Manage your Calendar
The Calendar app lets you view and edit your schedule.
When you first set up your phone, you configured it to use an existing Google Account (such as Gmail), or you created a new one. The first time you open the Calendar application on your phone, it displays any existing calendar events from that Google Account on the web. As you edit events from any mobile device or web browser, they are synced automatically across all the places you need them.
To view your Calendar, touch 
on a Home or App screen.
To change the Calendar view, touch the date at the top and choose Day, Week, Month, or Agenda. Swipe to scroll vertically or horizontally. In the Day or Week views, spread your fingers apart or pinch them together to zoom in or out.
From any of these views, you can
SRead or edit event details. Touch an event to view its details.
SManage events and calendars. Touch icons across the top or Menu 
to search or create events, return to today, or adjust settings.
