Thanks for the super quick answer! This got me on the right track
I found a helpful forum post that I built on:
Here’s the page model:
<?php
class EventPage extends Page {
public function year() {
return $this->eventdates()->toStructure()->first()->eventdate()->toDate("Y");
}
}
And in the pages/Pagetable section, simply:
text: "{{ page.year }}"
Hooray! Thank you!
