Week number

[dellarocco88]

I want to be able to print out the current week number, but can find a way to do this.

Week := ???
Gui, Add, Text, xm ym vDate, % "Current week is " Week

Any solution to this?

MsgBox % SubStr(A_YWeek, 5, 2)
Gui, Add, Text, xm ym vDate, % "Current week is " . SubStr(A_YWeek, 5, 2)
