What happens when Earth has 2 full moons in one calendar month?

Nothing extraordinary happens. Though not very frequently, there will be two full moons in one month due the the moon's cycle and our calender system. By the way, the second full moon of that month is called a "blue moon" (that's where the phrase "once in a blue moon" comes from). It is interesting that there are other ways to define Blue Moon. See link for more information.

∙ 14y agoIt is called a blue moon. It comes from having more days ( about 11) in the year than the 12 lunar cycles.
Every few years there are enough days to accumulated to have an extra full moon.
Since this is an uncommon event, we have the expression "once in a blue moon."

∙ 15y agoNothing really happens. The second full moon in a month is sometimes called a "blue moon". The moon orbits the earth approximately every 28 days and since some months have more than 28 days it is possible and happens from time to time.

∙ 11y agothere isn't always 2 full moons in one month but this can happen when it does its called a blue moon.But a blue moon is also a figure of speech.For Example(I do homework once in a blue moon.
A blue moon can happen because a full cycle of moon phases repeats in 29.53 days,
and 11 of the 12 months are longer than that. That means that whatever phase the
moon is in when the month begins, that phase will repeat before the month ends. If
it happens to be a Full one, then there'll be another Full one before the month ends.

The interval between full moons is 29.53 days. So February can never have two full
moons, because the whole month never has 29-1/2 days in it, even in a leap year.
Concerning the other months:
In order for April, June, Sept, or November to have two full moons, the first one
must be in the first 12 hours of the 1st of the month, so the second one can fit in
during the last 12 hours of the 30th.
In order for January, March, May, July, August, October, or December to have two
full moons, the first one must be either on the 1st of the month, or else in the first
12 hours of the 2nd, so that the second one can fit in between the middle of the 30th
and the end of the 31st.
Here's another way to look at it:
One whole year is 365.23 days long. The space between two full moons is 29.53 days.
So there's time for (365.23/29.53) = 12.37 periods between full moons, or an absolute
max of 13.37 full moons in one year. With only 12 months in the year, you can't squeeze
two full moons into very many of them.
And that's why it doesn't happen too often.

∙ 14y agoIf there is two full-moons, the first full-moon is called a full-moon and the second one is called a blue moon.
Wiki User
∙ 13y agoAbsolutely. You're entitled to have as many of them as you want, at intervals of 29.53 days.

And the axis might shift.
The gravitational pull on Earth might change.
It would really throw us off balance.

∙ 14y agoNothing special; that happens every other year, on average. Some people call this a "blue Moon".
A point of trivia; February is the only month that can't have a "blue" Moon.

Could there be two new moons in a month?
yes it happens every 27 days not 30. The chances of 2 New Moons in a month are just the same as 2 full moons, but because New moons are generally invisible, most people tend not to notice the occasions when a month has 2 of them!

When does a blue moon happen?

How many full moons are there in a month?
How many full moons per month? Usually, one, but it is possible to have two, as there are 13 lunar months and 12 calendar months in a year. When do full moons occur? The moon revolves around the earth roughly once each month. (Moonth). When the moon is on the opposite side of the earth from the sun, it catches the full sunlight, making it look big and round. When the sun and moon are on the same side of the earth, all we see in the lunar night side. This is called the "new" moon. Half moons result when the earth is at roughly right angles to the moon and sun.
Why does a full moon occur twice in one month?
Actually, the natural cycle of the moon phases was happening first, before humans came along and invented the calendar. So the month is based on the moon. However, any month other than February is longer than the lunar cycle, so occasionally there are two full moons in a month--one on the first or second, and one at the end of the month.

How many days are there in a mercury month?
It doesn't make sense to talk about a "Mercury month". Here on Earth, the month is defined by the Moon's revolution around Earth. At least, that's what the term "month" meant originally. There is no equivalent on Mercury, which has no moons. Of course, you could use any arbitrary time period and call it a "month", but there is no generally agreed-upon "month" for other planets, whether they have moons or not.
Where is the moon found?
The moon can be found in space. Moons will orbit around planets that have moons. Earth has one moon that gives four different phases each month.
How moons are in earth?
