According to the description,

...tasks of the type Daily can be daily, weekly, monthly, or yearly. They have special requirements: ...

a Daily could repeat "yearly". Plus, you can choose to set a Daily that repeats "yearly" in Habitica, and the parameters are basically the same as setting it "daily".

Yet when you try to use "yearly" instead of "daily", error messages appear like this:

Error:Unknown frequency type (task type daily) "yearly"

Valid frequency types: "daily", "weekly", "monthly"

I have not been able to get the daily option to function successfully. I can create Habits and To-Dos without trouble, but as soon as I add a daily, it fails. It's possible my input data is wrong, but I've followed the formula exactly.

Here is a copy of a file I am using to test.

52 Weeks of Eating Healthy, Week 52 (Dec 26 - Jan 1)
🍱Week 52
This challenge is to test dailies and habits - I need to get the daily thing working okay.

As soon as I remove the daily line, it works fine. I have also tried replacing Weekly with Daily on the line, removing the end of the line completely. I am not certain if I have an error in the formatting. I don't have an example copy to use for comparison - if I did, I might be able to correct my file.
