There is a calendar here
In this example, two calendars, the second restricts the choice of not less than the date of the first ...
Question: how to make in the first calendar a choice restriction min value = (current day + 1day), and in the second - min value restriction = (result of the first calendar + 1day)?
If today is 08.09, then you can choose from 09.09, if 09.09 is selected in the first, then dates from 10.09 are available in the second
