Hi Anthony,
I think either is okay.
But personally for user experience I prefer your second method.
For people skimming your page they are more likely to be enticed by the event title rather than the date.
But I see your point about the duplicating the date, but I wouldn't worry about it too much, I think it will actually help the user experience, as all the information will be within their eye line without having to make them scroll up to see the date again.
I hope this helps with your decision.
