There are 42 Gregorian calendar new blue moons in the 20th Century, defined as the second of two consecutive new moons falling in the same month. They occur between the 30th and 31st of the month in the seventh to twelfth degrees of a (tropical zodiac) sign; i.e. from 6d 0m 1s to 11d 59m 59s; typically at intervals of 2-1/2 to 3 years. However four years in this century have two of these blue moons: 1919, 1938, 1957 and 1995. And two such lunations are only some 90 days apart, although in different years: December 31, 1910 and March 30, 1911.
Seventeen of this century's new blue moons are also solar eclipses. A total of eight new blue moons are perigee lunations - a lunation which occurs when the Moon is at or near (within 90% of greater) its closest approach to Earth; four of those alignments also happen to be solar eclipses.
The blue moon of folklore is the second in a pair of full moons in the same calendar month. The new blue moon is little known and even less studied.
There are at this moment only about 6.9 million people now living who were born on the day of this type of blue moon.
