Calender view with more than one month?

Is this the calendar shortcode? You can have multiple calendars on a single page, but they will operate independently.

For the second calendar you can set a calendar to a particular date (e.g [eo_fullcalendar defaultdate="2017-08-01"] will display August in month view), but this is a static value. Rather than updating it each month you could create your own shortcode which invokes the fullcalendar shortocode but calculates the appropriate date (i.e. the 1st of next month).
