I am looking for a way to extract a week number based on this calendar: http://www.timeanddate.com/calendar/custom.html?year=2014&country=1&wno=1&holm=1&df=1
so eg a date of '2014-12-28 00:00:00.000' should give me week 1 and not 53 SELECT DATEPART (wk,'2014-12-28 00:00:00.000') gives 53
please note that this is not always the same as ISO WEEK
any idea?
Kris
