epidavros - You're right. This was more of a 'Trivia' question, but I wanted to pose it to those interested in astronomy. The February of 1865 is the only month in recorded history not to have a full moon. Have fun, guys. (^_^)

I don't know if it has ever happened, but...the phases of the moon repeat every 29.5 days (that's the synodic period of the moon), that is, the time it takes for the moon to return to the same relative position with respect to the sun. This is longer than the sidereal period, which is the time it takes for the moon to complete one full revolution around the earth, because the earth moves about 27 degrees around the sun in 27.3 days. So, even though the moon is in the same position with respect to the stars (sidereal period) the sun has apparently moved, and it takes a bit more than two more days for the moon to catch up to the sun (and complete it's synodic period).

Therefore, if a full moon were to occur on January 31(possibly the 30th, if late enough and February has only 28 days that year), the next one would not occur until March, and February would have none.

Yes.

They are not as common as months with a second full moon - a so called blue moon. And the month is, of course, always February.

The last one was in 1991 is Asia and the Pacific (differences in time zones mean that the new moon occured late on Feb 28th elsewhere on Earth rather than on 1st March). The next will be in 2018.

The relevant issue is the definition of a month. Most calendars define it in terms of moon cycles, but abberations caused by changes or adjustments to calendars have caused the superficial appearance of such events. One example is the change from the julian to the gregorian calendar, which occured in different years in different countries.

No. By the very nature of the moon's orbit around the earth, it goes through all its phases each month.

Not possible, full moon occurs every 28 days.
