Clicking or tapping the day while in Month view takes you directly to the event-creation screen for that day. If you are in Week or Day view, clicking on a certain time also opens the event-creation screen, with the time you selected as the default start time for the event.
Calendar's live tile cycles through the day's upcoming events, showing you what your day has in store without your having to launch the app. Each event also appears on the lock screen with its name and time.
An Alternative to Mail and Calendar
Not too long ago, we noted in another article that the best alternative to the Mail and Calendar apps is to continue using the tools that you know and love. For us, the best choice is to use a Google account as a comprehensive mail and calendar client. From one Google screen you can switch from mail to the calendar quickly and see a comprehensive view of all your calendars, rather than stay limited to one. Sure, keeping extra browser windows open can be a pain; but to get a smooth and complete experience, I think it's worth the effort.
