When I see a site with an old copyright date, I think that’s the last time it was updated. So if it says ©2019, I think the site outdated and I don’t trust the information to be current. Okay, that’s a bit severe, but it does look better when the site seems up to date.
Use this code snippet to automatically show the current year in WordPress in a WPBakery block. I have this in a copyright block in the a footer I designed with WPBakery.
{{date|Y}}
This doesn’t seem to work in Elementor.
