Dear all,

for a weekly data set, the accessor $obsmicro returns the day instead of the week.

Yes, that is according to the spec (=expected).

I would have expected that for this frequency the "micro"-frequency should refer to the calendar week.

Well, apart from the fact that it is documented (see above), the ISO date format and general usage has year/month/day. So week would be another animal.

I know in Germany we have these "KW" (calendar week) numbers, but I'm not sure if something like this is usual internationally.

Obviously one could write a hansl function to count and produce the week numbers. Perhaps by cumulating the output of the seasonals() function or something. But of course that's more complicated.
