Add \date{}
to share/jupyter/nbconvert/templates/latex/base.text.j2
anywhere before /maketitle
(e.g. before the title
block)
If you want to control it using the notebook metadata, add this instead:
((* if nb.metadata.get('nodate', false) *))
\date{}
((* endif *))
And add "nodate": true
to the notebook metadata
