What do you mean by "doesn't work"? I both see and am able to interact with the outside days -

I can't select past dates. Is it previous option "allowPastDate"?

Ah, yes. outside days in this context describes days from the previous and next month that are by default not shown. What you are looking for in this context is isOutsideRange.

From the README:
isOutsideRange indicates which days are out of selectable range. Past dates out of range by default. If you would like to allow the user to select days in the past, you may set isOutsideRange to () => false.

It might be good to (a) add this to the storybook as an example and (b) to actually make the README prop sections linkable. :P
