International Haiku Poetry Day (April 17) was started in 2007 and later taken on by The Haiku Foundation in celebration of National Poetry Month.
According to The Haiku Foundation, the haiku is an ancient and undefinable-in-English form of Japanese poetry. At its most basic, it is three lines, the first with five syllables, the second with seven and the third with five. Write us a Haiku.
“Haiku are short imagistic poems about things that make the reader feel connected to nature.”
— William J. Higginson (1938-2008), in his essay “Guidelines for Writing Haiku in English.”
