Getting current datetime using Calendar.getInstance() vs new GregorianCalendar()

Question

What might be the difference between getting datetime using

Calendar.getInstance()

vs

new GregorianCalendar()

?

Answer 1

Calendar.getInstance() will give you a Calendar using the default time zone and locale, which can result in a GregorianCalendar, a BuddhistCalendar, or a JapaneseImperialCalendar.

GregorianCalendar will always give you, well, a Gregorian calendar.
