BUG: dt+BDay(n) wrong if n>5, n%5==0 and dt not on offset (GH5890)
closes #5890

looks good...pls do a rebase on master and can merge it....
 Hi,
When I do "git rebase upstream/master" I get "Current branch bday-addition is up to date."
Not sure if I need to do something more/else?
 sorry

```
git fetch upstrem
git rebase upstream/master
```

see here:

 Yeah this is what I had done before and git is saying the branch is up to date, hence I'm thinking I'm done on my side. Is that correct or do I need to do something more? Sorry for the confusion
  it can't be automatically merged prob a conflict on release.rst

did you push it after?

`git push origin mybranchname -f`?
 you can also try this

`git branch mybranchname -set-upstream origin/master`

it might not be looking at right tracking branch (iow you are rebaseing to your own branch)
 Ah I see thanks. I think it worked this time (I've had to solve the conflicts in release.rst)
 thanks!
