Here is the render of the deprecation notice: https://41969-1385122-gh.circle-artifacts.com/0/doc/build/html/api/next_api_changes/deprecations/17983-JMK.html#functions-epoch2num-and-julian2num-use-rcparams-date-epoch-default-1970-01-01t00-00-00

Note that julian2num doesn't actually appear in our docs, but its in dates.py.

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

$ git checkout v3.3.x
$ git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

$ git cherry-pick -m1 4b179b92c0fa100a2ebea3a80aadf4fc59b8d14d

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

$ git commit -am 'Backport PR #18021: FIX: update num2julian and julian2num'

4. Push to a named branch :

git push YOURFORK v3.3.x:auto-backport-of-pr-18021-on-v3.3.x

5. Create a PR against branch v3.3.x, I would have named this PR:

"Backport PR #18021 on branch v3.3.x"

And apply the correct labels and milestones.

Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon!

If these instruction are inaccurate, feel free to suggest an improvement.
