I think that I figured out a good system: Posts will remain as such. I set their published_date attribute to 2019-09-16 16:03, which is the date and time of Herman’s oldest post. (Don’t judge me. I just needed some kind of significant value for all posts.) On the website itself, I hid the date in the posts via CSS. For each tag, I will then have a page that embeds the corresponding post list, from which I will also hide the date. This way I can make my posts more timeless. I already published the first one.
