Calendar localisation

[TimWillebrands]

Hi there,

We're using the Calendar component in an app of ours, but an issue we have is that the week in this component starts at Sunday. Here in the Netherlands people are used to weeks starting at Monday so it's a bit unintuitive for our customers.
Is there a way to make the Calendar's weeks start at a different day of the week?

If this isn't supported we would be willing to contribute
