I would love to see this functionality:

Recurring evens are great. But sometimes you want to have a recurring event on every first Sunday of the month unless that Sunday is on the 1st (or maybe the 1st, 2nd or 3rd, etc) of the month. Same goes for last Thursday of the month, maybe you don't want the event if said Thursday is on the 31st.

Additionally, it would also be handy to be able to create a recurring event each time a specific day falls on a specific date. Every Tuesday the 7th for instance.

All just examples but hopefully it's understandable what i'm looking for.

Hmm... sounds quite complex. I'm not sure if the iCalendar standard supports such recurrence patterns or if it's possible to create a GUI that a normal user can use. It's probably easier just to manually create an exception date on such days.

I see, I'm surprised that it might be too complex.

Hello! Today I happened to use the recurrence of event and I am very disappointed that I could not set an exact date of recurrence. Is it possible to insert a specific day for set to repeat? For example, at the moment an event is on the February 26th and I would like the recurrence - on 15 March.
I hope it will be an easy too

And which would be the recurrence between these two dates? Could it be more specific?

You can set a daily recurrence, repeat it every 17 days (number of days between 2/26/2013 and 3/15/2013) and repeat only 1 time.

Yes, this is an option, but is not too convenient to calculate the days when a repeat is after few months. I think it would be nice when a small calendar appears to choose the date
