Answer 1

From: https://docs.oracle.com/javase/7/docs/api/java/util/GregorianCalendar.html

"GregorianCalendar is a concrete subclass of Calendar and provides the standard calendar system used by most of the world..."

Do you need it?
I don't know: depends on the program/application you're creating.
