The Sunday after 1st January is the beginning of week 01.  This makes
a difference when the year begins on a Sunday.

Ditto.


	   U_weekno = (yday + (7 - (7000 + yday - wday) % 7)) / 7;
	   W_weekno = (yday + (7 - (7001 + yday - wday) % 7)) / 7;

U_weekno = (6 + yday - wday) / 7;
W_weekno = (6 + yday - (wday ? wday - 1 : 6)) / 7;
