Yes - apologies for the noise.

I think this is basically a duplicate of request 1922 then.

I see, so the next month would include both its 4th friday, and the 
previous months 4th friday, and you'd end up with two events in the 
same month.
The recurrence I'm after is the nth x-day of the month, including the 
possibility of counting backwards from the end of the month (which 
would provide the 'last friday' functionality). It would be very 
useful, perhaps I'll have a look at the code. I'm not a programmer 
though, so I doubt I'll be able to do it!

This isn't quite true, though I agree that the way that "same weekday" 
recurrence works is confusing. Sometimes months have a 5th Friday, for 
example, and sometimes they don't. I think what happens is that we're 
going based on week number, so the month has a 5th week, but Friday 
isn't in it.



I guess we could try to check for that case; I'm honestly not sure how 
hard it is. However if what you want is the last Friday of a month, 
that's a different kind of recurrence that's not implemented in 
Kronolith (see ticket 1922).

When creating an event and specifying 'Monthly: Recurs every x 
month(s) on the same weekday' the event will actually recur every 4 
weeks, not every month. This leads to (for example) an event set to 
recur on the last Friday of a month sometimes occurring twice in a 
month.
