That's brilliant, the Chinese Calendar was on my To Do list for 4.1, so you've 
saved me the effort.  Obviously we won't be able to include this 4.0, but it 
can be included in the 4.1 branch when it opens after the 4.0 release.

I'll look at your code at some point over the Christmas holiday break and 
answer your other questions, but I can quickly answer these two.

QDate used to use setYMD(), but this has been deprecated in favour of 
setDate() due to some backwards compatability issues in Qt.  We have just 
mirrored that without there being any difference in how they work.

> 2. for epoch(), what's it?

Epoch is the first date in the calendar system, for example for Gregorian 
Calendar epoch would be 1 Jan 1 AD.  This is different to earliestValidDate() 
which is the first date that the calculation code is valid for, which may be 
the same as the epoch, or earlier or later than it.

Cheers!

John.
