During the 20th century, there were 229 lunar eclipses of which 83 were penumbral, 65 were partial and 81 were total. Of the total eclipses, 33 were central, in the sense that the Moon passed through the very center (axis) of the Earth's shadow. In the 20th century, the greatest number of eclipses in one year was four, in 1908, 1915, 1926, 1933, 1944, 1951, 1973, and 1991. One month, March 1904, featured two lunar eclipses, on March 2 and March 31. The predictions given here are by Fred Espenak of NASA's Goddard Space Flight Center.
