At some point, Zeeman asks employees to enter their birth date. This can typed or selected in the calender. By default, the current day is selected when opening the calender. This is even so when part of the birth date is already typed in.
In this case it would be nice if the selected date is some point in the past (f.e. 30 years ago, 1-1-1990), this would minimise the scrolling needed for all employees and therefore make the calender more useful.
