Hide/show block by condition (registration time)?

Question

WordPress

Good day to all. There was a task to remove a block on the Wordpress site for one week only for those who registered on Wednesday after 17:00 . I understand that there is a robot with php dates. Tell me who has come across or knows how to solve (I will be grateful for examples, links).

Answer 1

$t = get_userdata(get_current_user_id());
echo $t != 0 ? 'user registered: '.date("d.m.Y",strtotime($t->user_registered)) : 'user not logged in';

and then you will figure out how to use IFs yourself)
