What is the exact date for the founding of Rome?

The founding of Rome is traditionally dated to April 21, 753 BC. This date is derived from ancient Roman historians, particularly Varro, who calculated the founding year based on various historical accounts and mythological traditions. According to legend, Romulus and Remus, the twin brothers raised by a she-wolf, founded the city of Rome after Romulus became the first king. The significance of the date is also celebrated annually in Rome as Parilia, a festival honoring the city's founding.

The choice of April 21 aligns with these historical traditions and is recognized in both Roman history and legendary narratives. Other dates mentioned, such as March 15, 44 BC, are crucial in Roman history for significant events like Caesar's assassination, while January 1, 509 BC, marks the traditional establishment of the Roman Republic, distinct from the founding of the city itself. Thus, April 21, 753 BC, remains the most widely accepted date for the founding of Rome.
