Emília is celebrated as a name day in Hungary on July 19 and in Slovakia on November 24.
Emília is a historically rich feminine name stemming from the ancient Roman family name Aemilia, meaning "rival" or "striving." This spelling is particularly popular in Portuguese, Hungarian, and Slavic cultures, offering a sophisticated variation of Emilia or Emily.

The name conveys a mood of classical elegance and romantic grace, supported by centuries of usage. Classified universally as female, Emília maintains a timeless appeal worldwide.
