2. either copy the date by hand (with `-` between 2-digit numbers) or click anything on the related date box on the calendar webpage (it will automatically copy the data)
3. add a new entry in the `yaml` file by pasting the date (at one more indentation level than the `calendar:` key)
Everytime the webpage load it will first get the New/Full moon dates from the API, then see if any entries in the calendar matches one of those date and if it does, add the corresponding informations to it.
