Should I use GregorianCalendar or Date for a birthday field?

I'm a little bit confused about using the class GregorianCalendar and Date.
What is the difference?

For instance: I have a field in a Person object that represents the date he was born. Do I have to use Date or GregorianCalendar?

What is the best use for them?

Solution

  • If you were writing down the details on paper, would you write down the date of birth as a date, or would you write down a calendar with a circle around the date?

    You would write down the date. Date is a concrete date. Calendar is a tool for working with dates.
