As the old saying goes, April showers bring May flowers. But showers are far from the only notable happenings during the month of April.
In fact, there are dozens of spring holidays, observances, awareness weeks and seasonal observations to note on your 2025 calendar and we've got them all in this comprehensive list of April holidays below.
Along with a little rain, April ushers in some of the biggest holidays of the year, including April Fools' Day, Easter, Passover, Arbor Day and Earth Day.
But those are just the beginning of the many important dates in this 30-day month. Along with those marquee holidays, April brings a host of others, including fun observances like Find a Rainbow Day, World Party Day, Pajama Day, National Scrabble Day, Hairstylist Appreciation Day, Denim Day and Tweed Day for starters.
There are also a variety of food holidays to savor including Oatmeal Cookie Day, National Gummi Bear Day, Cherry Cheesecake Day, Deep-Dish Pizza Day and Burrito Day to name a few.
There are also more serious recognitions throughout the month including Marine Mammal Rescue Day, National Adopt A Shelter Pet Day, National Fun Day, as well as World Autism Awareness Day, Paraprofessional Appreciation Day and World Health Day.
Finally, you'll also find a comprehensive rundown of monthly observances in April that cover stress and financial literacy to astronomy and jazz.
