What Day Was the launch of Facebook (TheFacebook)?

About this date

Mark Zuckerberg launched "TheFacebook" from his Harvard dormitory room, initially restricted to Harvard students before expanding to other universities and eventually the general public.

The platform later dropped "The" from its name and grew into one of the most-used social networking services in the world.

The platform's original Harvard-only restriction required users to have a valid harvard.edu email address, a deliberate gating strategy that shaped its early exclusive, campus-by-campus expansion model.

Zuckerberg has said the site's original code took him about a week to write, a rapid development timeline that has since become part of the company's own founding mythology, later dramatized in the 2010 film "The Social Network."

The site's original registration process required users to affirm their real identity using a university email address, a founding design choice that shaped the platform's later, broader real-name policy as it opened to the general public.
