  • Analyze the recurring events engine to identify where rules are interpreted, occurrences are expanded, and date comparisons are made.
  • Define and implement a clear rule: interpret the recurrence rule and generate occurrences in the event’s original timezone, then convert each occurrence’s start/end to the render timezone for UI.
  • Ensure all recurrence-related comparisons (by day/range) are performed consistently with this rule.
  • Reuse the same “convert back to original timezone” logic when updating single occurrences via drag & drop or popover.
  • Add tests for recurring events crossing DST, with different original vs render timezones, and for updating individual occurrences.
