Delete a bunch of events at once

We have a user with a dozens of copies of an appointment in his calender. It would be nice to be able to delete all these events at once. Deleting it one by one would take him hours. Is it possible to delete a bunch of events at once, either via the browser or even with a script or via the database?

Unfortunately, I’m not aware about such a function. It might be possible that things will change with the publishing of the Calendar app v2.0 but that hasn’t confirmed yet. In the meantime I would recommend to use Thunderbird/Lightning to subscribe to that calendar and delete the events there.

Thank you for the feedback. TB/Lightning is already the way we go.
