byDay Interval

What do you use as the starting date?

Setting inc to true might help.

If not, can you show the code you use to get the dates? (Please set the dtstart option to your current time so that it can be reliably reproduced.)

Oh that was fast.
The startdate is 01.02.2013.
I use this file to test:

The problem is that you're using a DAILY frequency. Together with the interval, your rule is every third day if it falls on a Monday. If you want every third Monday, the frequency should be WEEKLY. If you want every third Monday of the month, you should go for a MONTHLY frequency, interval of 1, and +3MO.

Ahh I see. The byday rule is just for freq above daily?

In practice, yeah.. there isn't much it's good for with BYDAY.. I mean, it would come in handy if you wanted a pattern like Mon, Wed, Fri, Tue, Thu... And you can still do things like FREQ=DAILY;BYDAY=MO – but you can also do that with WEEKLY.

Yea i see.

Ok I tested it WEEKLY with the sdate on 01.02.2013 and that rule:
FREQ=WEEKLY;BYDAY=MO;INTERVAL=3;UNTIL=20131101T000000Z;WKST=MO
And it starts not on the first Monday it starts on the third.
If I change the sdate to 04.02.2013 (the first Monday) than it works.
Looks like the script asumes that the first week of the Month allready has a booked Monday.
But this Monday is not in this Month and so not booked.
Mhh u know what i mean?

Since the frequency is WEEKLY, it starts in the week of the start date. Since Feb 1st is the Thursday of the previous week, it won't include that Monday. Since you want some special effect with the first date, you'll want to set the start date to the date of your first repetition.
