There are many modules/components in the extensions directory that do already this...

Thank you for your reply. But I find the components very complete, but not a simple module which recovers the native fields of Joomla.

If the module that you want doesn't exist why don't you publish it in the extension directory? I mean my point is why this needs to be in the core? If the project follows this paradigm then it should have modules for almost every possible use case which by definition it's not maintainable...

Sorry to bother you, but it seems to me that it can move the Joomla project forward and above all there are all the elements already in the heart of Joomla. I am not a developer, but it may be possible to link Joomla "date" information, like Joomla "date" fields to the Joomla mini calendar that I put in the image.
The objective is to link Joomla and its fields to a simple frontend calendar.

There are already several extensions that are available that do this.

@brianteeman complete extensions, which take us out of the heart of Joomla yes (Jevents, DjEvents). But which use the fields that can be created for an article category. I did not find any.
My idea is to use the native Joomla fields. It's not good ?

Hint: You just got a business idea ?

My request is fair for all Joomla users and that we can further exploit the Joomla fields to a calendar. I think that many of us use "dates" and it is also a module that could make a difference with Wordpress.

Modules like this already exist

then sorry to have disturbed you on 12/25. I keep looking on https://extensions.joomla.org/ but I can't find the simple solution that uses the native fields of Joomla articles.

Maybe no free such extension, but paid exist. (Search "Article calendar")
But if you want to manage events and sell tickets (regarding your screenshot with frontend menu links), it would be easier to use a dedicated extension for that task. ;-)

Hello, I don't need to sell tickets. What bothers me is that we have all the items natively in Joomla (calendar, categories, posts, fields) but nothing to tie it all together. And yet that seems logical to me. I don't have the skills and it makes me sad. This is why I am making this mini calendar request in a module.

I'm closing this issue for now. Depends on what you want to show in mini-calendar, as others pointed out in this thread, there could be third party extensions handle it already. If you want to have it for every content types: categories, articles, fields..., I'm afraid of it is complicated and something which we will never have in Joomla core.
