Konstandinos is a name of Greek origin, derived from the ancient Greek word 'konstantinos', which means 'constant' or 'steadfast'. This name has been popular throughout history and has been borne by many notable figures, including several Byzantine emperors. In the Orthodox Church, St. Constantine the Great, known for his role in the spread of Christianity, is celebrated on May 21st. Today, Konstandinos remains a respected name in Greece and among the Greek diaspora worldwide. It is often shortened to Kostas or Kostandin in daily use, but its full form lends an air of dignity and tradition.
"Konstandinos was quite popular among parents in the late twentieth century, with peaks in popularity in 1973, 1992, and 1999. However, its appeal seemed to wane slightly by 2009, as there were only five births that year."
