Handcuff Day
Handcuff Day is observed on February 20th to mark the anniversary of the patent for modern handcuffs, which was granted on February 20, 1912, to George A. Carney. His design introduced the adjustable ratcheting mechanism still used today, making handcuffs more efficient and secure.

Hoodie Hoo Day
Hoodie Hoo Day is a quirky, good‑natured holiday celebrated every year on February 20th in the Northern Hemisphere. Its purpose is simple: chase away winter and welcome the coming of spring by stepping outside at exactly noon and shouting “Hoodie Hoo!” with hands raised high. Hoodie Hoo Day was created in the late 1980s by Thomas and Ruth Roy of Wellcat Holidays, known for inventing dozens of humorous observances. Thomas Roy originally submitted the holiday to Chase’s Calendar of Events while working as a radio host; it was accepted, published, and eventually picked up by national media, helping it spread across North America. The date—February 20th—was chosen to fall exactly one month before the spring equinox, giving people a symbolic way to shake off the winter blues.
