Workflow Birthday Reminder

Hi Everyone,

I have a Calendar and Contact List , both have the Birthday field that input format is "Date / Time" , and also Title For the Calendar and the Name of the Contact on the list.

The Workflow should be automatically started once someone update or create a new item in the contact list, and after that step it should update the Calendar List according to what is inserted, meaning update the "Event Title" as one would call it , ie , "Jimmy's Birthday" and should be an all day event and should re-occur yearly on the same date on the calender

I'm using SharePoint Designer 2013 with SharePoint Online 2010 Enterprise E3 and the last step is where I'm stuck to add / update the Calendar List.

Any help would be greatly appreciated.

Thanks in advance.
