Whoa, that was not the most minimalist. Up here in Sweden, where week numbers are very much standard in planning, we use [1] (which, translated, means "week now").
Of course, Google's calendar also shows it which is handy.
I agree that vecka.nu is better on the minimalism, but every now and then I have to use the functionality to find out what week number a particular date is in.
