Using a site field value in config

The CMS Questions

Ah, sorry, I had my local copy open, fixed above.

Try:

return [
    // other stuff
    'ready' => function() {
        $delay = site()->delay();
        $lead_time = strtotime('+' . $delay . ' week');
        $day_of_week = date('N', $lead_time);
        $to_tuesday = (7 - $day_of_week) + 2;
        $new_work = strtotime(date('c', $lead_time) . ' + ' . $to_tuesday . ' days');
        return [
           'placeholders' => [
             'new_work' => date('dS F, Y', $new_work),
           ]
        ];
    }
];
