Thanks, but this is my problem. IMHO do we have several calculation 
methods. The US-Method says 1.1.YYYY ist week 1 using DIN week 1 ist 
where the first thursday is in. So you can have 01.01.XXXX in week 52 
or week 53 by DIN but week 1 in US Method. The information when is a 
new week starting is a good thing, because US-week starts on sunday and 
by DIN on Monday.
But after that, what is calculationMethod in Valentina?

Thanks for help
