APRIL FOOLS' DAY
April Fools' Day on April 1st has long been a day when practical jokes and tricks are played on the unaware. It's a time when children convince their parents they've broken a bone. Parents get in on the planning, too. #AprilFoolsDay
NATIONAL TOM FOOLERYS DAY
April 1 is National Tom Foolerys Day on the National Day Calendar, and we are celebrating with harmless pranks, silly tricks, shenanigans, and, of course, tomfoolery. April 1 also happens to be the birthday of Tom Foolery, a character developed by Kalahari Resorts, home to America’s largest indoor waterparks. This is no April Fool’s joke! We are dedicating an entire day to celebrating the spirit of adventure, play, and a little bit of trickery, in all of us. #TOMFOOLERYSDAY
PASSOVER BEGINS
Every year, the spring festival called Passover is celebrated for 8 days. Traditionally known as a major Jewish holiday, many Christians have also begun to take part in celebrating Passover. The date of the festival is in accordance with the first full moon in the Hebrew calendar month, Nissan. For this reason, the date changes every year. #Passover
