Where to get "Obsidian codes" to work with templates?


I would be very grateful if someone could help me here.

I’m very new to Obsidian, and would like to start working with some templates.

But, I would love to use that “codes” (I really don’t know what is that - sorry for this question). As, for example, the one below:

  • {{date:DD-MM-YYYY}}

What’s it, please? And, is it possible to access some website or repository with examples of usage of these “codes”?

Thanks in advance for any help.




Thank you very much!
