Convert date string to MM DD in react

I have a date string that is returned from API in an object. I need to reformat it so instead of “2022-12-13T06:00Z” it would read “December 13”. The object holds utcStart as “2022-12-13T06:00Z”. Currently the below displays as “2022-12-13T06:00Z”

const eventDates = useRecoilValue(eventDatesState);
return (
    <Grid item xs={12}>
        eventDates.map (data =>(
            <ListItem>
                <span className="date">{eventDates.utcStart}</span>
            </ListItem>
        ))
    </Grid>
)

Since it is in a map function, I don’t know how to do this for each one.This doesn’t work

<span className="date">{new Date(calendarContent.utcStart)}</span>
