How can I hide the date on blog posts for the Impact Template?

Site URL: http://oshkoshwestbands.com/concerts/2021-spring-concert-1

Hello,

I'd like to remove the post title and date from the header of individual blog posts on my site, which uses the Impact template.  I found custom CSS code to remove the title, but I've been unsuccessful finding the correct code to remove the date.

Does anyone have some insight on how to accomplish this?

Thank you!

(I'd like to remove the date in light gray below.)

Add to Design > Custom CSS

time.Blog-meta-item.Blog-meta-item--date {
    display: none;
}
