TypeError: can't compare offset-naive and offset-aware datetimes

The issue is most likely the usage of date: yyyy-mm-dd without any timezones or time in general.

Note: Only mkdocs build is affected. mkdocs serve runs without any errors reported.

Thanks for reporting. Help appreciated! It's likely the same fix as for #7725. I did not expect this to be such a nuisance to fix. I'm currently short on time, so if anybody has a few minutes on his hands, PR appreciated.

Working on a fix, it appears with draft_if_future_date: true it is still using non timezone aware dates.

PR #7749 out and tested against the repro. I've looked for other instances of datetime and think I've finally got them all.

Keeping open until released.

Released as part of 9.5.47.

Just want to quickly confirm that the CI doesn't error anymore, so this issue really seems to be fixed now.
Thanks for the fix.
