There are an abundance of uncommon holidays in April. Whether you prefer to write mysteries or romance, thrillers or fantasies, science fiction or historical fiction, I'm sure you can find one of them that catches your eye and causes storylines to start running through your mind.

Will you see a rainbow on Find a Rainbow Day? Are you going to wear tweed clothing on Tweed Day?

Find a Rainbow Day - Rainbows are beautiful bands of light that appear in the sky when the sun is shining while it is raining. Red, orange, yellow, green, blue, indigo, and violet are the colors displayed in these bands of light. These breathtaking exhibitions that appear in the sky have been around since the beginning of time.

There are several many beliefs about rainbows. Did the rumor that a pot of gold can be found at the end of the rainbow start in Ireland with the leprechauns? Actually this belief began in Silesia, an obscure part of eastern Europe that is now located in Poland. A pot of gold is believed to have been placed at the end of the rainbow by angels. The only person who can retrieve this treasure is a nude man. Hmm.

Is it possible to walk underneath a rainbow and come out on the other side? Well, according to the laws of physics, this just cannot be done. While your back is to the sun the rainbow is always in front of you. Legend has it, though, that if you do succeed in passing underneath the rainbow you will be transformed – from a man into a woman or from a woman into a man.

For Find a Rainbow Day, pick one of the above beliefs about rainbows and write a fictional story about it. Or do some research and discover what other strange beliefs about rainbows exist and write a story about one of them.

Tweed Day - Does this day celebrate the thick, woolen, twill styled material that many jackets, suits, and slacks are made of? Or does it celebrate the NYC politician Boss Tweed who stole millions of dollars from New York City? What do you think? My opinion is that it celebrates the warm, woolen clothing that originated in Scotland.

You could write an historical fiction story about Boss Tweed and his corrupt methods, or you could write an historical fiction story about how tweed material was first made.
