I worked primarily on the backend of this project, where I began by implementing the CalendarEvent and CalendarEventDatabase (Commit #1). I then created the CalendarDay, CalendarMonth, and CalendarYear classes to better handle the data organization of the Calendar View of events (Commit #2). After that, I added the functionality that would keep the calendarEvents collection and calendarYears (in the CalendarViewModel) in order from earliest event to last event (Commit #3). Finally, I fixed the GetItemsAsync() function (in the CalendarDatabase class) so that it would return a sorted list of all the events previously stored in the database (Commit #4).
