There have been questions about this, so here’s a thread to follow the discussion.
Q: So how do I set a min or max date for do allow user to select dates only from a certain range?
A: In the current version (1.0.0) you can’t, unfortunately. The good news is that the feature is on the backlog (see
https://github.com/vaadin/vaadin-date-picker/issues/30
) and will be available.
Until then, you need to stick using a custom validator:
