Unknown; likely a phonetic variant of Sade or Chardae
Sharday is a modern American invention, most likely popularized as a phonetic spelling of the name Sade, which rose to fame via the Nigerian-British singer. While Sade is a Yoruba name meaning 'honor confers a crown', Sharday is treated as a distinct creative coinage in the West. It may also be influenced by the French wine region Chablis or the grape Chardonnay, though this connection is stylistic rather than etymological.
