Add a feature that allows calendar events to be removed after they have been added

[BarrelDevelopment]

Is your feature request related to a problem? Please describe.
If you add a calendar event and make a mistake (e.g. if the end user creates it for the wrong day of the month), you won't be able to remove this entry. The only option is to try to find the event in the CalendarEvents property and delete it.

Describe the solution you'd like
Provide a method to remove an existing calendar event.

Describe alternatives you've considered
Perhaps it would be possible to allow the programmer to adjust the CalendarEvents property more effectively.

@patriksvensson I implemented this feature in a fork, tested it, and it worked. Can I be assigned to this issue and open a pull request?

You don't need to be assigned. Just send a PR and someone will take a look when they have time 🙂
