@humptydumpty I'm not entirely clear but this might not be the best approach copyright protection-wise.
If content is authored in previous years, arguably it should state the original publication year.
Otherwise a 3rd party could have the same content with an earlier claim date, and superficially their claim pre-dates yours as original author.
I've seen people do something like (c) MYCOMPANY 2013-2023 to preserve rights ref previous periods.
But I'm not an intellectual property lawyer, so I am not 100%.
