Rome's birthday, on 21 April, is known as Natale di Roma. This year the city will celebrate its 2,774th birthday. Traditionally the Eternal City marks its birthday with historical re-enactments of ancient Roman rituals, costumed parades and gladiator fights, however this year, due to Italy's covid-19 restrictions, the festivities move online.

The annual Natale di Roma celebration - known in ancient times as Dies Romana or Romaia - is based on the legendary founding of Rome by Romulus in 753 BC. While there has always been some uncertainty over the year, the ancient Romans were certain of the date Rome was founded: 21 April.
