Does anyone actually trust the Moon is going toturn green ? I do n’t know . But I ’m here to give you the devastating news show that on April 20 , there will not be a “ Green Moon ” .

This “ hoax ” started back in 2016 , submit that on 4/20 – also known as “ Weed Day ” for reasons – the Moon would turn an odd shade of Green River . Since then , every year , it seems to do the round . Sometimes it ’s also suggest this is the first time this will happen in 420 years .

You probably do n’t need me to tell apart you that it ’s not true . In fact , on April 20 the Moon will be just four days past a new Moon , meaning it ’ll come out as only a crescent of light .

“ My sweet grannie shared this thinking it ’s real , ” one commenter publish onFacebook .

“ I do n’t roll in the hay what ’s funny , the fact that my granddaddy shared this or that it looks like everyone else ’s did too , ” say another .

Yes , I know , it ’s a fleck of a shame . But the Moon does change colour sometimes , during atotal lunar occultation , when it passes completely within Earth ’s shadow ( known as the umbra ) .

In this event it can turn red – often name a “ bloodline moon ” – as the Sun ’s Inner Light travels through more of Earth ’s atmosphere and is thus refracted more towards the red end of the spectrum . It ’s exchangeable to how a sunset or sunrise appears cherry-red on the sensible horizon .

Then there ’s also the “ dingy moon ” as well , although that ’s nothing to do with the Moon turning blue . It ’s ordinarily used to concern to the second full moon in a single calendar month . Last month , we even had asuper downhearted profligate lunar month , just to confuse subject .

According toSnopes , the green moon hoax first arose on Facebook in 2016 , claiming that it would occur on May 29 , 2016 . The poster said it would turn fleeceable due to Uranus look near the Moon .

“ The immature giant is only 4 degrees away from the synodic month , ” they indite . “ The cosmic uneven - couple will appear about four stage aside in the sky – equal to 8 full moon side - by - side . ”

Since then it has evolved passably to involve “ several major planet ” aligning , and now occurs on April 20 . A commonly shared image proclaims it will stay green for 90 bit .

Sadly , the Moon wo n’t be deform green . But there are plenty of other literal uranology events hap in 2018 . you could look into some of them outhere .
