Kick Day, known as किक डे in Hindi, is observed on February 16, the second day of the informal "Anti-Valentine Week" that follows the romantic Valentine's Week. Like the rest of the week, it isn't tied to any documented historical event; it's a pop-culture tradition that spread through greeting cards and, later, social media.

True to its name, it's framed humorously around "kicking away" bad habits, negativity, or a difficult relationship, mostly expressed through jokes, memes, and playful Kick Day Shayari shared between friends rather than anything literal.

It's primarily popular in India and parts of South Asia, where the full seven-day Anti-Valentine Week sequence — Slap, Kick, Perfume, Flirting, Confession, Missing, and Breakup Day — is a well-known, if unofficial, tradition among young people. Sharing a witty Kick Day Status update is a common way to mark it online.
