When does the opening scene take place? What holiday is it?

Is this answer correct:
The opening scene takes place about 44 BC. It is February 15, the feast of Lupercal. This holiday celebrates fertility and honors the god Lupercus.

Ides of March

Thanks

wait, how can it be the ides of March when the feast of Lupercal is in February?

Roman citizens wandering the streets, neglecting their work in order to watch Julius Caesar’s triumphal parade: Caesar has defeated the Roman general Pompey, his archrival, in battle. The tribunes scold the citizens for abandoning their duties and remove decorations from Caesar’s statues. Caesar enters with his entourage, including the military and political figures Brutus, Cassius, and Antony. A Soothsayer calls out to Caesar to “beware the Ides of March,” but Caesar ignores him and proceeds with his victory celebration

But it is not yet the ides of March. A soothsayer is like a fortune teller. In Act1, Scene 1, it is February,right?
