I know that there is a calendar in Emacs and I want to use it. After a lot of Google searches, and also after reading Emacs' manual, I still have no idea how to use it. The only thing I have succeeded is to view a buffer with 3 months.
What I want to do is use it like the Google Calendar so to be able to write entries in the days I want and some notes.
I have seen that there are also some other options available like the diary but the only thing I have find for it is a description so I don't actually know what it is! How can someone use Emacs as a Calendar and what are the options to do so (Calendar, Diary etc)?
elisp
/ customizing Emacs, then little by little you can have a fully functional calendar that will display birthdays, holidays, meetings, etc. in the form of multicolored entries on the calendar and a corresponding org-agenda buffer with details in the other window. I use both a 12-month (large screen) and a 3-month calendar (small screen) to display my entries.
