A Full Pink Moon Is Coming in April

Mark your calendars for Friday, April 19 and get ready to snap some blurry pictures of the sky on your way to work. A full pink moon will appear early that morning, according to a calendar published by The Old Farmer's Almanac.

Considering that the full moon cycle is completed every 29.5 days, the April full moon will be the fourth full moon of 2019. Despite its name, the surface of the moon doesn't actually appear rosy. The name refers to the wild ground phlox, a type of pink wildflower, that tends to sprout in the U.S. and Canada around this time of year. It's also sometimes called an egg moon, fish moon, or sprouting grass moon.

What does the Full Pink Moon mean?

The April full moon might be a bit of a misnomer, but it still plays a pretty important role in the Christian tradition. The date on which the full pink moon appears has historically been used to determine when Easter will be observed. The holiday always falls on the Sunday following the first full moon that appears after the spring equinox. However, if the full moon falls on a Sunday, Easter will be held the following Sunday.

This rule dates back to 325 C.E., when a group of Christian churches called the First Council of Nicaea decided that the light of the full moon would help guide religious pilgrims as they traveled ahead of the holiday. Since the full moon will be visible on April 19 this year, Easter will be held on April 21.

When to see the full pink moon

The best time to view this April full moon is around 4:12 a.m. on the West Coast and 7:12 a.m. on the East Coast. The exact time will vary depending on your location. For a more specific estimate, head to the Almanac's website and type in your city and state or ZIP code.

If you happen to miss this spectacle because you're enjoying a full night’s sleep, don't fret too much. A full flower moon will be arriving in May.

Does the Full Moon Really Make People Act Crazy?

Along with Mercury in retrograde, the full moon is a pretty popular scapegoat for bad luck and bizarre behavior. Encounter someone acting strangely? Blame it on the lunar phases! It's said that crime rates increase and emergency rooms are much busier during the full moon (though a 2004 study debunked this claim). Plus, there's that whole werewolf thing. Why would this be? The reasoning is that the moon, which affects the ocean's tides, probably exerts a similar effect on us, because the human body is made mostly of water.

This belief that the moon influences behavior is so widely held—reportedly, even 80 percent of nurses and 64 percent of doctors think it's true, according to a 1987 paper published in the Journal of Emergency Medicine [PDF]—that in 2012 a team of researchers at Université Laval's School of Psychology in Canada decided to find out if mental illness and the phases of the moon are linked [PDF].

To test the theory, the researchers evaluated 771 patients who visited emergency rooms at two hospitals in Montreal between March 2005 and April 2008. The patients chosen complained of chest pains, which doctors could not determine a medical cause for the pains. Many of the patients suffered from panic attacks, anxiety and mood disorders, or suicidal thoughts.

When the researchers compared the time of the visits to the phases of the moon, they found that there was no link between the incidence of psychological problems and the four lunar phases, with one exception: in the last lunar quarter, anxiety disorders were 32 percent less frequent. "This may be coincidental or due to factors we did not take into account," Dr. Geneviève Belleville, who directed the team of researchers, said. "But one thing is certain: we observed no full-moon or new-moon effect on psychological problems."

So rest easy (or maybe not): If people seem to act crazy during the full moon, their behavior is likely pretty similar during the rest of the lunar cycle as well.

Rare Harvest ‘Micromoon’ Will Appear on Friday the 13th

The first Friday the 13th of 2019 is coming this September, coinciding with a spooky full moon—and that unlucky event will also be a harvest micromoon, Newsweek reports. Here's everything you need to know about the lunar spectacle.

What is a harvest micromoon?

Harvest moon describes the full moon that appears in September. You may have heard that the harvest moon is larger and deeper in color than full moons that appear at different times of the year, but this isn't the case. The name harvest moon has nothing to do with its size or appearance. Many people observe the harvest moon just as it surfaces above the horizon—the time when it looks biggest due to the moon illusion, and reddish or orange-y through the filter of Earth's atmosphere. But as the moon climbs higher in the sky throughout the night, these characteristics fade away—just as they would at any other time of year.

This year, the harvest moon will actually look smaller compared to other full moons. On Friday, September 13, the celestial body reaches its apogee, or the point in its orbit where it's farthest from Earth. It has been dubbed a micromoon, which is the opposite of a supermoon.

When to see the harvest micromoon

Besides its scaled-down appearance, Friday's moon won't look any different from a regular full moon. But its rare conjunction with Friday the 13th makes it an event that anyone with a superstitious side won't want to miss. The moon will achieve maximum fullness at 12:33 a.m. the morning of Saturday, September 14 in the Eastern time zone (earlier the further west you go), but it will appear full and bright the previous and following nights. To catch the mini-moon on the 13th, look up late Friday night in a place with minimal light pollution. And if you want the full harvest moon effect, look to the horizon just after moonrise at 7:33 p.m.
