How it works.

  1. 01Choose at least two ICS files.
  2. 02Review timezone conflicts and same-identity revision choices.
  3. 03Preview the merge and download a new combined file.

The important details.

Whole components are copied. Conflicting definitions for the same TZID block silent merging.

A good question.

Does merging remove duplicates?

Not automatically. Use Smart Merge to preview exact duplicates and revision choices.

Keep going.
