Anto's name day is January 17 in Estonia.
Anto is a relatively rare name in the USA, primarily used as a diminutive of Anthony or Antonia, but gaining traction as an independent choice. It’s more popular in Europe, particularly in the Balkans and Estonia, where it’s often a given name in its own right. The name’s origin is as a shortened form, lacking a distinct etymological history of its own. It’s generally considered unisex, leaning slightly masculine, with usage varying by region. Anto evokes a modern, approachable, and quietly confident vibe. Its simplicity and adaptability contribute to its growing appeal.
