Not sure it exists (I didn��t find it but it may exists)�� so I did a quick try to code a new method in the class Week.

There is already index but this method returns the index of the current month.

I did something like below (not tested much):

Week>>yearIndex

^ (self dayOfYear / 7 + 1) asInteger

====

DateAndTime now asWeek yearIndex returns 19

Maybe it would be better to create an equivalent method (weekYearIndex) in Date (or eventually Timespan).
