Set date to repeat with rules

I have a calendar on my site, which includes nodes of the type event.

I now want to include the birthdays of registered users in that calendar.
To that I created a rule which creates a node of the type event automatically.

I fill the date with the value I retrieve from the user account creation form, but I cannot set the date files to repeat.
I can only set the start date and end date.

Does anybody know how to set the repeat attributes of the date filed with rules?
