Calculate week of month in .NET
I need to calculate the week number of a given Date within a month. The reason I embolden month is that all the examples (on here and elsehwere) I come across are based on yearly. Basically, I want to see what week number 14/2/2010 comes in (dd/MM/yyyy format). Given a starting day of Monday, I would expect this to return 2.
How aware of Culture do I have to be in this calculation?
