National Animal Cracker Day is celebrated on April 18 in the United States, honoring the iconic childhood treat that has become a nostalgic favorite for many. Animal crackers, which originated from England in the late 1800s, were first commercially produced in America by Stauffer’s Biscuit Company in 1871. The popularity of these animal-shaped biscuits surged when Nabisco introduced their version packaged in circus train-themed boxes, appealing to children who cherished them as both snacks and toys. While Nabisco's animal crackers are known for their sweeter, softer texture, Stauffer’s maintains a less sweet, crisp cracker that resembles a traditional English biscuit. This day encourages people to indulge in these beloved snacks, often evoking fond memories of childhood.
