If you store a date in a field you can always find the month etc from the date.
The now macro is often used to generate dates and the view widget to format dates.
Pickaday plugin helps selecting.
Later I will show how to use edit text widget to select dates

:<$edit-text field=date type=date tag="input"/> {{!!date}}
:<$edit-text field=datetime-local type="datetime-local" tag="input"/> {{!!datetime-local}} datetime local?
