[Orgmode] Repeat time ranges

[Nicolas Aggelidis]

hi org-users!

i 'am having the following problem. I have some activities that i
organize like this:


* University calendar
** Class 1 <2009-10-12 Mon 15:00>-<2009-10-12 Mon 16:00>

what i want to do, is have this time range repeat itself every week
for 13 occurrences.

Is this possible? at least is it possible to have the time range
repeat itself indefinitely, like with

** Class 1 <2009-10-12 Mon 15:00 +1w>


best regards,
nicolas
