@@ -72,11 +72,12 @@ For each note of the calendar, the following attributes can be used:
| `#endDate` | Similar to `startDate`, mentions the end date if the event spans across multiple days. The date is inclusive, so the end day is also considered. The attribute can be missing for single-day events. |
| `#startTime` | The time the event starts at. If this value is missing, then the event is considered a full-day event. The format is `HH:MM` (hours in 24-hour format and minutes). |
| `#endTime` | Similar to `startTime`, it mentions the time at which the event ends (in relation with `endDate` if present, or `startDate`). |

| `#color` | Displays the event with a specified color (named such as `red`, `gray` or hex such as `#FF0000`). This will also change the color of the note in other places such as the note tree. |
-| `#calendar:color` | **❌️ Removed since v0.100.0. Use** `**#color**` **instead.**
Similar to `#color`, but applies the color only for the event in the calendar and not for other places such as the note tree. |

-| `#calendar:displayedAttributes` | Allows displaying the value of one or more attributes in the calendar like this:

`#weight="70" #Mood="Good" #calendar:displayedAttributes="weight,Mood"`
It can also be used with relations, case in which it will display the title of the target note:
`~assignee=@My assignee #calendar:displayedAttributes="assignee"` |
