Hi there,
I just found a better solution:
Given a DateList ts, one can split it by calendar months simply using
SplitBy[ts, #[[1, {1, 2}]] &]
instead of my crummy first try.
To split by week, I found a function ISOWeek right in this group (https://groups.google.com/group/comp.soft-sys.math.mathematica/browse_thread/thread/3dbc03f1f113b370/18e87e147589ebfe?hl=bn&lnk=gst&q=week#18e87e147589ebfe), which can then be used analogously like
SplitBy[ts, #[[1, 1]] && ISOWeek[#[[1]]] &]
This kind of stuff makes me love Mathematica! :-)
Thanks to Hans Michel!
Kind regards,
