OK @MrWook - I made a silly error when copying across the logic for the blank days and have fixed that in a second commit. Should all be fine now.

I'd be grateful if you could have a look through and merge it in to master. Thanks

[MrWook]

Looks good to me. I just found some small issues.
Could you add an example on the example/demo.vue and in the docs docs/.vuepress/components/demo.vue with a settings selector to define the first-day-of-week?

Like always thanks for you contribution! 👍

[mst101]

Thanks for checking this through.
Just a quick question - how would you like me to make these changes in Git? Shall I create a new commit with the changes you suggest, or would you prefer it if I rebased all my changes into one single commit? Or doesn't it matter?!

[MrWook]

You can just create a new commit, i will squash same anyway.

[mst101]

Ok thanks

Would be great to also add this 'breaking change' in the Migration section: https://sumcumo.github.io/vue-datepicker/guide/Migration/
That the prop is replaced with this new prop.

[MrWook]

Hey @sebsobseb i will create a complete Migration guide to get from 2.x.x to 3.x.x
There will be more than this breaking change like the popup which changed the html a little bit and the open improved build process.

@MrWook - how would you like me to proceed with pull requests for:

a) fixing a small bug with the typeable calendar not formatting correctly onblur
b) replacing blankDays with dates from the previous/next months
c) keyboard navigation

Shall I wait until you have merged the current changes into master, or create a new branch from the current status of my first-day-of-week changes?

[MrWook]

@mst101 the best approach is if you make a branch and a PR for each topic.
This way we can have a clean commit history with squash commits which will make the changelog a lot easier to read.

In this repo the example for the demo page and the example demo page is still missing.

If you like you can already start with the other stuff, too. You don't need to wait for me. You just need to keep in mind that you probably need to resolve Merge conflicts this way.

[mst101]

OK thanks - in that case, I'll create a new commit with first-day-of-week examples in this PR and will create new branches for the other changes (and, as you say, resolve any merge conflicts).
