Use PowerShell to Get the Number of the Week of the Year

Hello Ed,

this is great! Besides the calculation of the week number, it shows how to extend object in Powershell

what look a bit like deriving sub classes from base classes. One of the major aspects of modern

programming languages! Adding to objects is not the same as deriving from classes, of course. But

at least we don't need to build new objects from scratch if we can add functionality to existing

objects.

That' really good news and well explained in this article!

sorry Mr Ed,

I am afraid that -uformat %V is wrong for the most of us outside US and Japan and maybe another country with gallons and miles :-) .

the msdn pages on Calendar.GetWeekOfYear Method indicate dotnet 3.5 is wrong (buggy) and does not comply to ISO standards.

Dotnet 4.0 seems better if I understand well. But until then...we'll have to calculate.

Keep up the good work.

Why are you making everything into a function lately? I mean, I understand the value of functions, but this seems better suited to a simple script. All the work you did to add members to the script, etc., seem like overkill. I'm sure you're trying to reinforce certain things, but sometimes it seems way over the top. What am I missing?
