No founder, establishment record or proclamation has been located for National Sharon Day, and no source explains why it falls on March 7. It circulates on that date through name-day listings and social posts rather than through any sponsoring organization.
From a man's name to a woman's
The earliest Sharon in the English record is a man. The Encyclopaedia Britannica of 1911 carries an entry for Sharon Turner, English historian. His History of the Anglo-Saxons is where the word vikingr first reached English print, in 1801.
The turn toward girls came later, and nobody is certain why. English use as a woman's name dates from the 1920s. Behind the Name suggests it may follow the heroine of Adela Rogers St. Johns's serial novel The Skyrocket, a tenement girl the film version calls Sharon Kimm.
American parents then took it up quickly. Sharon was absent from the Social Security Administration's two hundred most popular girls' names until the 1930s, and by the decade after that it sat eighth.
