Repeating Events and Tasks
Repeating events and tasks reoccur at regular intervals (such as every day, every week, or every month).
To make an event or task repeat, tap Repeat in its Event Details view and then tap a repeat interval: None, Daily, Weekly, Monthly, or Yearly.
note
Unlike the Mac version of BusyCal, the iOS version does not support custom repeats. However, custom repeats set on your Mac do sync correctly to BusyCal for iOS.
