Date returned as string

Hello I’m try to figure out how to convert date from the following api

[jsoncontentimporter url= "https://www.bikereg.com/api/search?region=Rocky%20Mountain" basenode="MatchingEvents"]
{MatchingEventsID}
<a href="https://www.bikereg.com/{EventId:urlencode}">{EventName:unique}
{EventCity}
{EventState} 
{EventDate}

[/jsoncontentimporter]

Any help would be greatly appreciated

Thanks
