I have an iPhone 4 and an iPad 3 each running iOS 6.1 (I don't have a Mac). On my iPad I have noticed that in Photos there is a tab labelled Events. This tab doesn't exist on my iPhone. The Events tab is filled with folders named with a date. Sometimes there is more than one folder with the same name.
I haven't been able to find clear documentation on the use of Events.
What is the purpose of Events in Photos? How do they differ from Albums and how do I use them properly.
