public class SerialDateUtilities extends Object
[1] some of the methods assume that the default Calendar is a GregorianCalendar (used mostly to determine leap years) - so the code won’t work if some other Calendar is the default. I'm not sure how to handle this properly?
[2] a whole bunch of static methods isn't very object-oriented - but I couldn't think of a good way to extend the Date and Calendar classes to add the functions I required, so static methods are doing the job for now.
