How to automatically update h1 in posts

Hi all,

I use a shortcode to automatically update the year of all my content, but title of posts do not allow this shortcode, so basically they do not change.

I have hidden title and modify an h2 as h1 so this is sorted, but I would prefer another option, leaving just one h1 and not hiding title so that google accepts my website (once I index it, as it’s still in progress).
