October 21nd Daily Holidays include:

American Frog Day
American Frog Day highlights frogs as amphibians with a long evolutionary history dating back over 200 million years. Frogs belong to the order Anura, a group defined by tailless bodies, powerful hind legs, and distinct vocal abilities. Species vary widely, with tree frogs, bullfrogs, and poison dart frogs representing major categories found across different ecosystems. Their life cycle includes a metamorphosis from aquatic tadpoles to air breathing adults, a biological process studied extensively in early zoology.
