History of National Find a Rainbow Day
Rainbows are caused by the reflection, refraction, and dispersion of light in water, resulting in a visual spectrum of light appearing in the sky, taking the form of a multicolored arc. They always appear on the side of the sky directly opposite to the sun.
Don’t go chasing rainbows, because they’re not necessarily located at a specific distance from where you observe them. They’re an optical illusion viewed from a certain angle to a relative light source, meaning the closer you try to get, the further away it goes. Even if you see someone who appears to be standing right beneath the rainbow, they’ll see a different rainbow further off into the distance. In the words of Kermit the Frog, “Rainbows are visions, they’re only illusions, and rainbows have nothing to hide.”
In 1979, Paul Williams and Kenneth Ascher wrote the iconic “Rainbow Connection” performed by Kermit the Frog (Jim Henson) in The Muppet Movie, creating many young children’s and adults’ new favorite song. Henson told them that the opening scene should feature Kermit sitting by himself, playing a banjo and singing. Williams and Ascher wrote the majority of the song fairly quick, but got stuck on the chorus. While explaining to Williams’ then-wife, Kate, over dinner their predicament, they said they needed a phrase that would “provide a rainbow connection.” However, while explaining it, they realized that “rainbow connection” was the exact phrase they needed. Basically, rainbows are more than science — they’re pretty magical too. That’s the rainbow connection.

National Find a Rainbow Day FAQs
When is National Find a Rainbow Day?
In 2027, National Find a Rainbow Day is observed on Saturday, April 3, making it an ideal weekend for outdoor adventures and seeking out vibrant arcs after the rain.
How do rainbows form?
This optical phenomenon requires specific conditions: sunlight behind the observer and water droplets in front. Each droplet refracts and reflects light, creating the spectrum of colors we see, with the angle of the sun and rain determining the rainbow’s position and visibility.
How rare are rainbows?
Their appearance is tied directly to weather patterns, making them more common during periods of intermittent rain and sunshine, such as spring or late summer. Catching one often feels like a special, serendipitous moment.
What colors are in a rainbow?
While traditionally seven colors are listed, the spectrum is actually continuous, with colors blending seamlessly into one another. The distinct bands we perceive are a result of how our eyes interpret these different wavelengths of light.
National Find a Rainbow Day Activities
Try Finding a Rainbow
A slightly humid but sunny day is the perfect day to find a rainbow. Try standing with your back to the sun and looking to the horizon and hopefully you'll get to see a majestic rainbow!
Make Your Own Rainbow
Maybe the day is too sunny and you just can’t seem to find a rainbow. Don't worry you can make your own! A light mist from the water hose at a certain angle that catches the sun can create its own rainbow. You can also try making tie dye shirts or rainbow colored cupcakes, just to sprinkle some color into your day.
Celebrate LGBTQ+ Events
Rainbows are a source of pride and expression for the LGBTQ+ community and if you can’t find a rainbow in the wild, then celebrate your pride or be an ally.
5 Facts You Didn’t Know About Rainbows
Double Rainbows Are Real
Technically all rainbows are double rainbows, we just can’t see the second arch because it is more faint. If there's more water we’ll see the second arch creating the double rainbow effect.
Rainbows Are Actually Circular
Full circle rainbows can only be seen from the air. The ground interferes and gives it a more arc shape.
There is a Goddess of Rainbows
The Ancient Greeks actually had a goddess dedicated to rainbows named Iris. Her Ancient Roman name is Arcus.
The Refraction is Exactly 42 Degrees
When light bends the water droplets in the air at exactly 42 degrees we get to see a rainbow.
