Thirteen full moons occur over a period of approximately 12 months. Since a lunar cycle, or the time between one full moon and the next, is about 29.5 days, 13 full moons would take around 354 days to complete. This is about 11 days shorter than a typical calendar year, which is why some years can have 13 full moons, often referred to as a "blue moon" when the second full moon occurs in a single month.
There were 13 full moons in 1982. The number of full moons varies each year. In 1983 there were 12 full moons and in 1984 there were also 12 full moons.
The exact number of full moons fluctuates by year, as the lunar calendar is only roughly twenty nine days long. In 2013, there will be twelve full moons.
There are typically 12 full moons in a year, with one occurring each month. However, some years may have 13 full moons due to the occurrence of a blue moon, which is the second full moon in a calendar month. On average, about every 2.5 to 3 years will have this extra full moon.
Uranus is the planet with rings and a total of 13 moons. It has 13 known rings and 27 known moons, with 13 of those moons being inner regular moons.
There are more than 250 planetary satellites currently documented in thesolar system, including exactly one in orbit around the earth.Perhaps when you say "13 moons", you're asking about 13 full moons in onecalendar year.As pathetic as it must appear on a Q-&-A site to be responsible for definingone's own questions before answering them, we'll rise to the bait nonetheless.If the first Full Moon of the calendar year occurs by January 10th, then there'senough time remaining in that year for 12 more.Since there's no mathematical relationship between the phases of the moon andthe modern calendar, we can assume that over the long term of many years, thefirst Full Moon of the year is equally likely to occur on any one of the first 30 daysof January. So the chance of it arriving in the first 10 days must be 10 out of 30.Consequently and accordingly, we'll say that on the average, one year out of threehas 13 Full Moons.

13 Full Moons in a Year

The question is a little vague; I'm going to assume you mean full moons. The synodic period (the time between two full moons) averages 29.53 days, which works out to about 12.4 of them per year. In any given calendar year there are either 12 or 13 full moons. 2014 is a "12 full moons" year; 2015 will have 13.
