How to get current year in a Nunjucks template within Apostrophe CMS

I am in the process of adding a copyright line to the footer of a website that I have been working on and I cannot find the best way to get the current dynamically into the footer so I never have to set it again. I have tried multiple things, including a global setting that can be accessed from anywhere, but nothing has worked.

Any feedback would be appreciated. Thanks.

Write an ApostropheCMS nunjucks helper function. See those docs for the general issues around this. Your specific function could look like:

self.addHelpers({
  thisYear: function() {
    return new Date().getFullYear();
  }
});

If you put that in construct of a module of your own, let's say it's called helpers, then you can call it in Nunjucks as {{ apos.helpers.thisYear() }}.

These are very handy, just remember they cannot do any async work.
