When is National Find a Rainbow Day?

National Find a Rainbow Day occurs annually on April 3. It’s no accident that this national day falls in the spring.

Springtime frequently brings rain, one of the crucial elements for creating a rainbow. There’s a reason the phrase “April showers bring May flowers” is so often quoted

Let’s learn about rainbows symbolism, how they are formed and some fun facts about rainbows to celebrate National Find a Rainbow Day.

How are rainbows formed?

While it might seem like rainbows are formed by magic and belong in the same category as unicorns and faeries, rainbows are actually made from science and not magic!

There are only two things you need to see a rainbow: water and light. They are most commonly seen right after it’s rained and the sun has come out.

Sunlight looks white, but it actually contains all of the colors in the color spectrum.

When sunlight passes through water droplets still in the air after a rainstorm, the water droplets act as a prism, refracting and reflecting light.

An image answering the question "how are rainbows formed" where white light is shown entering a prism, and then exiting out the other side as the seven colors of the rainbow, with the words "distribution of light" written at the top of the image.

The sunlight is refracted (scattered and bent) through the raindrop, and then reflected back to us.

When reflected back, it appears in the colors of the rainbow: red orange yellow green blue indigo and violet (a handy mnemonic to remember this is Roy G. Biv).

What do rainbows symbolize?

Rainbows symbolize hope. During a storm, things are dark, but rainbows remind us that the dark times will pass, and beautiful things will exist after.

This feeling of calm after the storm ties into the meaning of peace that is also present in rainbow symbolism.

Rainbows serve as a reminder that better days are to come. For this reason, new beginnings are one of the meanings of rainbow symbolism.

Rainbows also symbolize endings, as rainbows are associated with death in many cultures. Rainbows are thought of as a bridge to the afterlife.

In Christianity, a rainbow appears in the story of Noah’s Ark. This rainbow symbolizes the promise God made to Noah: to never again destroy the earth with a flood.

Ancient Greeks and Romans believed that rainbows were a path to the gods. In Greek mythology, there is a goddess named Iris that is the goddess of the rainbow and messenger of the gods.

She is often depicted as the personification of a rainbow. It was believed she could create rainbows, and used them to travel through the sky.

St. Patrick’s Day rainbow

We often associate rainbows with St. Patrick’s Day. This is because rainbows are often depicted with leprechauns, which happen to be one of the St. Patrick’s Day symbols

Irish folklore said that leprechauns were cobblers of the the fairy world. They were paid in gold for their shoemaking and mending services.

In these stories rainbows represented treasure, luck and leprechauns.
