How it works.

  1. 01Open the calendar and inspect duplicate groups.
  2. 02Choose exact/revision removals explicitly; review potential fuzzy matches.
  3. 03Preview the remaining calendar and export.

The important details.

RECURRENCE-ID is part of identity. Fuzzy matches are never automatically deleted.

A good question.

Can two events with the same title be different?

Yes. Titles alone are not identity. Dates, UIDs, recurrence and revisions matter.

Keep going.
