There are two types of months, or calendars, that astronomers use: the lunar and the solar. The solar months are the more familiar calendar and one example of a solar month is January. Lunar months are dependent on the cycles of the moon. One month is considered the time it takes for two occurrences of the same cycle to occur, such as two new moons or two full moons.
One moon is generally one moon as the time it takes for the moon to revolve around the sun is 29 or 30 days. Therefore, two moons are approximately two moons.
Venus has no moons at all, not even one.
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.
Mercury and Venus. These two planets have no known moons.

No. There are two New moons, on the 1st and 31st of the month,and one Full Moon, around the 16th and 17th.
A Blue Moon, that is if you mean two full moons in one 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!
one month
Yes. This last happened in February 2014.
