Calendar Application 5c issue

[iMore Question]

I am trying to set up my days off on the calendar without having to input each one. I have a unique schedule in that I work 4 days on and 2 off. It does not give me any sort of option like that uder the "repeat" section.
My old BB did. I m not a computer whiz so am looking for guidance. Thanks in advance
