National Find a Rainbow Day – April 3, 2025

April showers are going to bring more than just May flowers. On April 3,  we get to celebrate National Find a Rainbow Day. Rainbows have always felt somewhat magical to us. And who can blame us? Rainbows are beautiful and a little mysterious.

On this colorful holiday we can really find time to explore and relish in one of nature’s greatest beauties.

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.

What Are Rainbows Made Out Of?

When water droplets in the air come in contact with the light from the sun, the reflection of light is refracted in the water droplet and shows the color spectrum we know as the rainbow.

How Do You Find a Rainbow?

It doesn’t matter what area you’re in as long as there is sunlight and a slight mist in the air you should be able to see a rainbow. Face the horizon with your back to the sun and you should be able to find it.

Are Rainbows Symbolic?

Rainbows have been used in mythology, in the bible, and more mystical tales. Some people and religions believe that rainbows are lucky. Rainbows are for sure gorgeous and we wouldn’t be surprised if they were a symbol of something greater.

  2. 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!

5 Facts You Didn’t Know About Rainbows

  1. 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.

  2. Rainbows Are Actually Circular

    Full circle rainbows can only be seen from the air. The ground interferes and gives it a more arc shape.

  3. There is a Goddess of Rainbows

    The Ancient Greeks actually had a goddess dedicated to rainbows named Iris. Her Ancient Roman name is Arcus.

  4. 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.
