algebra cleanup in FY5253 and Easter offsets
State: closed

Same types of cleanups you've gotten used to seeing elsewhere, now applied to FY5253 and Easter.  This should be orthogonal to others.

I think there's one more algebra/cleanup after this, then we're jumping into bugfixes.
I doubt we have very many tests for this. @gfyoung can you have a look and see if the changes look ok.
@jreback : I'll take a look later this evening.  If all looks good, can I just merge this?
yep
#14774 has a use case that hits one of the existing `assert False` statements (i.e. not one of the ones discussed above for coverage checks).  I'll take a look at that after this gets closed.
@jbrockmendel : Merged and closed.  Thanks!
CI: revert back to dateutil released as many changes

This reverts https://github.com/pandas-dev/pandas/pull/18193. The problem is there is something wrong with the upstream version such that errors in the code don't get reported.

@TomAugspurger I identified the source of the problem: https://github.com/ipython/ipython/pull/9823 So another option is to pin IPython to an older version (although I would maybe rather vendor the latest upstream version + bug fix, to mimic that we are using the latest IPython version)
I opened an issue at IPython: https://github.com/ipython/ipython/issues/10904 (with potential solution)
Thanks for tracking it down @jorisvandenbossche. I think reverting https://github.com/pandas-dev/pandas/commit/ca737aca8b73b10b617f7fcc7da35545f9ec0a89 for now is fine. And then once the next IPython is released with your fix, we'd require it for building the docs.

BUG: Use total_tie_count to normalize dense ranking
State: closed

- [x] closes #18296
- [ ] tests added / passed
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [x] whatsnew entry

As reported in #18296, for a `Series` with repeated values, `Series.rank(pct=True, method='dense').max()` may not be `<=1` as expected.

This is due to the division of the ranks by the total number of elements in the `Series`, instead of the maximum rank assigned. Here we update the calculation.

I've confirmed that the updated code gives the expected result from the example in #18296.
