Date Arithmetic

Arg,

So I know I use the Calendar abstract class. And I am betting that I use
the Add method.
Could I see a example of some date arithmetic, e.g. number of days from
today since 01/01/1964.

Must I work out the differences by year, month, day individually, convert to
a common unit of time, add them, then convert to a displayable unit of time?

Struggling...

Practice with the GregorianCalendar class and its many online tutirials.

Look at

http://geosoft.no/software/day/Day.java.html

It is a simple API for doing date arithmetics
and finding number of days between dates among
others.
