The global social media holiday was first recognized on April 16, 2010. Nate Bonilla-Warford, an optometrist from Tampa, Florida thought of the idea after thinking about a simple calculation with “Foursquare”. Bonilla-Warford thought up the idea to “check-in” to Foursquare on the 4th month and 16th day of the year. After contacting the Foursquare headquarters in New York City about the idea, the company officially declared April 16 “Foursquare Day.”
