I should update this version of Hugo and get myself using archetypes to create new posts ...
Then I won't have to manually set the date every time.
...
OMFG, it works already. I no longer need to set the date. See false.
hugo new --kind post content/posts/2021-02-25-bleh-bleh.md
And now I no longer need to trim out the date at the start of the title.
