No documented founder or formal establishment record has been verified for National Girlfriend Day. Several self-reported claims circulate, naming different people, different years, and even a different date, and none has been independently confirmed; the observance had settled on August 1 in United States online culture by the 2010s.
Two meanings, sixty years apart
Before "girlfriend" meant a partner, it meant a peer. The earliest print use describes a woman's friend from her youth, a companion rather than a romance. For decades the word stayed there.
The romantic sense arrived later and slowly. Only in the 1920s does the dictionary record "girlfriend" as a man's sweetheart, the meaning that would go on to crowd out the first one in everyday speech. National Girlfriend Day reaches back past that shift, to the friend the word originally named.
