Hi.
1. Week(^{2005/01/01},3,2) Returns 52
2. Week(^{2005/01/02},3,2) Returns 52
3. Week(^{2005/01/03},3,2) Returns 1

Surely 1 & 2 above are returning an incorrect week no.
The second parameter indicates Seven Days, the third to start on a Monday

Its probably because it considers it as Week 52 of last year (?) but the fact that I have 2005 in the year , should'nt this return a zero ?
(.i.e the 1st and 2nd of Jan 2005 dont belong to any week IN 2005 if Monday 3rd is the first day of the year)

Regards,

Gerard
