Is there something that starts timer to make an action?

Is there something that starts timer to make an action?

Is there something, that puts a timer for making an action after days, in
php.
Like if I have blocked users table in DB... I've put it to the table, and
let's say I want to remove it from blocked user table after 5 days... is
there something that automates it???
Hope I asked correctly and you understood my thought
