When Apple released iOS 7 late last year, the overhauled user interface included tweaks and changes throughout the entire operating system.
One such change was the removal of the ability to view your daily agenda from the month view in the Calendar app. As it was in iOS 7's month view, you simply saw a dot on each day where something was scheduled. To view the agenda, you had to tap on the day, opening another screen. This lead to a lot of tapping and navigating just to view your agenda for multiple days within a given month.
