National Adopt A Shelter Pet Day was founded by Colleen Paige to highlight the approximately 6.5 million animals entering U.S. shelters annually and encourage adoption over buying from breeders. International Jazz Day was established by UNESCO in 2011 at the initiative of pianist Herbie Hancock, observed with concerts and education events in more than 190 countries. Honesty Day was created by M. Hirsh Goldberg, author of The Book of Lies, positioning April 30 as the antidote to April Fools’ Day. National Arbor Day was founded by J. Sterling Morton in Nebraska City, Nebraska — the first Arbor Day on April 10, 1872 saw an estimated one million trees planted, and the last Friday of April remains the national observance. A kennel, a horn, a truth, and a sapling.
