I want to customize or replace the default calendar, similar to the default widget, but with Ajax next and previous months loading.
Ideally I would like to be able to do that (red dots are dates with posts):
The left and right parts are preview of next and previous months. But that will be a bit hard to do. Just a simple WordPress calendar with Ajax next/previous and link to days containing posts will be enough.
Maybe there is a way (a trick ?) to add Ajax months loading on the default calendar widget. The default one is simple and perfect, but this feature is missing.
How could I do that?
