Here are some apparent facts about Full Moon and February.
Don McDonald, Wellington, NZ. (E.g. Richard Hall, Carter Observatory,
Radio New Zealand, 12-JAN-2004.)

What is 'blue moon?'
Answer- A month with 2 Full Moon's in it.

A lunar month is 29.53 days (average.) Therefore, can you
have 2x Full moons in the month February, 28 days?

Yes. (Richard Hall, Carter Observatory WGTN, agreed-
at a squeeze you can!)

Nevertheless (Don) it needs to be a leap year, Feb. 29 days, and
around the World, using Time Zones and International date line.

[ Mensa International Journal, Donna Jardis
[ Wellington Astronomical Soc., Brenda,


Kate Nacard's column, 'ABC Words', (Mensa IJ Extra!, March 2003,)
writes: The Maine Farmer's Almanac (1932) gave another definition of
'blue moon' as a season that held four new moons rather than three... .

I calculated an example;-
New and Full Moons for the year 2052

(All times are in GMT)

NEW

Tuesday 2 January 3:07
Wednesday 31 January** 18:32
(= 1 Feb. New Zealand, GMT+13hrs.)

Friday 1 March ** 7:38
(= 29 Feb. Pacific Ocean, GMT-8hrs.)

Saturday 30 March 18:29

Evidently, there will be NO NEW Moon at Greenwich Prime Meridian
during February 2052, Leap Year. However, there should be 4 New
moons between January and March.

My special point is this- Therefore
**2x New Moons** in February (sic).
E.g. 1 in New Zealand 01 FEB 2052 (GMT +13 hrs) and
another, second in Pacific Ocean, 29 FEB 2052 (GMT -minus 8 hrs.)


2x New Moons in the shortest month of year!
Using dateline, timezones, and Leap year.

I propose, Is it possible for the World to have 2 full moons in a
month with 29 days; Leap Year? (What is the nearest miss?)

Consider the effects: Crossing the International Date Line gives 30 days
for February, compared to synodic month 29.531 days. On the other hand,
perihelion, Earth nearest to Sun, increases the interval between full
moons (Kepler's Second Law of planetary motions; Earth's orbital
speed increases.) And the years and months I expect would have
variations.

The first full moon would be in New Zealand (new zealand daylight time =
Greenwich Mean Time + 13 hours) and the second somewhere in the
South Pacific Ocean (GMT -minus 10 hrs.)


Extremely rare.
IF... there is a Valentine's Day Full Moon, 14 February,
at Greenwich (GMT) and Leap year, THEN
there is also a chance of 1 FEB (year 2052) New moon, New Zealand
(NZ Daylight Time = GMT +13 hours)
and 29 Feb 2052 New Moon, Pacific Ocean. (Table above.)

How many days has the lunar month? Answer.
The 'synodic month' (between 2 successive new moons) averages 29.531 days.
February has average 28.2425 days, Gregorian calendar. Therefore, about
once every (23 years?), February has no full moon.
Example Year 1999.


[Once every 6 years (terrible guess??) February has only 3 phases
of the Moon somewhere on Earth. New, First Quarter, Full, Last
Quarter.]

....
However, I remain hopeful that, if February has no Full Moon, THEN BOTH
January and March of the same year are likely to experience 2 Full Moons
each! The Computer program confirms this for Year 1999.
