Bring on the Rainbows

I've never seen a rainbow in winter, have you? Rainbows seem to be a summertime thing. Why that should be, I have no idea; it's simply a fact of natural life. However, long observation of nature says that the border line between the time of no rainbows and the time when they can be seen is now.

A Japanese calendar, something like The Farmer's Almanac, sets the date of the first chance to see a rainbow as April 15.

It rained all day on April 15 this year. Maybe tomorrow the sun will shine through the clouds. Let the rainbow season begin!
