Hello

I'm writing a Date-class in C++ and I need algorithms for
calculating different stuff.
E.g. 
	- given an certain date I must calculate
		the number of the week
		which weekday it is
		which month
		etc. etc.
	- adding of dates
	- adding years, months or days to a date

	etc. etc.

Any pointers would be very helpful.

Thanks
	Johan
