A blue moon according to the current definition is the second full moon that occurs within the same calendar?

Question

month. Is it possible for a blue moon to occur in our present calendar system?why? Are there any months of the year in our revised gregorian calender system in which it is impossible to have two full moons? why?

Answer 1

yes it is. A few years ago we had 2 blue moons in one month. I remember thinking, that will never happen again in my life time

Answer 2

It's impossible for February to have two full moons, even in a leap year, as the time between full moons is a little more than 29 days. However, it is possible for February to have no full moon at all, in which case there will be two months with two full moons. The two months are usually (but not necessarily) January and March. This last happened in 1999. Here a link with some fun stuff about this:

Answer 3

A lunar cycle is 28 days long. So, you can have a Blue Moon in any month that has more than 28 days. February would be the only month in which a Blue Moon cannot occur, unless it is a leap year - in which case, I believe it is called a Periwinkle Moon.

Answer 4

of course, the moon is on about a 28 day cycle, the real trip is the ultrarare Feb. blue moon,

in 1999, there was a semi blue moon, with one occuring on feb 1st, and in certain areas the second came on the 28th, though in some places the second was Mar 1, some some places had a blue moon in Feb, some in Mar, and so fourth, and it should be likely that at some point, it would occur in Feb on a leap year, though I don't know when that would be.

Answer 5

Yeah. it happened when the redsox won the world series.

Answer 6

Of course it is!
