Event Date instead of days

Hello people,
it is possible to make generally show at the event Overview instead of the days the date.
If so, how
can someone help would be great

I've been under modules / boonex / event / templates / base the
wall_outline_extra_info.html to expand with __event_start__ ect.
but unfortunately it did not work
I would like to display the day away and instead insert the date of the event
