National Frog Jumping Day is an annual observance held on May 13th, encouraging people to engage in frog jumping activities. This holiday traces its origins to a Mark Twain story depicting a contest between two men, betting on whose frogs could achieve the highest jumps, featuring a pet frog named Dan'l Webster. Interestingly, Twain didn't create this tale; rather, he heard it at various mining camps before immortalizing it in writing.

Originally titled "Jim Smiley and His Jumping Frog," the story was later published as "The Celebrated Jumping Frog of Calaveras County." Given its connection to this narrative, the day serves as an ideal opportunity for competitive frog jumping with friends. Whether you're up for the challenge or prefer spending the day learning about frogs, the choice is yours!
