+1 for itsycal.

- solid integration with macOS Calendar app (shows all your events and has a "+" option to create new ones)

- can also display a time clock along with the date and also has fully customizable datetime patterns meaning you fully replace the system date/time. I especially love doing this and now being able to just click on the date time in the menubar and see a calendar popup (instead of datetime settings which I never need quick access to) similar to the Windows clock

Yeah, itsycal has been around a while and is fantastic.
