National Hedgehog Day is observed worldwide every February 2. This unofficial holiday celebrates hedgehogs, small spiny animals belonging to the subfamily Erinaceinae, which are native to Europe, Asia, and Africa. People commemorate the day by sharing interesting facts about hedgehogs, reading books or watching movies featuring them, and playing games like Sonic the Hedgehog. Additionally, individuals may donate to local wildlife rescues that assist hedgehogs, create hedgehog-safe environments in their gardens, and post on social media using the hashtags #NationalHedgehogDay and #HedgehogDay. The origins of National Hedgehog Day are unclear, and it often goes unnoticed due to its coincidence with Groundhog Day.
