of course, not all countries have the same definition of week. furthermore, week number does not seem to be so simple.

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).

hth,
