Day numbers and events of last day[s] of previous and first day[s] of next month

Hello this is only available in our FullCalendar Add-on https://demo.simplecalendar.io/fullcalendar/grid-view/

It does not work in the base Simple Calendar or Google Calendar Pro like that.

Any chance to achieve this with Simple Calendar or Google Calendar Pro?

I doubt it, that’s why we built the FullCalendar add-on.

What a pity!

You could always write your own customization for it, but yeah we will likely not be adding that into the base plugin anytime soon if at all.
