographer Suidas with the eclipse cycle of the same period.
It also happens that the Saros is also nearly equal to 239 anomalistic months (the time between successive closest approaches of the Moon to the Earth) and so the length of the eclipses in each cycle will be approximately the same.

 Chapter 1: PREDICTABLE PERIODIC EVENTS-PART I
The duration of an eclipse-season results from the fact that the sun's eclipse zone is 37 degrees or within 18.5 degrees of the node (point on orbital plane where moon crosses).
However, because the moon's eclipse zone is 12.25 degree from the node (or 24.5 degrees wide) and it takes 30.616 degrees for the moon to travel to its nodal position a synodic month later, the moon cannot have more than one partial or total eclipse during a three eclipse-season.
Interval required for the Sun to move from the moon's ascending node to ascending node or descending node to descending node.

A month is that from one date to the next months date with the same number.
The month is a unit of time, used with calendars, which is approximately as long as some natural period related to the motion of the Moon (moon gives month in the same way that wide gives width and broad gives breadth).
This longer period is called the anomalistic month, and has an average length of 27.554 551 days (27d 13h 18min 33.2sec), or about 27
