Allow empty date on initialize

[oanacrisan]

I'd like to have the possibility to not set an initial date value, but still have the datepicker set to current month when I click on the input to open it. Otherwise, if the date is null, the days are not displayed. And the reason I do not want to set the date with new Date() on initializing is that I do not want the date (of today) displayed in the input, I'd prefer for the input to be populated only after the date is selected.

Maybe in init method have something like this:
const start = startOfMonth(this.date || new Date()); and const end = endOfMonth(this.date || new Date()); so that days get computed even if date is not set.
