Click on a workspace name from the dropdown list in the top left. Click on the Calendar icon at the top. The calendar opens to the monthly view for the current month by default.
To see the daily, weekly, or list view (or switch back to monthly), click on the day, week, month, or list buttons in the upper left corner.
To scan to a different day, week or month time slot, use the left or right arrow on either side of the today button at the top. Use that same today button to jump the calendar view to showing the current date.
To view the calendar for a specific date, week or month use the small month display in the top left, clicking on the date to display. You can click on the small arrows to the left and right of the month name to jump from one month to the next.
