I started the Google Calendar Redesign project last November, because I felt that the interactions were not intuitive. When I envision the calendar, I think of a very simple interface that works with gestures which are easy to relate to and present the information in a manner that is easier to understand and interpret. Then, Android L came along, and it was amazing! But I still had those ideas in my head and I decided to go ahead with the redesign anyway.
The redesign follows the material design closely but not fully and might even violate some principles. The idea was to look at existing interactions in a new light.
A lot of changes occured to the design because of the introduction of Android L and the design changes it brought to the google calendar. I have omitted some of the initial sketches because they look really bad when compared to the android L version of Google Calendar.
