National Find a Rainbow Day

April showers not only bring May flowers, but they also create the perfect rainbow conditions for the month of April. That’s probably why April 3rd is National Find A Rainbow Day—a day in which everyone is encouraged to go outdoors and find a rainbow. What’s going to be at the end of that rainbow? Well, we don’t know, but according to popular legends, there are pots of gold or even other worlds at the end of them. Although that isn’t likely, it’s still a good holiday to head outdoors, get some fresh air and see if you can find your own rainbow.

Unfortunately, we were unable to find any information about who invented National Find A Rainbow Day. However, what we did find was a lot of fun and interesting information about this colorful natural phenomenon. Let’s take a look at some of these rainbow facts before we talk about how this holiday should be celebrated.

Observing National Find A Rainbow Day

Observing this holiday is as easy as going out and looking for the rainbow. However, if it hadn’t rained in a while, it might be difficult to find a natural rainbow, so you might have to make your own. You can do that using a garden hose and some sunlight, or you can buy a prism that splits white light into different colors. You can also spend the day watching The Wizard Of Oz or by making rainbow-themed food. And while you’re celebrating this holiday, don’t forget to use the hashtag #NationalFindARainbowDay to let everyone know you’re celebrating this colorful holiday.
