My Calendar doesn’t have anything that’s totally open, showing all events in any given context. That’s partially because it could cripple somebody’s server if they tried to list out 20 years of complex events all at once — so I don’t really provide that as a default option.
You can, however, use the [my_calendar_upcoming] shortcode to produce a pretty long list of events. It includes an ‘after’ parameter, which will dictate a number of events or days to display after today – if you set it with a high number, you’ll see a lot of events. No way for me to guarantee it would be all of them, of course.
