Full Pink Moon

This full Moon heralded the appearance of the moss pink, or wild ground phlox (one of the first spring flowers). It is also known as the Sprouting Grass Moon, the Egg Moon, and the Fish Moon. Historically, Native Americans living in what is now the northern and eastern United States kept track of the seasons by giving a distinctive name to each full Moon. This name was used to refer to the entire month in which the Moon occurred. With some variations, the same Moon names were used throughout the Algonquian tribes from New England to Lake Superior.

Analysis: According to the Old Farmer's Almanac, "Full Pink Moon" is indeed one of the traditional Native American names for a full moon that occurs in April. Lest there be any confusion, however, the nickname does not refer to a full moon that is literally pink in color. It was inspired, the almanac says, by the springtime bloom of the moss pink flower (Phlox subulata), commonly found in the central and eastern United States.
Coincidentally, a total lunar eclipse will also occur during the full moon of April 15, 2014, which means that for some observers it will actually take on a dull red or rusty hue as the earth's shadow passes across the moon's face (which is why a total lunar eclipse is sometimes referred to as a "Blood Moon"). So, while we wouldn't normally expect a "Pink Moon" to look different from any other full moon, color-wise, this year's occurrence promises to deliver a special treat for the eye — not exactly a bright pink glow, mind you, but almost!
The April 15 full moon is also the "Paschal Full Moon" of 2014, defined in Christian tradition as the first full moon after the vernal equinox. Easter is always celebrated on the Sunday immediately following the Paschal Full Moon.

 

The word lunatic comes from the Latin luna, because it was believed that people were more likely to exhibit aberrant behavior during a full moon. Although studies have been done showing that emergency room visits and accidents are increased during the full moon period, there has yet to be conclusive evidence for causation.
(but, the moon seems to have an effect on animals as well as people.)
