I couldn't find a way to enter this bug in the maemo bug list, so here it is. Let me know if there is a better place to submit this.
I'm using the latest n900 GPE. Much more features than the built-in calendar.
I have a recurring event created on Saturday, May 21, 2011. It is an all-day event set to recur on the 3rd saturday of every month. This is fine until November. In the November month display, it is shown on Friday, Nov 18 instead of Saturday, Nov 19. In the day views it is not shown at all (does not appear on Nov 18 or Nov 19). On the week view it is shown both Nov 18 and Nov 19.
