Duplicate an event
Tap or long-press an event to duplicate it. What happens next depends on your [Move or Duplicate via Drag & Drop] setting and the view you’re in.
There are two ways to duplicate an event:
Tap the event to open the detail sheet, then tap [Duplicate]
Open the original event and press the [Duplicate] button in the detail sheet.Long-press the event and choose [Duplicate] from the menu
After long-pressing, tap [Duplicate] in the menu that appears.
